    You don't need to go synthetic. If you do some research, you'll find that most of the cars with crazy high miles on them with original engines, do not use synthetic oil. Not saying that synthetic is bad. It is actually better because it lasts longer between intervals. The thing is: If you continue to maintain your car properly, you'll be fine without synthetic, plus you'll save quite a bit of money too. Look at synthetic as added insurance. What are you running now? If it's not burning oil, continue using that. I have a 1999 Toyota Camry with 277K miles on it and it runs great. Nosynthetic oil here!

    If you are using conventional oil you better be changing it every 3,000 miles and be checking it every 1,000 miles and topping it up so you never get lower then half way between the upper and lower dipstick marks!

    Always fully synthetic. The mileage is irrelevant as fully synthetic protects the best and resists burning.
