You sure do tend to over think alot of this stuff.
Oil is oil. You're just paying for the name on the bottle. Run mobil 1 or castrol, it truely doesnt matter which one you pick. Mobil 1 just say that the extended life oil COULD run up to 15,000 miles WITH atleast a filter change somewhere in there. I wouldnt ever trust it that long.
Just buy one of those full syn oils and a filter and run it 5,000 miles and change it, simple as that.
Or just buy regular oil because its cheaper and does the same exact thing as a synthetic oil.
