Every mechanic has there favorite as far as injector cleaners go but I prefer Lucas Fuel Injector cleaner.
If you run Chevron or Texaco fuel you don't need to worry about an injector cleaner, it has Techron in it and that is a very good injector cleaner. Or purchase it in any parts store. That is what I use.
Like tennishoes, I only run top tier fuel that has additives. I've used Techron in years past with no appreciative results.
My old Tahoe 5.7 Vortec had a injector nozzle that was starting to plug up, kept giving me a misfire on cylinder 5, dumped in a full bottle of Techron and within a few days I cleared the code cause it just felt like it was running better and the code never came back, told the guy who bought it to keep running Techron, that was 19 years ago and I have been running Techron fuels ever sense, and so far none of my rigs have had any injector problems.
Don't put additives in your car- just maintain and repair it properly-
Jamnblues, how would you recommend maintaining injectors without removing them? Wouldn't an occasional dose of fuel additive be recommended as preventative maintenance?
