Changing oil type after 90k
 

My Accent has almost 90k on it, and I was think about transitioning to either



a. Full Synthetic

b. Synthetic blend for high mileage cars



as for brand, I was thinking of Mobil 1.



What do you guys think?

Use Pennzoil Platinum (my choice) or Mobil 1 full synthetic oils and an OEM Hyundai filter and don't think about it again. Those are both about as good as it gets. When I was curious I spent a lot of time looking at used oil analyses at the BITOG forums and PP consistently came out excellent. Honda engines did too but I'm not about to switch to one of THOSE! :biggrin: Switching to synthetic is nothing to worry about.
