I got my last free TGMO 0W-16 SP oil change at West Coast Toyota of Long Beach today. They are one of the better dealers in the area for service. The car was at 17,091 miles and two years. Strangely, they recommended both engine air filter and cabin air filter changes for next time, with less than 20,000 miles on the car driven on urban roads—just in time for nonfree service.
I will simply by the filters from the dealer and do it myself if necessary, which would cost me $60.05 ($14.93 + tax for engine air filter and $39.54 + tax for cabin air filter at the same dealer) instead of $115.33 as they quoted for that work and be done right for sure.
