Amsoil vs. Mobil1

ckgdrums · Jul 22, 2005

I've been reading the threads concerning oil, as many as I can find anyway, and I was interested in what you all think is a better synthetic oil for the Titan engine, Amsoil or Mobil1? Oh, and why?

My KC XE has about 710 miles on it and I'm wanting to get info before it's time for it's 1st oil change.

Thanks in advance,

I've always been a Mobil 1 fan just because of availability and price. However, I've been swaying...

I can't find the info... but I don't think Mobil 1 is a PAO based synthetic. It's still not "COMPLETELY" synthetic.

However, GERMAN made (the famed "Green stuff") castrol syntec 0w30 and all of Amsoil 2000 oils are PAO based.

SO... what's this mean? Mobil 1 is going to work better than any conventional oil. The German Syntec and Amsoil are going to work better than the Mobil 1. Justify the price difference and see if it's worth it TO YOU.

You can't really go wrong with any of the good oils out there, but you can go BETTER.

I do like the availability of Mobil1, but there are a few Amsoil dealers here in Wichita, so that shouldn't be much of a problem either.

Anyone else have $.02?

I e-mailed that question to Mobil1 asking were if they oils Group III or fully synthetic. Mobil 1 reply was they could answer because it was proproiratery(?). So if it was fully synthetic they would have gladly answered. The Oil companies have done it to us again, we don't know what were buying. I do know Amsoil has one group III oil the XL series ( and they gladly told the trueth) about it, and all others all fully synthetic. I also knew the Mobil 1 carried Castrol to court because the were selling group III for fully synthetic and they lost . Opening the doors for oil companies to use cheaper group III basestocks and selling them to us for full synthetic prices. If your using group III you might as well use mineral based oil, it's much cheaper. All Amsoil is fully synthetic but the XL series.

Well that's good to know. I would hate to pay synthetic prices for non-synthetic oil.

I use AMSOIL on all my vehicles, it is good stuff

The new Mobil 1 SuperSyn oils are full PAO syns. Their older TriSyns are not. ckgdrums, don't buy it from your local Amsoil dealers, PM Talkinghorse here on titantalk. He sells Amsoil at dealer cost with no gimmicks. He is very well respected both here and maxima.org. Normally I get my Amsoil either the very next day or within 2 days, but normally 1 day after ordering.

Your pulling teeth asking this question. Yes Amsoil is a better oil than Mobil 1. Will you ever see the difference? Absolutely not. Either oil will keep you on the road for 100's of thousands of miles. I've been using Amsoil since 1994, using extended drain intervals the entire time with flawless results. Amsoil use to have a huge lead on the competition, but honestly, the competition has just about caught up.

ckgdrums · Jul 23, 2005

Hmmm, that's interesting. I'll get with Talkinghorse and see what he can do. Thanks for the info. Honestly, though, I suppose you're right about the difference in the 2 oils. As long as the don't break down and offer protection that's all you can ask for, right?

Mobil 1 website does claim it's PAO's and that good there not cheapening up there oils.

If you can find the German Castrol syntec 0w-30 use it and dont' look back. Why I like this oil: First its a 30wt and its ACEA A3 approved(a cert. usaully only obtained by 40wt+ oils) so you know its going to offer protection in even the most severe conditions, conditions that an ACEA A5 rated oil could possibly falter. Its a 0 winter weight, thats great for me as I live in NH and negative temps are common. You need a good oil when the truck engine is -20 deg., This oil is noticably better than any oil i've ever tried in this regard, instant non-pegged oil pressure. Many think because its a 0w-30 thats it must be a thin oil. That can't be further from the truth, most likely to be able to achieve the ACEA A3 rating GC is about as thick as a 30wt can be, where as mobil 1 5w and 10w(acea a5) oils are at the bottom of the 30wt scale, closer to a 20wt than 40. No oil seems to be able to compete with GC in UOA"s espcially when it comes to valvetrain wear. The samething that seems to be Mobil 1's weakness, that and high iron.
A 32 valve DOHC V8 requires more out of an oil than alot of other engines. A good flowing oil at any temp is essential to keep the valvetrain wear to a minimum. Also The "pent roof" cylinder head design common on Japaneese 4 valve heads conducts more heat to the engine oil/valvetrain then an OHV design would. For what its worth, most of the toyota 4 valve cyl. heads that spec. reg. fuel suffer the same problem. They cook the engine oil in the valvetrain area. Running even 89 octane drastically reduces this problem. Apparently what happens is 87 octane is to low a rating and causes severely undisirable cyl. head temps. With that in mind other than the titan and some toyota mini vans I can't think of too many 6-8cyl DOHC engines that spec 87 min. octane. Not that its a problem in the 5.6 but having an ACEA A3 rated oil in the sump means I don't have to worry about it. What you essentially get with either Gc 0w-30 or the ACEA A3 rated Mobil 1 0w-40 are two oils that allow you to have your cake and eat it too. You get the high stress protection of a 40-50wt race oil, and cold pumping ability that the thinner 5-10w synths can't match. My 2c

That's good info as well. My question is, where would a person find German Castrol 0w-30? Do you have to order it from somewhere?

Check Autozone, it's the best place to find the stuff. You'll have to make SURE you read the back of the bottle, though.

Thanks JayDee, I appreciate the help!

Both are full synthetic. Others are suspect. I don't think under a million miles you will see any difference.

How does the Amsoil Series 2000 0W30 stack up against the Castol 0W30?

Pretty much although it will not come in that packaging in the U.S. The Pkg. will look like a nomal syntec bottle. Every bottle of Castrol syntec 0w-30 i've come across has been the green necter. I believe normal crappy U.S. castrol syntec did not meet the stringent Eurpeon specs. required for some european cars such as MB, BMW, VW turbo's etc. So they imported an oversea's oil that would so they wouldn't be left out of the market. Its laughable that its priced the same as normal syntec, normal syntec is grossly overpriced, the GC syntec is grossly underpriced.

They seem to have similer certs. Although the amsoil meets MB 229.5, which GC doesn't, means the amsoil can go 30,000 Km, the GC and its MB 229.3 means its only certified up to 20,000km. The GC does meet some certs that the amsoil doesn't like bmw long life and Porsche approval, I guess you have to take it at whats its worth. Mobil 1 0w-40 is also in the mix meeting all the above mentioned certs. The GC is also starts out much thicker than the amsoil 0w-30, SAE grade visosity of 12.1@100deg. C vs. 11.2 for the amsoil. Not suprising the Mobil 1 0w-40 is the thickest at 14.2. M1 10w-30 is a watery thin 10.0 as an example.
Came across this statement sifting through the MB certs, right off the Benz site kinda of a kick in the nuts for the M1 30 weight.

some oils which are not recommended:
These 3 oils do not meet MB spec of > 3.5 cP for high temperature high shear strength.
Mobil 1 SuperSyn 0W-30 SL/SJ/CF A1/B1/A5 9.7 doesn't meet 229.1 nor ACEA A2 or A3
Mobil 1 SuperSyn 5W-30 SL/SJ/CF A1/B1/A5 9.8 doesn't meet 229.1 nor ACEA A2 or A3
Mobil 1 SuperSyn 10W-30 SL/SJ/CF A1/B1/A5 10.1 doesn't meet 229.1 nor ACEA A2 or A3

Have you guys ever heard of Schaeffer Oil? I have a friend that says it is the best oil you can get.

Check it out and let me know what you think... http://www.schaefferoil.com/

I've only heard good things about Schaeffer. But its availability makes it difficult to justify, that and I believe Schaeffer just makes dino oil and blends. Certainly a good choice if you can find it though.
