Good point. I’ve only ever serviced my modern cars at the dealer. OEM products should always be used if financially feasible. I only take my non Toy/Lex classic cars to non dealers since GM dealers won’t service a car that’s 15 years old or more. Meanwhile, I took my 1993 Previa to multiple dealers and never batted an eye.
You have to dig into the results and ranking method but usually the most common problems are with infotainment. If users find them more difficult to use then many reported problems often drops the ranking.
Some employees lease them, others buy them, and most of the people who loves cars do a combination of both. It’s hard to know for sure but I would bet that most employees would lease.
For the record, Toyota and Lexus HQ employee vehicles and on-site engineers and mechanics only change the synthetic oil every 10k miles except for the high performance engines (RCF, LC500, etc.). Follow the manufacturer instructions as you’ll be fine. If you drive in extreme conditions or operate the vehicle in high stress situations (off-roading, racing, etc.), you’ll need to change it more frequently than the manufacturer recommendation.
Good point. While I love Toyota, the AWD system that Subaru has in its models is far superior than the hybrid AWD systems that Toyota uses.
