If you are asking if you should switch to synthetic oil? Yes, it flows better (faster) in cold weather and has little to no break-down over time. Also tends to be cleaner, little or no sludge. As far as fuel goes, 87 octane should be fine. I run 87 all the time in my 06 no problems. Hope that helps, cause I am not too sure what you were after. lol! Btw love the yellow. Good luck.
