For you guys running Amsoil, what viscosity are you running on? I'm on the 2000 series 0W-30.

 

Used to run the turbo forumlated 10w-30 but in retrospect, it's all too reminiscent of an Amway type scam

 

Amway stuff was ridiculously overpriced.

Some local places are carrying Amsoil stuff now but I just get it directly from Amsoil for the preferred pricing.

 

I was making reference to how anyone can become an Amsoil "dealer". It's really quite funny. I don't doubt that they were the "first in synthetics" and all of that, it's just their pyramid scheme like marketing plan that is a little creepy.

 

Rotella-T Synthetic 5w-40!

Because they dont make Mobil1 T&SUV 5w-40 anymore

 

10w-30 (as per manual) Amsoil (as per me and my experiences.)

5w30 mobil 1 in the daily beater...(Hey, it leaks oil and money don't grow on trees! )

 

That's what I thought too! But:
In holland there has been a major test for Subaru's regarding viscosity and guess what: 5W-50 and 10W-40 came out best, followed by 5W-40. Interesting detail: 10W-40 were mostly semi-synthetics... In 2004 this was repeated and now the results were: 5W-50, 5W-40 and 10W-40 were best. 10W-60, 0>10W-30 and 0W-40 were less good (but still above norm). Test was made in conjuction between the Subaru club and American based Kendall...

 

Could someone explain the meaning of PAO, di-ester, tri-ester?

In UK they recommend Motul 300V 5W40. I would like to know if this oil worth the extra money.

 

PAO = Poly-Alpha-Olefin, which is basically the 'synthetic' oil base itself. For chemistry:http://en.wikipedia.org/wiki/Polyolefin

"Many poly-alpha-olefins have flexible alkyl branching groups on every other carbon of their polymer backbone chain. These alkyl groups, which can shape themselves in numerous conformations, make it very difficult for the polymer molecules to line themselves up side-by-side in an orderly way. Therefore, many poly-alpha-olefins do not crystallize or solidify easily and are able to remain oily, viscous liquids even at lower temperatures. Low molecular weight poly-alpha-olefins are useful as synthetic lubricants such as synthetic motor oils for vehicles used in a wide temperature range."

 

i see that many evo owners use mobil 1 10w-30 and its ok if you are stock,but in my personal opinion if you race your car and your not stock you should get better protection i use mobil1 5w-50 its thicker and i have found that using this oil my temp oil is much cooler now!

 

I only run their Turbo Formula 10w30.

The GF's Integra gets their 5w30.

 

I use 10w30 royal purple every 3,000 miles
