I've been doing ALOT of research on this topic and it's almost like a loophole .. but on to the question , I just want to get a fully 100% synthetic preferably 5w30 , I did some research into Amsoil that is what I want to go with but some places are saying its not real synthetic lol so I need some honest opinions not from ppl trying to make money.I am trying to build a consistent and reliable daily driver/track car.

 

Was also considering using their new EA air filters also .. they claim to keep more dirt and flow more than a K&N .. soo I might try it out to see whats up.Anyone try their products and have any opinions? I was looking at their oil filter as well.

 

Op, you're asking for "opinions", I don't have any on Amsoil, but I got this info from this website.


"AMSOIL synthetic motor oil is a pure synthetic motor oil that falls into the Group IV classification. AMSOIL synthetic motor oil uses a polyalphaolefins base stock. Group IV base stocks are much purer that the other groups giving it superior mechanical properties over a very wide temperature range. Group IV synthetic motor oils have a much improved viscosity index and require little to no viscosity improvers which are the most vulnerable to thermal and mechanical degradation over the life of the oil."

Thanks man I appreciate the link thats what I'm talking about

 

what is the definition of "synthetic" in regards to synthetic oil you think is correct? and compare that to the definition oil companies/marketers are using to sell the oil.

whatever the definition of synthetic, what are the benefits of that type of oil over other available oils? isn't that really why you want a "synthetic" oil? Do those benefits apply to you, such as cold flow improvement of synthetic- do you start your car in -20F weather? Do you run hotter oil temps? Do you know what your oil temperatures are?
Do you believe a synthetic oil will give you more power, or more fuel economy?
if it does, how does it do that? Are there conclusive tests showing an apples to apples comparison of that? And I don't mean tv commercials where the announcer says, "tests show...".

and there are certain conditions where conventional petroleum based oils are better than "synthetics" or PAO's.

Some may have noticed that ALL major oil brands have changed the formulation for auto oil, synthetic and non-syn alike. In the past they used things like lead, mercury and some other metals (yes, metal) in the blend, but these deposit themselves on the mesh in the convertor and ruin it in less than 100k mi. The feds say automakers have to warranty these things past 100k miles so the automakers have the oils re-formulated minus the heavy metals. The result? Emissions systems last 120+k miles, but the engines leak-down is twice as high at any given mileage. I would use the synthetic blend oil for deisel engines, such as the shell rotella, as that formula is un-changed. I don't even run cats.....................

 

I use 0w30 sso amsoil it's 100% syn it's a group 5 at least the sso 0w30. Like mobil 1 is a group 3 and a hydro process and is really not 100% syn. The amsoil sso use a amazing additive package.

 

OP, have you looked on BITOG (Bob is the oil guy) website? BITOG is an excellent source for oil information including used oil analysis (UOA) results posted by members. You will likely find what you're looking for there.

 

figure out how it works yet?

Why is this BS oil post in this forum......it sure does not belong here.
