I agree! Spend thousands on an Engine and cry about $7 a quart oil!

Right. People can buy Pern Grade, Driven and the other quality oils from Summit for about 10-15 bucks a quart depending on brand. I think of motor oil like I think about motorcycle helmets. You have a 15k bike and a 100 helmet. Must have 100 dollar grey matter....
