The car says Castrol 5-30w SAE. Couldn't find a synthetic designation anywhere on the car or in the manual, called the dealer and they said use 100% synthetic. Anyone know different?
Manual says 15 or 16,000 miles, or 1 year. Dealer told me to do it at 7500 or 1 year.My dealer wants me to come in and change my oil at 7500 miles.
