hks make an oil, i think its 15w40 so that would give us an idea to what redline would be making.
changing oil is very important, we just retuned a tx3 turbo only to realise the oil was gone (only bout 3000kms) n it sounded like a tug boat. so we put it up on the hoist, changed it. sounded like gold again
moral : change ur oil all the time, its almost as important as insurance
btw stirlo i think u hit the nail on the head
0w50 is prob better than 15w50
hmmm wheres sydneykid when u need him?
