Seafoamed today!!

I respectfully disagree, and here's why.

Given that the PCV valve comes into contact with fuel and oil that is the direct result of blow-by getting past the piston rings during combustion, the composition of both products is important. There are additives present at higher concentrations in Top Tier fuel and modern day high quality oils (especially synthetic) that will help prevent deposit formation, including detergents and dispersants. If a quality oil is being used and changed at the recommended interval, in conjunction with use of a Top Tier fuel, there is no need to waste your money on aftermarket products. The composition of both fuel and oil will do their job in keeping systems and components clean.

Now for those that "chase the dime", believe that all gasoline is the same, and fill up with the cheapest product they can find, then maybe Seafoam or other "pop and pour" products found at your local auto parts store may have some effect, but still won't reverse the ramifications of using low quality gasoline. I'm sure it's a "feel good" for those that purchase low quality gasoline, but your vehicle (and millions of miles worth of data) would disagree that its an equal replacement for consistently using a Top Tier gasoline.

What is low quality gasoline? The government mandates a certain level of additive in gasoline, called LAC (lowest additive concentration). Refiners or gasoline terminals add the specified amount based on their own retail brand requirements, or their customer's requirements if its another retail marketer. The amount can vary from LAC to Top Tier, or something in between, depending on the marketer's claim sets or desired gasoline performance. LAC fuel will dirty up your engine. Plain and simple.

Ask yourself this question: Why would OEM's like Toyota, BMW, Honda, MB, VW, and GM spend time and money supporting Top Tier gasoline if there wasn't something to it? Correct, they wouldn't. They don't care about fuel, but do care about warranty claims, complaints about driveability issues, and customer satisfaction.

Now, onto the oil...The use of a low quality oil or running even a high quality oil for multiples of the recommended interval can also result deposit formation. Low quality engine oil contains very little additive of any kind. Detergents, dispersants, etc. contained in a high quality oil will keep various deposit-prone engine parts (including the PCV) as clean as possible.

Here are a few links on the subject in support my statements above, including the ASTM tests for PCV on page 49-50 (#7-9) There wouldn't be ASTM fuel tests for PCV's if fuel had no impact on it's cleanliness. Yes, these are dated, but they are still applicable today. We just have better performing additives now.

https://books.google.com/books?id=h...q=gasoline detergent affect pcv valve&f=false

Pages 14-16 speak to fuel additives, and their role in PCV valve cleanliness, as well as other parts of the engine, fuel, and emission systems.

Bottom line...use a Top Tier gasoline combined with a high quality synthetic oil and you won't need to worry about which aftermarket product to use, or how to use it. You can then spend more money on upgrades, beer, or women instead! :cheers:

Please explain how the fuel has anything to do with the PCV valve. Also please explain how fuel has anything to do with the intake runners (before the injectors).

Also explain, how detergents eliminate detonation when the fuel/air mixture is contaminated with oil.

I really don't want to start a war... and I'm not saying that cleaning the intake with sea-foam is a required process. It just makes the motor run better. That is all. If you don't want to do it (or something similar) carry on and ignore everything I said. I also recommend running an air/oil separator, but you can ignore that also. Clearly not required since Toyota did not include one from the factory.

Who are you attacking, WFO?

Nobody in particular, I just think the attitude "in general" of this forum SUCKS. So many people have recognized it and left, but it continues. No big deal, it is the internet after all. Sure would be nice if this place was more about being "open minded" and helpful vs close minded smart asses.
 
I have 107000 miles on my 2011 I feel that after the sea foam the engine has been running smoother.

I plan on getting an oil change tomorrow.would anyone recommend synthetic on my high milage truck?

Honestly with modern oils engineered as well as they are, you really aren't benefiting by running synthetic unless you want to push the limits of an oil change. Personally I would recommend running conventional oil and changing more often. Just my 2 cents, but I have used a company to analyze the oil after an oil change and even though the truck showed 0% on oil life, the results showed 22% life left. This was done with conventional oil rotella in a diesel. But the company I used says this is pretty common and they haven't seen a lot of variations from synthetic vs. conventional.

