I need some assistance here i'm about to go the dealer. I had my oil changed at Jiffy Lube. I think that was a huge mistake. Now the oil idiot light comes on periodically. And then goes away . Today it actually started to scream . Good thing i was 2 blocks from home i just parked it . Any thoughts ? I'm sorry if i'm asking a question that was posed b4 . I'm still kinda new hear. Got a 98 Cat with 75k on it.
