Fuel Induction cleaning/ messing up turbo?

[bowman316]

I called a shop inquiring about fuel induction cleaning/fuel injector cleaning. and they said that since I had a turbo, that might mess up the turbo.

I have been getting poor gas mileage lately. down from 31 city, to 27 city.

Will cleaning out the injectors mess up the turbo somehow?

Dont bother doing it, just a waste of money. Run a bottle of Techron fuel system cleaner through your car and only run Top Tier gas. I have multiple 100K+ vehicles that have never had the injectors "cleaned" as I run Top Tier gas and Techron every 5-10K.

Also clean your throttle body

You can do an induction cleaning on a turbocharged car, they don't like to though because sometimes big chunks of carbon come out and hit the turbo impellor. If you drive it like you stole it all the time and use decent gas, you will never get carbon buildup.

You know when you see grandma get on it in her Ford Crown Vic and that puff of black comes out? That's carbon build because grandma doesnt hit the pedal hard or often enough.

You have to watch it with fuel injection detergents; alot of our systems are made of plastic o-rings and fittings. Some detergents dry out plastic and can cause more problems than it's worth. Just make sure the fuel cleaner you use is plastic safe. If your not sure; get a piece of plastic and put a couple of dabs of the cleaner you want to put in your car on it. If the plastic dries out; I would not put that in my fuel system.

how do you clean your throttle body?

Techron works well but if you can get 44k much better. Google it.

 

[bowman316]

Is the throttle body right above the turbo? Is this it? I had a brown stain coming out of the small hole, and running down towards the turbo.

 

[BradF80]

That's the intake side of the turbo, not the throttle body. a little brown is ok. The turbo uses a wet float bearing and oil naturally seeps past. When you have a lot of oil you have to worry.

so where is the throttle body? other side of the turbo? looks like I would have to take the bumper off to access it.

I've owned many cars, both fuel injected (throttle body, sequential etc) and carbureted and I've yet to do this to any of them.

In fact to be honest, I've never seen a cure in a bottle either. Any time I added something to the tank it never fixed an actual problem other than my wallet putting my hips off kilter.

What I have seen work is either tearing the carb apart and rebuilding it and cleaning it by hand, or with injectors replacing them.

I have heard about people having issues and needed to clean the throttle body, but once again there's no solution in a bottle that you can just add to the tank.

BTW, on one of my previous vehicles I got 190,000 out of a set of injectors all on the cheapest fuel you can find and the only reason I replaced them was it failed emissions.

Have you checked your tire pressure lately? That'll kill gas mileage faster than almost anything, not counting driving habits.

The throttlebody is on the back-driver side of the engine.

TB's are a very low-maintenance item. If they actually need a cleaning, it's because something has gone wrong elsewhere. A little bit of oil is completely harmless and won't need more than a paper towel to mop up.

yea, tire pressure is fine. i keep em around 37 psi.

Idk, maybe i just need to get used to 36 mpg at 70 mph.
does that sound about right. 35-36 mpg doing a steady 70?

My average has never been less than 39MPG with a mixture of stop and go traffic, some cruising at 50 and a lot at 70.

I do 45 mile trips though and cold starts really hurts your mileage as does hard accelerations.

There are a lot of variables so yours could be completely normal.

When I go to my parents house which is 100 miles with a lot of hills my mileage drops a lot.
