I would imagine they wouldn’t try to upsell a person who, in addition to bringing their own oil and filter, is also requesting empties.
I drive far more than most and have always ( except with a Toyota I used to service at an independent shop ) serviced all my Honda's at various Honda dealership's and I have never seen them try to upsell a service to me ( except when I buy the car from the sales people ).
The only complaint I have had with getting my cars serviced at Honda dealers ( they are more expensive with labour ) is lately. I had numerous electrical gremlins in my car ( all kinds of lights on the dash, cruise control rpm fluctuating a lot on the highway ) and two dealerships could not find the problem even after several visits ( to two dealerships )and very expensive parts replaced.
They had their most experienced techs working on the car and said they had not seen this problem before. Every time they thought the car was fixed, a few days later, all the lights would come back on flashing.
I told them, surely you can contact Honda Canada tech for help ( Honda must have seen this problem, somewhere in Canada, or the world ) because it's unacceptable to expect a customer to pay for a dealership , who charge more, brag about knowing Honda better than independent shops, to keep replacing very expensive parts but the problem keeps coming back and the cost of the repairs are worth more than the car.
Eventually ,they worked with Honda Canada tech and said ( waiting for part to arrive ) the wiring harness ( major job ) is the problem.
So, none of those other expensive parts had to be replaced ( alternator $2000.00 plus lots of other stuff ) and they said I will get reimbursed.
Why did the customer have to ask why a dealership wasn't contacting Honda Canada tech for help versus doing the parts cannon thing ( Care care nut talks about that ) was very annoying and surprising.
I am pretty sure when my airline has a mysterious maintenance problem they can't fix, they call Airbuis tech for advice.
