make sure you take the fill plug out FIRST! if you can't get the fill plug out theres no reasont to take the drain plug out. Spray the bolts with some penetrating oil multiple times a few days before you intend to change it and it will make the bolts much easier to get out. I used 80w90 even though it calls for 75w90 because I couldn't find 75w90 at the autoparts store. Mobile 1 synthetic is the best fluid IMO, i'm sure MB fluid is good too (but over priced)
