These files attached are the refferals I use. The fluid evacuator is a one time purchase and a lifetime help. It made it extremely easy and fast (once I figured out operation.... Im a man, I dont like instruction manuals )................... Some say you cant pull out the full 8.5 quarts of oil with them.... I did. So just make sure when draining either way you unscrew the oil filter and release pressure for whats in it to drain. Good Luck!
