I use Mobile 1 0w-40

The standard grades are not available over here and have to be inported. I checked with Marc first and he said it would be perfect for my engine - I guess he knows as he built it!! Its done over 12000 miles in the 1 3/4 years since he built it and its doing just fine.

I think regular oil changes are the key more than what make oil. Especially when you consider the amount of old oil that is retained in the engine at an oil/filter change.

Amsoil AMO 10w40 Zink.

M1 since 88.
My 90 BMW 735i had racked up 267,000 miles and was still running strong when I sold the car after 16 years!
All my Vettes (84 Z51 after 1988?, 91 ZR1 and 94 ZR1) and assorted cars been running on Mobil 1.

M1 in everything I own including my fugly looking S-10 beater.

That said I just CHANGED the LT5's oil yesterday ... it now has Amsoil AMO 10-40 with the zinc. My plan is to test the oil every six months to see what is happening and then schedule my oil changes accordingly.

I just made the switch to Amsoil 10-40.I did this to see if it quiets down the cam chains abit.

Thats what I am using...but I am using 5W-30

I don't mean to be a wise guy, but I just looked in my 90's owner's manual and it says to use 10w-30.

Where did you find the 5w-30 info?

I understood from reading and talking to Marc H that anything "5W-" was too light for the LT5.

I use the Mobil 1 0W 40 too, the European Formula has the extra zinc and is only $5 a quart when on sale.
