Valvoline MaxLife Full Synthetic 10W-30
I use Valvoline VV180 MaxLife Synthetic SAE 10W-30 and a K&N HP-2004 filter and change every 3000 miles.
I get both the oil and filter off Amazon with free 2-day prime shipping.
I switched to this oil at 88,000 miles, I had the dealership do my 90,000 mile service then and since then I've been doing all the maintenance myself to save money.
I haven't noticed any performance gains, which you should not expect from oil anyway, but I am confident that my engine is being protected better and also cleaned better because Valvoline synthetics use good detergents.
The K&N filter is extra strong and used in race vehicles, my favorite part is the 1 inch bolt on the bottom because getting a filter wrench around the filter in my 2004 Overland is a real pain.
Always hand-tighten your filter, never use a wrench to put it back on. Just wipe the oil off and put some muscle into it and it will be fine, and a lot easier to get off at the next change.
