I have a 2016 Prius 3 touring, it has about 50,000 miles on it. Our Toyota dealer is recommending an engine cleaning service that cleans the fuel injectors and cleans the engine. I'm wondering if this is worth the $200 that it cost to have done Posted via the PriusChat mobile app.
In my experience, 99% of “dealer recommended” services are scam. If it’s not in your factory maintenance schedule, it’s not needed. There is that 1% when something goes wrong, but that would be a recommended repair/service for a specific issue that needs to be resolved. Just say “no, thank you” and keep you cash. iPhone ?
Dealers love doing that - often it involves in "WRITING $200" on the invoice. TOYOTA have an Injector Cleaner - you add to the tank - we used it on Dad's CAMRY at 230,000km, and it did make a little difference.
I like pj's post. Change that trans fluid with the $200- you just saved and it will look very bad but once you change it then it will be good for the life of the car. Its all the differential gear wear in there your getting rid of.
Should you pay them $200 to do this........that you can and should do for yourself for about $10 ?? Techron is available at any auto parts store and most farm supplys and many big box retailers (WalMart). I do mine once a year.
Correct it uses no pinion gear but there’s still a lot of wear where the final drive connects to the 2 cv halfshafts. I use the term differential for simplicity. I doubt there’s a lot of wear with the sun gear system but where the rubber meets the road much more wear initially. Changing my g2 trans fluid 3 times over 150,000 miles revealed high initial wear at 5000 miles with very little wear after that initial change, Pictures I have seen on this site of g3 fluid looked much worse which makes sense there much higher powered motors. But I still think just change it once at 5000 miles your good to go for the life of the car as it is a pretty prescision trans.
Ok, so I'll just get a bottle of fuel injector cleaner and run through it. I'll also look into the transmission fluid change. I hadn't thought about that. Thanks!! Posted via the PriusChat mobile app.
Prof. Kelly can be seen installing the differential starting at 10:24 in that video: Another view (from Art's Automotive, of a Gen 1): There'd be quite a lot of rubber left behind when turning corners if there were not one.
