Is it a really bad thing that i haven't changed my oil in such a long time? It is a modified Trans Am, and i only drive it on occasion, so it may only have about 1500 miles since the last time i changed the oil (which was first time changing it after having engine built, fyi). Any help on this subject would be great, i haven't scoured on here too much, but it's hard to find a place that has info on this believe it or not. Thanks all!
