My only comparison is with SS Amsoil... signature series that is. Its an acutal REAL fully synthetic... not one that is just labeled "full synthetic" which started as mineral crude oil and refined so much that it became synthetic.

Pennzoil is awesome oil, I agree. But it doesnt beat the SS line on UOA's.


Also... I did notice how the subject on the oil suddenly changed to pricing.

I cant justify paying 10-15$ a quart for minor track days. For 99% of people a good 5w-20 is fine.

Ive owned a many RX7 and there is no engine harder on oil then a rotary. Thats where I learned all of oil knowledge.

Amsoil isn't priced that bad, I can get it for well under $10 a quart. I ran 10w30 SS on my first procharged coyote which seen 200mph, the autobahn, the ring. I used it on my ZO6 also and will be using it on my 14 GT procharged.

I am getting my oil for 9 bucks or so a quart through a generous friend. :driver:

15 bucks a quart? Are you looking at refined liquid gold to lubricate your engine?

Ive some oils reach 15$. Amsoil included. I will stick with my Penn Ultra and Wix.

I just looked it up I can get the 10w30 SS well under that:driver:

That's craziness for oil prices, the most I see in my catalog is for 10.42.

Get mine at $6.00 a quart.

Damn must be a Dallas thing. I still prefer the Ultra though. The availabilty makes the choice.

Can't knock convenience.
