Any reason why you wouldn't use it in your car?
I love the stuff! Makes the RX run like it's on fire and I've had many friends who have solved lifter noise problems by running it in the oil. The legacy loves Techron, but that darn stuff is expensive! I've just recently used the marvel in the legacy and it seems to be running better.

I think using it as an internal engine cleaner may not be the best, as it works rather quickly and can dislodge chunks of debris, potentially causing more harm than good. It will thin the oil, possibly out of grade. Many engine cleaners that use similar ingredients advise not to drive the car with the additive in the oil.
It may be ok as a fuel additive, but I find it's use unnecessary.

I usually run with 1qt in the crank, but since the car leaks so much oil, it probably doesnt stay in for long.
If you want to use it, just add 1qt to your crank after an oil change. Then just top the oil off with regular 10/30 or 20/50, whichever you use. If you are going to use it in the gas, just add it to the tank as specified. I usually put a quart in with a 10gal fill up every other month or so.
Seafoam seems alittle more harsh on the engine than a good shot of MMO.

That's interesting - I would say exactly the opposite. My car seemed to run rough with the MMO treatment, especially when added to the crank. I add a third to half a can of SeaFoam to the crank every other, to every third oil change, 500 or so miles before I dump the oil, and have had great results. Also, sucking up a can into the throttle through one of the vacuum hoses, twice a year, really smooths out the idling.
Just to add, I have a friend who has had his single engine pilot license and has owned his own plane for many years. He was the one the recommended MMO to me, as he and his mechanic are both proponents of it, and use treatments regularily on his aircraft's engine, a Cessna 152.
I guess it's just how each of our experiences go...
