Default How can i clean my fuel injectors

Toyota technication told me that i need to clean my fuel injectors due to being dirty, they are charging me over $120 to do that. Is it hard to clean them? and what about power steering flush, there also charging $100.

If you use name-brand fuel you are getting a ton of detergent in every tank. I add a bottle of off-the-shelf injector cleaner to my tank at each oil change. There's no need to pay a dealership to do essentially just that. Sometimes they get fancy and use a drip cleaner into the upper intake manifold, but it accomplishes the same thing and still isn't worth $20, let alone $120.

The PS flush is a good maintenance item to have done, however. They should hook it up to a machine to completely flush the PS system.

Lucas Oil deep clean. This was the first product of theirs that I tried and within a week I had seen 1mpg back. Now the whole truck is running lucas including fuel treatment, diff fluids, trans, all my oils and the stabilizer etc etc. Overall, I've gained back 3 mpgs highway and the truck honestly feels better, the ticking in the motor went away completely which was pretty crazy

Try the Deep clean first then run a medium sized bottle of the fuel treatment through it.

Just to clarify, you mentioned a technician indicated that the injectors need cleaning? Are you experiencing any driveablility issues such as poor performance, rough idle or poor fuel economy? Or was this a service advisor trying to up-sell you?

I agree with Mike and SDHQOR there are plenty of effective products that you can use to clean the injectors as a diy project. Also remember that injectors and valves get dirty over time, so use a good detergent gas and over time it will reverse itself.

Yes the tech recommended the cleaning of the injectors and throttle body and the truck been wasting more gas and feels kind of sluggish.

so has anyone really cleaned their fuel injectors by taking them off and cleaning them or just run fuel cleaner through the system?

I just add Lucas fuel treatment every so often.

Wife's X5 was throwing codes indicating a sticking fuel injector. Adding some Lucas to a tank of fuel was all it took to correct the situation. No more codes...
