After reading about the "complete" oil change on this site, I changed my oil today using this method. Everything went fine, but I had a hard time getting the return line off and on... the fittings wern't the problem, it was manuvering the line itself. There is only about an inch & a half of flexible braid line in the middle of the line and that didn't help much... it would be a lot easier if more braided line were in place. I thought about adding more to it, but upon closer examination I noticed the line changes size also. It's 1/2" coming from the engine to the braid, then on the other side it reduced to 3/8" to the oil tank. Other than part about sweating like a pig messing with the line, I'm very happy with the over all results...Completely clean oil.