You are on your own here brother. SYN hands down over dino oil and I am pretty sure Tuskilla was joking. :-)

Let's be honest. 97% of the people on earth and 95% of the people on this forum had never heard of "Top Tier" gas before this thread. I have been driving a long time and I never heard the term nor saw it in my owners manual (did I miss it)?

The majority of people are going to buy gas based on 1-3 factors:

1) Shit. I am almost out of gas and there is a station.
AND/OR

2) That station is $ 0.08 cheaper than the one across the street.
AND/OR
3) I get $ 0.30 a gallon off at XYZ because of my grocery store loyalty points.

XYZ in my case is Loaf and Jug and they are not on the "Top Tier" list. I have been filling there for probably over 10 years and never once had an issue.

I have a buddy that is a petroleum engineer and he was once explaining how the whole process works.

First, every gas station name brand does not have a refinery. In fact, almost none do.

Lets take the city where I live. There is one refinery that serves the front range and the majority of Colorado. Suncor Energy in Commerce City. Anybody that lives here knows it because it is a huge complex (like any refinery) and when you pas it on the highway, the smell is refined (so to speak).

If you are buying gas or diesel in your refineries market you are getting gas from that refinery whether you go to Shell, Costco or Mom and Dad's Pump and Squat. Sure, the individual retailers may order slightly different blends of non-enhanced, Ethanol or MTBE (required here in the winter months) but in the end, they all have to meet the same octane testing and purity requirements.

So I will argue that the Top Tier thing - don't mean squat in the real world.

Geez, when did Colorado residents become the official representatives of the "real world"? I guess if the overly in tune, perceptive, genius, dope smokers :smokin: up there didn't become aware of Top Tier between drags on the joints or while dealin the stuff, then we need to call the consortium of OEM's and tell them that Blitzkrieg and his Colorado buddies aren't aware of it and they better scrap the whole program.

In all seriousness, I'm continually surprised to find that people join forums tied to a particular make or model of vehicle, which I would think means they care about maintaining or improving it, but then such flippant attitudes manifest when something arises that they don't know about, but actually may help them in the long run. I guess just because one person doesn't know about something, or care, it means that the rest of the world doesn't know or care either. Fascinating perspective, albeit extremely myopic.

Back to the topic at hand. I don't intend to bore the group here, but since absolutely incorrect information was thrown out here, I feel the need to address it for those that do care to know how things work with gasoline, Top Tier, and distribution. if that's no one, so be it, you can stop reading now. Please understand that I've spent the last decade working with U.S. and global refiners, fuel marketers, and fuel pipelines. I live and breathe it daily, so I'm pretty certain I have it right...

Fuel buying decisions are based on a little bit more thought than the oversimplification above. In fact, fuel quality, the potential for improved performance, and auto longevity are considerable driving factors behind the gasoline buying decision. How do I know? Reams of market research data compiled over many years regarding customer sentiment and what motivates a fuel purchase. Yes, price and grocery points definitely enter into the equation for some, but so does a concern over doing what is best for the life of their vehicle and fuel quality itself for optimum performance. Given the lack of supercharger option on the t4R, I'm all for getting 100% out of mine. Personally, I couldn't care less about grocery points getting me $0.30/gallon off of crap LAC fuel bought at the lowest possible price. If I'm spending $40K on a truck and a ton more on upgrades, I'd like to maintain it as well as possible. Apparently a large number of refiners and marketers agree with and have mined the same data we've seen in support of this mindset, given many have made a move to Top Tier over the past few years. I'm certain they wouldn't go to the expense of doing so with higher additive treat levels in gasoline if it didn't mean something to the consumer. Maybe not you or anyone you know, but consumers somewhere care about it.

