Amsoil Intervals?

Amsoil Fluids, Filters, and Intervals?

I am considering using Amsoil products for all of the fluids and filters in my 3rd gen 4Runner.

Anybody doing this? What particular fluids and filter do you use? What did you have to do to transition to them? What are your changeout intervals? Etc.? Does a thread already exist for this?

I would like to hear from Amsoil users only. There are plenty of threads with multiple posts that say Redline is best, Royal Purple is best, Mobile 1 is best, etc. Please don't make this thread like those threads.

I use Amsoil products on all of our vehicles, they make amazing fluids. Just follow the directions for change intervals ect. The website will tell you what fluids to use based on your vehicle. You do not need to do anything to transition to their products. The only thing you may want to avoid is running a pure synthetic engine oil if you have really high miles or a lot of sludge in the engine.
 
Their are 3 types of oils listed on their website for my vehicle, Signature Series, XL, and OE. There is a bombardment of information in the descriptions of these oils, so I am having a hard time comparing them to each other. I really don't know which one to choose or what oil-change interval to use for them.

Similar issue for automatic transmission fluid and rear differential oil. What about power steering fluid? Seems their recommending ATF for that.

Unless we have a lubrication engineer lurking here on the forums that I'm not aware of, there isn't anyone here with enough data to answer these questions.

The reality is it just doesn't matter. The difference in results between any of the quality synthetics that meet the SAE requirements for our trucks are going to be so minuscule that you won't be able to tell the difference, even after hundreds of thousands of miles.

When someone on a forum tells you that this oil or that oil is better, they're basing it on absolutely no data whatsoever. Amsoil is a fine product, but when you're dealing with vehicles like ours, that will go 400k miles on dino oil, there's no control group to tell you if it's working any better than anything else.

Amsoil is definitely no magic fluid that makes your vehicle superior. With that being said, Amsoil does extensive testing of their products and proves how their fluids are superior in several regards. Read the study they performed on the taxi cabs in Las Vegas.

As far as engine oil, the signature series is the true 100% synthetic oil and is rated for 25k miles or 1 year. Honestly, it is probably over kill for our 3G's. If I had a ZR1 I'd be running that oil. You can still use their OE or XL line of engine oils.

Amsoil does list the interval for each of the oils you listed under product highlights.

Honestly, I love Amsoil but I still run Mobile 1 Extended life in my 2011 Camry and Highlander because it is great oil and cheap at Walmart. My 4runner gets whatever cheap synthetic blend that is on sale (for the reason Jeremy listed).

Amsoil is great but so is Redline, Royal Purple, Mobile one ect. I just prefer Amsoil because it is better :party:

That "study" is just a marketing though. They're not comparing the results to any other oils!

They proved their oil works, but they didn't prove that it's any better than any other synthetic on the market.

Consumer Reports did a massive study on 20 oils using taxis back in the '90s, and here's what they found:

None of the tested oils proved better than the others in our tests. There may be small differences that our tests didn't reveal, but unless you typically drive under more severe conditions than a New York cab does, you won't go wrong if you shop strictly by price or availability. Buy the viscosity grade recommended in your owner's manual, and look for the starburst emblem. Even the expensive synthetics (typically, $3 or $4 a quart) worked no better than conventional motor oils in our taxi tests, but they're worth considering for extreme driving conditions high ambient temperatures and high engine load or very cold temperatures.

On the basis of our test results, we think that the commonly recommended 3,000-mile oil-change interval is conservative. For "normal" service, 7,500-mile intervals (or the recommendation in your owner's manual) should be fine. Change the oil at least that often to protect your engine and maintain your warranty. Even for the severe service experienced by the taxis in our tests a 6,000- mile interval was adequate. But some severe service - frequent cold starts and short trips, dusty conditions, trailer towing - may require a shorter interval. Note, too, that special engines such as diesels and turbos, which we didn't test, may need more frequent oil changes.

We don't recommend stretching the change interval beyond the automaker's recommendations, no matter what oil you use. Engine combustion contaminants could eventually build up and harm engine parts.

As for STP Oil Treatment, STP Engine Treatment, and Slick 50 Engine Treatment, our advice is simple: If you use an oil with the starburst symbol, you don't need them.

That info is a little dated, but it still speaks to the fact that there's just not much difference between one quality oil and the next.

Here's the whole thing:

I don't want to turn this into a debate on which is better (because most high quality oils are nearly equal) but Amsoil does do testing against other oils.

The taxi cab study was to just prove how well their fluids hold up under extreme conditions.

Here is the study they performed comparing other high quality oils.

In the end, all of the major high end brands make great products, no doubt.
 
If conducting scientific studies using 5 different ASTM test standards is just advertising, cool...
