My 2017 Hyundai Elantra manual states to add a bottle of injector cleaner to the tank something like every 10k miles, nothing about taking it to the dealer for an injector cleaning service. I may be off on the mileage, but it is in the manual. I live in Ohio and run 5W30 year round. I have been thinking of running 10w30 in the summer months though. May start this coming summer.

I'm not happy with the dealer because: [list] [*]At my last visit they strongly recommended a $200 fuel injector cleaning for my Kia Sorento with 40K miles. They said check your owner's manual. I did and it wasn't there (which I expected). [ Oil recommendations from the owner's manual: 5W-20, 5W-30, 10W-30 API SM / ILSAC GF-4 or above. Thanks.
