I had a Honda Odyssey serviced.
Normally they recommended every 6 months service, but many expert/ mechanic mentioned if using a 0W-20 engine oil, you only require to service every 12 months or certain kms.
So I service my car 12 months after, the report stated they use 10W-30 or 10W-40 which the car need to be service every 6 months. I ask the service center and they said the manual is for Japan, Australia condition is fine for non premium 0W-20, and they said to maintain my 3 years warranty, I need to service it every 6 months regardless of premium oil or not.
Today I call up for a service schedule (6 months), and requested I use my own 5W-30 than their lousy engine oil. The service center said all odyssey is using 0W-20 why you want to downgrade the engine oil ?
I was like…… what the? meaning the use the wrong engine oil for my car 6 months ago?
Dodgy service provided by Honda…..
My friend demanded that I request for free oil change from the service center, but the labour cost will still be around 370+ compare to Autobahn around 200+
Any expert could advise me what to do next?
EDIT: change the W on the right position, has confused a few people.
I can hardly understand what this story is about.
Using not recommended/alternative oil doesn't change service interval (especially for warranty purposes) in 99.99% cases.
The other thing that worries me is that you have 4 oils for very different temperature conditions in your topic and seem to think that bigger number is better.
