Do what you want, Mike, but I'm using Shell Rotella T Synthetic 5w40. About $14 now at Walmart for a 4L jug.
Get a good oil filter (do a search here for that - there are several good choices and other members here have already done the research), and get some extra crush washers for your drain plug from your dealer so you can change that each time, too. (They are cheap, so get several and you'll have one for next time.)
I put the Shell Rotella in at my 500 mile service which I did myself, and changed it again at 4k, 8k, and then 12k miles. Sent off a sample to
BLACKSTONE LABS at the 12k service, and it came back good. I may not do that every oil change (it's $20 for the analysis), but figured I might do it again at 20k for a reference. My owner's manual says 10w40 or 15w50 - semi-synthetic or synthetic. It meets all the specs except JASO MA (look them up in a google search).
I'm plenty satisfied, and although this is excellent diesel oil, it has none of the slippery additives that a lot of car engine oils do that increase fuel economy but would also damage our wet clutches. It works, and it's practical. Save your money for chrome, clothes, tires, or whatever else floats your boat.
