Fuel Injection Cleaner

any recommendations, and at what miles should this be considered, if at all?

 

Not recommended on the D4S engine, if you are to use one, use the Toyota injection cleaner. I personally will not use it on the D4S unless I find an issue that is difficult to resolve. I wouldn't use it as a preventative.

That said, its still a good idea to use a water separator in the tank depending on the humidity of where you live.

 

I'm in the high desert area of socal so humid....nope, seldom gets to 30% unless its raining.

 

I have used Lucas in the past, why would you not use anything in this engine?

 

just curious if needed, I read something about a self cleaning cycle but I think that was referring to the valves.

 

your ahead of me I never read that. so until I read it I will not use anything else I guess.

 

so injector cleaners are more....snake oil than anything else, at least thats how I read that.

 

Snake oil, all of them and always has been

 

I've seen injector cleaners work, but more as a diagnostic tool when the injector is clogged, or a valve is gummed up.

That said, you need a true injection cleaner, one that directly hooks to the fuel rail to work. Any tank cleaner does not work as it is far too diluted.

Next this system is a sensitive direct injection system with side ports that only get used 50% of the time. Toyota doesn't want us running fuel injection cleaner into the secondary fuel pump.

I encourage people to do a true cleaning once you're over 10 years old and 100,000mi/160,000kms but on a new vehicle its a waste of money.

 

I was under the impression that the V6 has an auto fuel injector cleaning thing which is when you hear the engine ticking at low RPM??

 

"We started our drive in the 2016 Tacoma by taking it on the roads near Tacoma, Washington. Our Double Cab is powered by the new Atkinson cycle 3.5-liter V6 with direct and port injection (Toyota's D4S system), which has a self-cleaning feature to remove deposits from the high-pressure fuel injectors."

(and, probably, other places)

 

if you must,red line si-1 is the best stuff

 

Tad off topic but Heet is some good stuff. I had water in my tank 2 weekends ago in my 4Runner. I was 150 miles away from home, it was 0 degrees, and it just wouldn't start. Put some Heet in it and it eventually fired up
