what kind of oil should i use?

I use Vavoline Racing Oil 20W50 .. I have had good luck with this oil and other 1G owners I know have had good luck with it also. The price per qt. not out of control either.

Redline Racing Oil has to be the best. It is a full synthetic and costs about the same as other synthetics, like $6 a quart. It says on the bottle(i don't endorse this) that the oil will last up to like 25,000 miles on one oil change and it can actually add like 5 or 6 horsepower.

Redlines not the same price as other synthetics. Its definetly more expensive. A quart of mobil or valvoline costs like 4 bucks. At my local speed shop redline is almost 8 bucks a quart.