Over 50% of the fuel sold in the U.S. is at Top Tier treat levels so it must resonate or it wouldn't be growing annually. Valero, the nations largest independent refiner, just went Top Tier this year. I guess we better tell them its a stupid idea too. Surely Blitzkrieg knows best what Joe Consumer wants...

How do you know if Loaf and Jug is purchasing Top Tier gasoline or not? Did you ask them where they purchase their gasoline? Just because they don't have a Top Tier campaign (most Mom and Pop's don't) doesn't mean they aren't buying Top Tier fuel for one reason or another. Or they could just be buying LAC out of ignorance or lack if interest in making more $$.

As for Suncor servicing all of Colorado, absolutely not true. Colorado's gasoline consumption is ~5.7 millon gallons per day, and Suncor produces ~2.7 million gallons of gasoline per day. I'm no math major, but no way that Suncor could keep up with the demand for the entire state, or half of it for that matter.

Below is a list of fuel terminals and pipelines that service Colorado. You are correct, not all service stations have their own refineries, but they do have the ability to pull fuel from those that operate refineries, pipelines, and fuel terminals, and can spec. the amount of additive in their fuel.

Here's how it works:

Refineries produce gasoline or diesel and move it to an on site terminal where it gets trans-loaded into trucks and then on to a retail station, or into a major pipeline such as Buckeye, Magellan, or NuStar to name a few. Pipelines move an incredible amount of fuel daily, and have different fuel terminals where fuel is taken off along the way. Seen the arguments for Keystone and the jobs/revenue it would drive? It's just like that, multiple times over. The fuel terminals across the U.S. where the gasoline goes are owned by any of a number of fuel distributors or oil companies, many you have probably heard of before. Exxon, Shell, Valero, Suncor, P66, and a hundred others. There are thousands of terminals across the U.S.

At the terminals are truck racks. A retail marketer or wholesaler sends in a truck to pick up fuel. The driver swipes a card, the computer recognizes him as XX company, and the gasoline is then dosed with the appropriate amount of additive per their contract with the terminal. Boom, they just pulled fuel from somewhere other than one refinery in that region (Colorado in your case). Gasoline is "fungible", meaning that it's traded between fuel trading entities all of the time, typically when a particular refiner doesn't have a refinery in a state or region, or their own pipeline in that area. The truck rack treats it to a specification, which becomes the differentiator at the retail level if LAC+. Many times a major fuel marketer (pick one), will have their own additive tank at a terminal or truck rack so that they can maintain the quality of their fuel using the same additive system everywhere. The fuel may not be that from a particular refiner's own refinery, but its of the required specification and contains the agreed upon additive system.

Its not about Octane or "purity". Gasoline has to meet certain ASTM specifications, including Octane so its a given. It's about additive content, Top Tier, Top Tier +, LAC, or something in between. It's about gasoline detergent, performance, and subsequent marketing claims. Have you ever heard of Shell V Power? Not just a marketing campaign. There is data backed science behind it.

Any fuel brands that go Top Tier must treat at those levels for ALL of their retail sites. Costco is Top Tier too, but then again I'm sure you weren't aware of that either since you could care less about what you put in your truck, as long as it's cheap. Guess you are only here to see how to put all of the cool accessories on your truck for the bling factor. Your prerogative to buy cheap gas and dirty up your engine, but don't say I didn't try to help keep the parts under the hood clean.

Well said.

I've always put chevron in my vehicles, but have recently gotten a bit more relaxed about it, since it seems like most big brands have caught up on the additives.

Good fuel make sense, but like I said before, I still think there is more that can be done to keep it running at its best. The PCV oil contamination issue is real. Not a "blow up your motor" type issue, but it is not ideal. so I do things to mitigate it and it works. I've pulled the intake and heads and compared (not on a 1grfe, but on two identical motors). That pretty much set my maintenance pattern going forward on motors that I care about. I don't really care about all of them that I own. The ones I care about all get a air/oil separator of some sort and annual cleaning.

