On Syn. I go 3000 miles. I use Mobil 1 in my truck and love it. My buddy uses Royal purple and lives by it. I am going to run royal purple in my 98'Z28. Mobil 1 filters are top of the line and are pretty resonabley priced

The slightly longer/taller Mobil 1 oil filter and 5.5 qts. of Castrol 0-30W German synthetic, proven via this website to be the absolute best choice for the LS1.
Nuff said. Good luck.

Anyone use high milage oil when the car is over 75,000 miles?

(just thought i'd ask since I didnt see the milage in the OP's sig and it was never mentioned)

I do the same thing. But that still only amouts to two oil changes a year
I do one when I get my car out of storage in march or april, then again 6 months later right before it goes back into storage. That tells you how much my car gets driven
>3k a year

Actually a filter is a filter and a filter is a filter... Have you ever cut every filter open? They are almost all the same thing. Your buying the looks and the name brand. I personally use Fram on account of the rubber on the outside its much easier to get off.
