I like cleaning my Throtle body and fuel injectors every oil change is this bad? After I'm done I add Mobil 1 complete fuel system cleaner.:confused:

I use Chevron's Techron every 5K miles. Techron states that it can be used every 1K miles. I would check the bottle for Mobil 1 and see what its recommended interval is.

If you use quality fuel this is not necessary.

I always use 91. Each time I clean my throtle body it is always dirty.

WHat does your air filter look like?

Yup. Not bad, just a waste of time and money. ;)

Dirty is fine, buildup isn't. You shouldn't see significant buildup. If you do, then you clean.

This may well be true, however, on my last car, I put 237K miles on it and never had an injector issue while several others I know did. If it keeps you from having to have new injectors put in, or your existing ones cleaned, it is money well spent. If not, well, for me, it is the price of piece of mind.

Try seafoam...... I use it on my VW's....
It makes a smoke screen!