Not if you have 100000 miles on it but thanks for posting in.

This forum is informative in ways, but some of the members are jerks

The FJ cruiser forum was much better.

Thanks to everyone who gave real answers and stayed on topic.

Just an FYI you can always head over to BobIsTheOilGuy. Lots of good info. Was grateful someone shared that with me I thought I would pass it along. :)
 
You have all the answers Texas dude, so I won't even counter.

P.S. - There are just as many people in Texas (or anywhere else for that matter) per capita who smoke pot as there are in Colorado.

We here just realized (go do some fact checking on intelligence and education level by state) that marijuana laws are a waste of time, money and legal resources so we legalized it.

You know what has changed since marijuana was legalized? Nothing. People who smoked pot before still smoke and people who didn't, don't. The state has made a shitload of money taxing it and has put a serious hurt on the drug dealers and cartels though.

I hear Texas has a serious drug cartel problem. Maybe one day you all will see the light too. ;-)

Edit: And P.S. - I personally do not smoke pot. Not my cup of tea, but I really don't care if somebody does. I don't think pot is anymore dangerous than alcohol, which is legal and causes all sorts of problems daily all over the world.

Wow, your post just blew my mind, I think it's because I'm high... sitting at 9800ft and oxygen deprived that is. I certainly know who to chat with when I want detailed refinery and pipeline analysis though, good post!

I think more people around here need a sense of humor, everyone takes every post so personally, maybe they should visit CO and partake.

Don't have all the answers by any stretch, but am a data driven guy, and have a passion for my job which tends to bleed over into my hobbies.

I was truly kidding and just yanking your chain about the weed stuff, which is why I put "in all seriousness" in the next paragraph. I really like Colorado and definitely realize we have our own issues down here (especially in large cities and border towns) with cartels and drug problems as do most states bordering Mexico. I don't smoke the wacky tobacco either, but have friends that do and I don't hold it against them. To each their own I say!
 
HEY! Don't leave us Washington guys out of this! It's legal here too!

In fact, I think I'm going to load up my bong with some Seafoam! :bolt:
 
Thank you [MENTION=111345]Texas777[/MENTION] for the impressive post on Top Tier gas. I have been basing my gas purchases on info like you listed, this just further backs up what I have read. I appreciate you taking the time to write all of that up. I'm also glad you mentioned Costco as Top Tier, as that is what I have been getting. My wife thinks I am crazy, but whatever. In the end, it's your car, your repair bill, and lastly your opinion of what you think you need to put in your car. It's your job as the consumer to educate yourself. Maybe Seafoam helps, maybe it doesn't. Put it in your car or don't.
 
Devils advocate here. Straight from the Seafoam website Using the vacuum line method of cleaning engines with Sea Foam Motor Treatment - Sea Foam Sales Company

" The vacuum line method should only be attempted by certified technicians having a comprehensive understanding of engine induction systems. Without professional assistance, use Sea Foam Spray Top Engine Cleaner and Lube for cleaning deposits from the air intake system, intake valves, combustion chambers and pistons."

Just busting your balls, OP!

Now, allow me to troll for a minute:
I went to the seafoam website. I saw a picture of a tractor, an illustration of a 1964 F-100, and a cartoon drawing of an ostensibly old-timey mechanic named "Jim," whom we are urged to turn to for any questions. I went all through the site and couldn't find their section on modern toyotas.....but I digress.... Maybe I'll ask Jim.

I've always been skeptical of these miracle engine treatments. Like those old stories that say a 200mpg carb has been invented, but the oil industry quashed production. If it was that great, we'd all be told to buy Dr Toyota's Old Fashioned Down Home Miracle Motor Tonic, and use it at every oil change to remove Debilitating Miasmas and put the pep back in our step. I choose not to use it. If anyone uses it and it works for you, I'll be the first guy in line to supply a high five and/or fist bump.
