When should I do a fuel-injection service?

My ‘18 runs great but while getting an oil change the tech tried to upsell me on a FI service. The truck only has 35k miles. That said, now I’m left with the question: when do you do a fuel injection service?

 

Never.

 

The correct answer is never. Unless your fuel filter clogs up, which will likely be never.

 

I wouldn’t before 100k. The dual injection allows the injectors to clean themselves. This isn’t like a non Toyota direct injected motor

 

Awesome thanks!

 

Throw in a can of Gumout or SeaFoam and call it a spring.

 

I do use a bottle of this every oil change (every 5K miles for my 2nd Gen).

 

Same I use that or the Lucas.

 

If your truck has not started getting less fuel mileage and seems to run as good as always , NO . As long as you use top tier fuels you should be fine . If you want to sleep a little better at night , add some Techron or Seafoam to the fuel a tank full before each oil change .

 

Also, if your mileage is slowly dropping, then maybe a good cleaning of the throttle body and MAF sensor. It made a noticeable difference in my 2006's mileage and "peppiness"...(quicker response)..

 

Never,waste of money like others said.

 

So...how do you do that??

 

Search it here. there are many threads... I only did my 2006, not the 2016 yet......

 

What about when using cheap gas?
.....I’d assume the fuel filter would catch any particles.

 

I dont think Injector cleaning cycle means it cleans the injectors, but rather the backsides of the valves.

 

with these direct injections, never. just use top tier gas when you can.

these engines have a self cleaning feature at idle for the injectors. it's mentioned in the manual. perty cool.

 

Two bucket method...
