Pointless in making an appointment for an oil change. An oil change should take 20mins max. Not 2 hours. I made an appointment 3 weeks in advance for our Vans first oil change. Their website stated it was $34.99 for an oil change. After the 2 hour wait and about to pay they tell me it's $50.00 . All new Honda's only use OW20 full synthetic. That's wonderful I will do my own oil changes next time and it will only cost me $20.00
