'94 ThunderChicken LX V8, 70k mostly city miles. The 4.6 has seeped a little oil for many years. After I checked for burning and blow-by, a mechanic put it on a rack and confirmed it was coming from the rear-main seal (as expected).
Last summer it lost about 1 quart during a little trip of 800 hiway miles. Not enough to get all excited about, but, on the other hand, I hate to see the recurring spot on the garage floor.
Aside from fi cleaner, I'm not an additive user but ... Lucas has a good rep. Is there any reason -not- to try their Engine Oil Stop-Leak product?
Thx, P
