just wanted to say that the other day i did a motor flush, bought some GUNK MOTOR FLUSH from wally world it looked and smelled like diesel but it seemed to do some good, truck ran pretty good after that, but actually never run bad.

 

I use the same stuff. Seems pretty good.

 

i could actually tell the the difference when i was letting it idle for 5 minutes when i put it in but that may have been because it thinned the oil a little.
