My buddy's a wrench head and was tellin me about putting a liter of ATF in the oil about a 1000k before every other oil change can really do a nice job of cleaning ur motor. An1 in here ever do this?

 

I think a quart of Marvel Mystery Oil would be better and probably safer for the engine.

 

is that a caustic oil aswell?

 

I've heard the old mechanic's tale of ATF in the oil to quieten down valvetrain clatter or free a sticking lifter, but never as a cleaning agent.

Best way to clean your engine out and keep it clean, do regular oil and filter changes, use quality materials and you will have no issues.

 

ATF does work as a cleaning agent. Most commonly you'll hear of running a bottle through with a tank of gas for cleaning injectors and the fuel system.

 

^^yup....it's a cleaning agent. Hell I use it for cleaning tools! I don't do it much on my newer cars, but I'd run a quart of ATF in the engine oil for a day or so before I change the oil. It cleans out gunk. Back on my old engine in the ranger, I'd use a solution of Lucas Oil fuel treatment and ATF in the gas tank. I saw some good results from it cleaning my gunked out injectors after I ran the truck dry.

 

I always put a quart of ATF in the day before I change the Oil.

 

Once, when I didn't have access to a lift, I tilted the transmission pan the wrong way and took an ATF shower. I don't recall feeling that clean.

 

Haha I will clean grease off your hands like a ****

 

When I fixed my tcase seal, I only needed 2 quarts to fill her back up. But...I went ahead and bought a gallon just for it's multiuseability. (is that a word!?)

 

Now before adding The ATF, do u drain some oil out first? or just top up?

 

SEAFOAM

 

not 1000 miles prior to the change though... if you use seafoam only put it in less than 100miles prior

 

an oil change cost what 15 dollars?

 

whats this have to do with anything?

seafoam is powerful **** and will wreck the oil if you leave it in too long

 

well not ****
