Fuel Injector Cleaning?
The car is visiting the dealership for an oil change (since I'm not mechanically inclined at all and don't have the proper equipment) and they asked me if I'd like to have my fuel injectors cleaned with a high pressure injection of some sort to clean all the carbon build up out of there, supposedly it increases performance and gas mileage, however, I'm thinking all they want to do is line their pockets with my $150 and its just snake oil, so I'm thinking its a waste of money. The car runs great and doesn't feel sluggish at all, but they suggest it.  What do you guys suggest? | | Reply » Fuel Injector Cleaning? |
I believe this was discussed many moons ago by some people that were pretty smart on the chemistry of modern fuels. Now I'm curious to see if I can find that thread again...
From what I remeber being discussed here and things I have read elsewhere, if you are using high quality, name brand fuels (Shell, Phillips66, Texeco, BP etc) there are plenty of detergents in the already which should keep the injectors pretty clean.
If it's any consolation, I ran my E46 323i for 7+ years and 120K miles and never used any injector cleaner or had any like service performed. When I sold it, it was getting BETTER gas mileage than when new, and performance had not suffered at all. The 'ole gal ran like a charm.

I get it for 15 cents cheaper than Shell or another comparable top tier retailer! But I think the engine is fine, it gets opened up every now and again and it runs great, sometimes though on start up, its a little rough.

Just add a can of BG 44K every 10K miles or so to a ful tank of gas. http://www.bgprod.com/products/fuelair.html
That's all you should ever need if you use a top tier gas. http://www.toptiergas.com/index.html

Don't bother with the dealer service. Just use good quality gasoline, and I even think the Techron formula that Chevron uses is available for sale as a concentrate at any auto parts store.
The only time I would really worry about serious carbon buildup is if you drive frequent short trips only, especially in cold weather.
