Synthetic bases are better. If you want proof, then take a look at PQIA website and compare the cold flow measurements. Or, if you want a more overall impression, look at the ACEA approvals for a conventional oil compared to a synthetic oil.

I think the previous poster meant real world differences between group IV/V vs. group III/III+. Considering that group III/III+ oils can be formulated to meet some of the most stringent specs such as ACEA, VW, MB, BMW, I would say the exercise of trying to come up with a list of group IV oils is mainly academic.

Obviously, the overall performance of the oil is more important than the individual ingredients.



For sure Gabe.

David1; I know some synthetic oils are less or more then others as some have Group III and some have Group IV, Is there any out there with Group V ???

Anways a list would be nice


My question is, why?

Questions like this seem to indicate a lack of understanding about how oils are made, in spite of all the technical articles on BITOG.

ExxonMobil has made it pretty clear that they believe their Visom product when blended with PAO is equivalent to the older formulations. It's about performance, not composition adhering to prior practices.

Lol, some people are gonna be like was it supposed to be a picture that didn't show up?!!?

But this is the true list.. There isn't any pure 100% GIV base


+1. Wish the silly wife's tale about needing some high grp vi content would just go away.

Why a mix of G-IV/V is a better base to build with.. Which is what Amsoil signature series is. It's a group 4 and 5 mix.

Will they actually follow that, though?

Good Question

Im told the Mobile 1 EP is not Group IV



If anything the EP would include more pao than the regular line has to help the interval extension.

I know we have a 0w-40 distributed by co-op that says PAO in the top corner. What percentage isn't stated however a pure pao formulation has some inherent shortcomings with additive solubility being a major one.
David. The truth is whether an oil is more pao or less or all is truly irrelevant. What is relevant is the specs it meets or exceeds and how does it perform under the conditions it's placed in.
A pure pao oil isn't desirable. It's not polar and additives won't dissolve properly which means its not going to protect the engine as it should.
Oils today are a mix of most of the basestock groups. That way the finished product has the desired performance characteristics and perform as required as per the specification it meets.
A finished oil today is using a percentage or mix of multiple basestocks and focusing on just the oils basestock is a fools errand. Look at the specs the product meets.
Simple
 
I doubt that would be the best grade for your Honda.

Where did you see this? I'm interested because I used to write MSDS for a large corporation. If anything we were deliberately vague so we didn't divulge trade secrets or compromise patents.

been lookin at the MSDS info on the amsoil site, even the signature series info DOES NOT look like all group IV + or V oils! can anyone clarify?? they are using the "propriety" word like others hiding their ingredients!!!!
 
I corrected that for you.
