I have a 94 Saturn SL1. I noticed, when I switched to synthetic oil, that there was a leak coming from the front right corner of the engine somewhere. The leak got faster and faster over time with the synthetic oils reaching a leak rate of almost a quart a week. I purchased STP's Stop Leak and added that to my oil. The leak has stopped completely. Any suggestions about this product or suggestions for the future to prevent the leak from reoccuring. It's been recommended to me not to use synthetic oils on an engine with as many miles as I have(160K) and that Valvoline MaxLife should maintain the engine. I'm usually not a big fan of hokey oils so is this Maxlife stuff the real deal or just a marketing ploy?
