ATF doesn't hurt seals, it's oil, very light weight oil. Has additional additives and cleaners but oil none the less.

I was told: “never use one of these Ingersol Rand air impact guns without first squirting Marvel Mystery Oil in the air quick connector.” It worked “Marvelously” for that. Now that is a use I will follow. I have always used "air tool oil" for that. But when my little bottle (with drop stem) is empty, I will refill it with MMO. When I was running Alky injection, I stored the pump during winter by filling it with MMO and putting the pump in a zip lock bag. It helped keep the pump seal from shrinking (drying out).

Probably not, but I had ATF swell polyurethane badly due to the additives so am wary... Engine oil will destroy rubber motor mounts and suspension bushings as well. I would imagine it would do the same to polyurethane.

I'd like to try it on a loud lifter car at work. Do you add a quart to an engine, generally speaking? Do you add in place of one quart of oil at oil change, or change oil and refill with same amount of oil called for, plus MMO?

Just throw the quart in on top of the normal level. Done it plenty of times, nothing to get scared about Just don't leave it in there. Change the oil and filter after a bit.

I'm sure it's dirty. 5.7 with over 100,000 miles and I haven't checked idle or engine hours, but for sure very high. Not the best maintenance here. It just came out of fleet for lower rad hose and I think they did oil change while there.

Ok, I was waiting for one of these to rear its ugly head-- this will not work on an MDS engine unfortunately, 99% of the time thats just a down right failed lifter usually taking a camshaft with it. And not to start any kind of tinkle match, but I've ram trans fluid and MMO in oil for the duration of the life of said oil until its next change.

I happen to know this poor car got ran without oil for a period. Damaged oil pan, gasket blew out....long story but it got driven back to shop with oil dumping and had to be out of oil or close to it by time it got back to shop. Nuff said on that. No it was NOT me. After this is when tap tap tap started. And remember, over 100k hard miles and tons of idle and engine hours.
