I have a 1996 Ford Explorer V8 5.0L AWD and it seems to have a slight leak around the rear of the oil pan and around the rear main location. I used Auto-Rx about a year and a half ago and since then have used a HM 5w30 and LC. I might actually try a 10w30 in the summer it there are no quality Stop Leakproducts to try. The leak doesn't leak onto the ground or anything, but you can definitly see it when you climb under the truck. Are there and good stop leak products on the market that you would use on your own vehicle? Before LC I didn't use any additives, so I don't want some snake oil additive that will either do nothing or cause problems like clogged passage ways etc.. So has anyone use a Stop Leak product on their own car that actually worked. Thanks for the help.
