Went to dealership for my first "free" maintenance oil change, etc, and it says on the receipt that they used 5w-20 instead of 5w-30, I have a V6
Didn't realize this until I got home. I called the service dept and they said that is what is used in all oil changes and that my truck would be fine.
Should I be concerned? Should I put the correct oil in?
Thanks in advance
I'm thinking i will ditch the "free maintenance" program
