Mobil Oil

[<<<<]

There is flood of this brand in local stores. Mobil ( note: not Mobil-1 ) oil is only $1.17 here in Midwest. Is it same manufacturer as Mobil-1 or is it just name for non-syntetic stuff? I'm puzzled, Mobil stuff was most expancive around, how did they get dyno oil to sell so low? I pay $1.79 for Castrol GTX, if Mobil as good as Castrol I'll switch now, because price is right. Does anyone knows anything about Mobil (not Mobil-1) ?

Is it Mobile Drive Clean? If so then it's probably as good of an oil as Castrol GTX. If you change your oil every 3000 - 3500 miles, either oil would be OK. The best conventional oils are Chevron, Havoline and Pennzoil.

I was thinking like you last week. I noticed my Castrol GTX is $1.79 and I noticed Pennzoil at .89 at Pep Boys with rebate.

I remember reading Consumer Reports saying all oil are basically the same, just to sure to change it often.

I decided to stick with Castrol, but with prices flutuating like they are, it makes it tempting.

Mobil is with Texaco and I am sure their conventional oil is fine. Changing oil at 3,000 to 3,500 is a good idea like "iontrap" said, I would not go over 5,000. (I go 3,000 on conventional oil myself.)

I also find it interesting that I pick the more expensive Castrol GTX while "iontrap" says Pennzoil is better. Bottom line, most oils are good, changing oil is the name of the game.

Pennzoil coats your engine and gums it up, causes some serious damage. I remember opening up some different engines that used Pennzoil and it was pretty nasty. I will never use that type of oil in any car I own. Valvoline is pretty good oil, I'm going to use regular oil for the first few changes to about 10k miles then switch to Mobil-1 from there.

Now I'm confused. I bought 3 cases of Pennzoil because it was on sale and it will take few changes to use it all. I always heard that Pennzoil was pretty good... I've used it in all my cars and never had any problems. 2 of those cars had 100 000 miles and they were running good. I wonder what other people here think about Pennzoil....

Pennzoil (and Quaker State) used to advertize that they were made with "pure Pennsylvania crude oil."

Pennsylvania crude oil is high in parafin.

Parafin gums up engines.

I have no idea what the quality of these two products is today, but I gave up using them 25 years ago, and don't plan on going back anytime soon...

Quote...Pennzoil coats your engine and gums it up, causes some serious damage.

These API spec oils are pretty much the same oil. Pennzoil does not coat engines, something else was going on and the oil was just along for the ride. These oils represent a chemical soup. Base stocks come from just a few places and the additive packages come from even fewer suppliers. No one oil is really any better than any other for the same spec. It cost money to make it better and believe me no one is doing that unless they are chasing a specific spec and if they do that, they will tell you that, on the bottle.

So for a given spec, choose the price. If you want something better then you're talking differences and that's synthetic, synthetic blend or fake synthetic, that is Group III base stocks.

These more expensive oils still pick specs, usually lots of them, and for the consumer it's choices that represent some real differences. One of these oils is from big corporation, a factory fills for expensive cars and big on marketing, Mobil 1. Another is sold by preachers of the word and the word is Amsoil. Still another is Purple and it has a secret ingredient, owwww. And last in my list is an old standby, Red Line, a small company, so small you can call Roy the head chemist and talk about his oil and by his hand crafted products.

The point here is, there is not much choice, other than price for the basic API package oils. If you want something different you have to step up into the world of synthetics in all their flavors and colors.

Red Line is good stuff.

If you want to find out how well your engine "likes" the oil you're using, do a used oil analysis on it. Not all oils perform well in all engines. Before I switched to synthetic, my V6 did very well with Pennzoil. And one other factor to consider is the filter, which brings on a completely new set of opinions.

I'll keep using Castrol GTX dyno oil. One thing for sure, I'm not using Toyota brand oil. For $ 2.47 at local dealer per quart, Toyota stuff is not measuring up to $ 1.79 of Castrol. It may not seem like a lot, but consider: 68 cent difference per quart times 5.5 for V-6 = $ 3.74 per 1 change, times 4 per year = $ 14.96, times 10 years = $ 149.60. That's 150 bucks over average life of the truck. Toyota stuff is good, but not competive when it comes to price. Besides, it can't be that much more advanced than any other leading brand. O, yea, I can't stand sale slogan: "specificaly formulated for toyota vehichles"... Is Toyota getting their metalls and other chemical composits on other planet, that requires oil from that same planet? Comon Toyota Advertising, at least respect our ego, since there is no respect for our money.
