Hey, all. About 6 months ago, I bought an 09 Pontiac G6 V6 3.5 base sedan w/ about 139k on it. Not a drop of fluid leaking, garage-kept, one owner yada yada - clean as hell and in excellent condition. I changed the oil about 3 months ago (Supertech synthetic 5W30, Fram filter), no sweat, no issues. Well, I decided it was due again now that it has 145k+ on it. I heard about Marvel Mystery oil, and decided to check it out. Since I was/am going to change the oil in about 500 miles, I figured I'd throw some in the oil, and burn off any crud before my next oil change. I put about 12 ounces in the crankcase. Well... since then, I have developed an oil leak from what I believe is the front crankshaft seal (I assume this because there is wetness on the passenger side frame rail right below the front crankshaft area both directly underneath the belts/crankshaft and accumulating on the frame rail underneath the same area). There is maybe 2 to 5 drops of oil after every other time I drive (I drive for about 45 min at a tie), and never when sitting overnight. I know it is anecdotal, but... did the MMO clean the crud from around the seal, thus exposing the leak, and/or did the oil thin sufficiently to seep out of this exposed leak?
Also... I bought Valvoline HM synthetic blend Maxlife for the impending oil change -it has seal revitalizer, I guess... should that suffice as a band-aid or should I add a bottle of the Blue Devil Stop Leak as well?
I know the seal replacement is cheap and doable, but I don't have time for it atm.
