For the diesels, Rotella is my choice. I don't know if they have it State-side or not but there is a 15-40 Rotella-T that is considered a truck oil and therfore it still has a zinc additive that was banned from auto oils.

Should I make the jump to synthetic? Is full syn better than part syn? Mobil 1 vs Castrol full syn vs Castrol part syn? I'll probably be driving about 10K per year. I generally change every 4-6K, which happens to be about 2x per year.

There are many confusing lables such as Mobile Long life oil. Not the same as Mobile 1 synthetic.
If you decide to use a 10w30 mineral oil this is ok,, changing at 5 to 6000 miles. I don't like to change oil nor worry about waste disposal so synthetic cuts my work in half. When I had 4 vehicles running I was changing oil every 3 to 4 weeks. With synthetic it dropped to 1 / car every 6 months. So my work was reduced not to mention all the waste oil I had to carry to disposal. The cost of the oil for synthetic vs. mineral given extended oil changes is about a wash but my efforts are reduced. So your choice. But if it were mine I would use Mobile 1 10w30 or 10w40 in the engine and drive on.

Kevin, if i were u i would switch to royal purple. It protects the engine alot better then mobil one. Its only 50 cents more a quart and if u do it your self it is worth it. I did and it also uses less oil. I also dont do the 4 to 6k interval. I do it every 3k

I also use Mobil 1 5w20 full synthetic. My 2000 v10 manual said 5w30, but i called mobil 1 and they said 5w20. My truck has a little over 105000 mi on it and it uses a quart or a little more every oil change (7500 mi intervals)
As far as royal purple vs mobil 1, I think the difference is pretty much nil. Both are very high quality, full synthetic oils. Basically i think its kind of whichever makes you feel warm and fuzzy inside. I know guys that swear by royal purple, but I also know that porsche and a couple of major automakers recommend and come from the factory with mobil 1. I can't imagine it makes any difference in real life...

Sounds like I switch to Mobil 1 full syn - readily available at Wally World.. and change every 10K. Hmm.. but.. if I change every 5K, that includes a filter change.. so now at 10K I'm changing my filter 1/2 as often. I use the Motorcraft 820S.
Since I drive about 10K a year.. might I be better using non syn and changing 2x a year? Is time really a factor in oil? Or is usage?
What weight? Specified 5w20? or a little heavier.. 5w30.. 10w30??

Dont use 10w30. The people in the v-10 forum say that the 10 weight oil is to thick for the v-10's oil injectors. I would change it more then 2 times a year. When u get it changed at lube stop they say every 3k or 4 months. Atleast that is what it says one there stickers that they put on ur winshield. Ud be fine with 3 times or 4 at the most i think.
