'21 Forte FE 6-Speed
Yeah I’ve never run injector cleaner or oil additives through anything I own, both new and old, some with well over 200k on them.Ok I can’t tell you what to do but... I run my commuters to almost 200k within 5 years and never... NEVER .. do the flushes, brake, injector back flush blah blah blah... if it’s going to break it will break.... flush or not. I have less car problems than anyone I know and I don’t do anything other than general maintenance. I think all the odd additional services is just false sense of security..
I flush the brake fluid but that’s because I don’t trust old fluid to not boil when I’m driving my stuff hard. It’s cheap insurance and I’d rather not risk failed brakes when ripping it on back roads over saving like $40 every few years
