Yamalube Ring Free

I swear by this stuff for my Mercury (and know at least one person who should too!) and am curious if anyone has tried it in a car... Seems some last year said they used it in their high mileage truck but can't recall.

One of the kids put 87 octane in their Acura (which is supposed to by premium only) and now it runs rougher than a 5 cylinder OptiMax 200!

Thx,
Scott

I was talking to some boat engine mechanics and they swore by the stuff.  Mentioned that they used it in their personal vehicles also.  Both were trucks.  It's salty $$$$  but it doesn't take much to keep an engine maintained.  Only hassel I see is pouring just what you need into the tank.
