I am definitely going to get mine done. You just have to make sure they put the proper stuff in and they dont get mixed up with semi synthetic.My friend actually went up to the guy who was doing the job and reminded him of what oil he should be putting in, and said to him "it will say fully synthetic on the bill of sale wont it "
I think the trick is as someone said...watch them from the viewing area... at least you can make sure all the old oil is drained out
! If you leave it at a garage, (even mercedes ) you dont know whether they have let all the old oil drained out, especially if they are in a rush...and worse case, they could actually forget to do the oil !! ..it happens.......!
Happy New Year
