What is the best oil for the beast.

[carter200]

Bob,
I was not trying to be rude. I do not play that game. I was just stating a factor as to why a person would "push" Amsoil. I think Amsoil is a good oil but I, too, am on the fence as to the "best" oil. I run Redline, personally with NO problems and have for 8 years.

I don't know if the good characteristics Molybdenum does what it is suppose to, or maybe too much gets wasted,but if it does Redline has high levels of it. Oil reports show levels of 300 to 600 when looking at 10w/30 and 10w/40. I haven't been able to find Moly in other oils, haven't looked at Klotz though. http://www.bobistheoilguy.com/index....d=54&Itemid=62

Mines staying together so far running Redline, with 2500 track miles at 230-250 oil temps, staying between 4000 and 6500 rpm. It's had Redline for 10000 miles since engine teardown. Hopefully it will not need to come apart again for a long time, except for upgrades, but if it does I'll report back on engine wear.

It seems Molybdenum is an anti-wear additive. Mobil 1, 5W30 seems to have about 80 ppm.

That's the first I've seen Mobil adding Moly, I wonder if they put it in their other oils besides the super-syn. Maybe the moly helps with their lowered levels of phospherous and zinc.

That's my guess.

I recently switched my 92' Z to Mobil 1 high mileage formula, not because of high mileage (it has 41,000 miles) but I've always used M1 10w30 since new, M1 HM has plenty of zinc and also seal conditioners which I feel is important to our aging engines. I also used the Bosch oil filter. I get my M1 at Wally world so for a complete change oil is less than $50.00

It definitely read that way to me, especially with the sarcastic eye-rolling smilie. But thanks for clarifying your intent.
