Ultra seems to be becoming tougher to find around here.

I just started using Amsoil. Always ran Mobil 1, but since camming my car I wanted a synthetic blend with a good Zinc content. A lot of oil manufacturers are reducing zinc in their oils because it supposedly clogs up the cat cans, and the government doesn't like it. Who knows what else they're skimping on.
In most street applications, I've yet to see a trend of proof that high ZDDP was actually required.
Cars with aftermarket cams have recently started seeing more failures (wiped out lobes/lifters) as the ZDDP content dropped from a lot of oils.
I've never given Quaker State Ultimate a solid look, but it does appear to be a good OTC choice doesn't it. Shocking!
Unleashed, I have been working none stop and havent had any time to myself to buy some oil.
But..... penzoil Ultra in that chart looks like did the best out of all. Do you have any data for amsoil to see if it showed even lower numbers than the penzoil ultra?
When it comes to NOACK Volatility, Ultra rivals Amsoil Signature Series. GTL base oils have the lowest NOACK Volatilty, but by a very narrow margin.
Amsoil does have a more robust additive pack, and rumors have passed around that a change to GTL may be in Amsoil's future. If it's worthy in other areas that is. There are other specs I have not been able to locate for GTL base oils, like frictional coefficient comparisons with PAO\Ester base oils. The jury is still out, but so far, Ultra is making one heck of an impact.
The only setback is price. Ultra is expensive per quart, ~$9.xx
I know you are an amsoil guy, but here it goes,
would you say in "overall" performance, penzoil ultra could be a better choice than amsoil sig series?
Unleashed, what's your thoughts on T6 5w40?

Latest sample from RP HPS is in, the results aren't "terrible", but other concerns are confirmed.

is there anything Amsoil SS 10w30 does better than PU 10w30? After seeing quite a few UOA PU seems to be beating it in every category...Do you think PU should be the new perfrormance oil?
thnx UB:rockon:
I will be honest with you folks, i put amsoil atf in and removed rp syncormax based on this thread and my tranny shifts much worse. with rp syncromax it was normal.. with amsoil atf it sometimes gets stuck. i shit you not, i have to use a bit of force to pulll it out of gear :shrug:.. this happened right after the fluid change and i drive my car like a grand pa for the most part.
i put the entire gallon in it.
I haven't seen any Ultra UOAs. Can you post some?
GT500?
