They say it's for lubricating internal parts of an engine, but look what oil did to this engine... I don't want that happening to mine, so I removed all of it.
It was valid question. Guy just bought car and is craving info to keep it alive. Not everyone knows how to keep and maintain these rides as good as some members on here. We don't want to scare all the new members away .lol. Or we could "yellow Bullet" him tell him to hit the newbie tread and stuff a cactus up his ass
When I go to the track I use 5 quarts of water and 1 quart of Dawn dish soap, and nothing but a quality Fram filter. (And make sure you prime the filter with sand before you put it on, the grit really helps remove sludge under harsh track conditions.)
