Is anyone using the new Mobil 1 Extended Performance oils? I think with the additional 50% more SuperSyn PAO, these oils are going to be great. I believe the GF-4 spec has made many synthetics a bit weaker. I'm looking forward to seeing some oil analysis reports with these new oils.

Hi I have an Amsoil Dealership and we have been selling synthetic oils since 1972 - we were the first. Check out my site www.syntheticreliability.com and click on ABOUT AMSOIL to get all the info about synthetics.

Hi, thanks for the link. I'm a member at bobistheoilguy.com. I'm quite familiar with Amsoil. At the moment, I believe Amsoil holds no advantage over Mobil 1 or Redline other then maybe marketing.

What is Supersyn?

The first?


PAO In fact, on their own they are hopeless 'boundary' lubricants, with less load carrying ability than mineral oil

M1 and Amsoil moved away from esters. Castrol are now using unique esters

Quote:

Firstly, the electrostatically-held layers at metal surfaces do not obey the laws of Newtonian flow, so the ‘macro’ viscosity of the ester does not apply. There are, for instance, some viscous low-polarity esters that are not strongly attracted to surfaces.

Secondly, my wear and friction tests show that the more ester the better the anti-wear performance; this ‘surface concentration’ may be OK under light loads, but at high loads and rubbing speeds a dynamic equilibrium is set up with the ester layers being constantly removed and replaced.

Also, we must not lose sight of the fact that the ester (and PAO) content of a lubricant has other jobs to do! (Jet engine oil is 99% ester so that it functions reliably for tens of thousands of hours from -40 to 300C; replace it with a spot of ester in mineral oil or hydrocracked mineral oil and it would soon drop out of the sky.) So there are still good reasons for using genuine full synthetics in high-performance engines…………and no excuse for cynical blend-cheapening exercises! (See Castrol RS lab. reports.) JR

The Green/Red elves may be right!

So a little ester goes a long way?

If Mola is correct 10-30% then 15% from Castrol is in the right ballpark.

20% from Silkolene

50% from Motul or Redline perhaps OTT

or a dose of Auto rx!

The natural performance oil is ester based but with the right additives?

guess I need to put a bit more Redline im my mix. Half quart is not enought at only about 5% ester total. Two quarts would be pretty nice. But I wonder about the benefits. I think there are a variety of benefits from ester and each may have different needed levels of ester to be effective. For example, we know that Auto Rx which is supposed to be all ester is added around 6% for cleaning, but at only around 1 to 1.5 % is supposed to maintain a clean engine. (Hmmmm, wonder why they say a maintenance dose of Auto Rx and in the same breath recommend full treatment every 50,000 miles? Must not actually maintain.)

Im confused "no wisecracks please" I think in french and have difficult in translation sometimes. heh heh

Joe writes: Are you saying that ARx is 100% ester? The 6% you mention is the amount of ester in your engine oil if the required amount of ARx is added?

Non confused part:
@MGBV8:What percent of ester would M1 have? I use the extended 0w-20 or 5W-20

I bought a few bottles of ARx and going to start the experiment with my daily driver this weekend.

It is my impression that AutoRx is all (100%) ester and so 2 oz per quart would be roughly 6% of your oil.

M1 is in ester denial.

UK version states 3 Synthetics
PAO - AN - what is third?

MGBV8, where does Mobil list AN as a basestock? UK site?

A Guess a 3 Synths?

Thanks for the link. I guess I meant, where does it say Mobil 1 contains AN's? I agree with you though, its probably PAO/AN and Esters.

When is an ester not an ester?

PAO's and Esters I know. What is the acronym AN for?

When it's animal fat used in automotive lubricant applications possibly ?

Womens make-up are made of esters . Do we put that in our oil ?

Alkylated Naphthalene


Better thermal and oxidated stability than mineral oil, PAO, diesters, alkyl benzene
Hydrolytically stable
Good additive solvency
Better elastomer compatibility than esters
Non-emulsive
