Dealer Fuel injector cleaning service
I know this is discussed before, but I didn't find anything relevant other than the fact that the we should use techron fuel additive in the search I did.
Took my car in for service and they recommend the Fuel Injector Cleaning service for $190. I asked them do they remove the injectors, they said no, they run an alternate fuel line into the injectors to soften up the build up and put then put the additives in the tank. has anyone done this at the dealer and notice any difference? Trying to see if it's worth the $190...I've been using chevron for a while and running the fuel cleaner from Costco chevron cleaner. Please chime in. Thanks. |

They can recommend a million other things as well....but the main question is whether or not you need it.
Have you been noticing rough idle conditions? lower MPG? Loss of power? If your car is running fine then the service is not needed and just continue to run the Techron every 3-5,000 miles. |

And I have been told not to use it more than that as it will begin to break down your motor oil.

No rough idle that I'm aware of...not sure about hesitation... but if there's carbon build up... you never know until it's really bad. My MPG is about the same...I get about 2 to 3 more MPG when I have the bottle of Techron in...other than that...I get about 190 miles per tank in the city.
But I wanted to know if the dealer injector service is any good or it's the same thing as them throwing in a bottle of techron for $190. Thanks for the input though. |

I think it's snake oil, man. Just try and use good fuel and run techron once in a while. Unless you have over 100,000 miles on your car, I wouldn't even worry about fuel injectors.

Out of curiosity, would the Techron fuel additive show high lead content in an oil analysis? Reason I ask is because I sent an oil sample to Blackstone labs and they came back and told me the lead content was 57 PPI compared to the universal average of 3 PPI.

My last Blackstone I did(and first on coupe) had a 53 on lead. Im pretty sure this was caused by racing fuel from previous owner or contamination in the oil from the BMW tech who sampled the oil. Not too worried as it could be many things. Will sample again in March but curious as well about Techron as I put some in before the sample was taken.

I'm about to send in a sample, so I'll report the results.
OP: how did they determine that you need this fuel injector cleaner service? |

I was curious about the cold weather cranking...takes about 1s longer...he said it was normal... but Cali gas is cheap and they say that the SIB is to recommend cleaning the fuel injectors for customers to queries about any hesitation or gas related. He wasn't pushing too hard. He's a good service adviser... I"m sure he has to sell some, but pretty up front and great service...so I'm not going to say anything bad.
I was just curious if what the dealer did really worth the money. |

Unless you're experiencing hesitation, check engine ligts, bad throttle, etc I'd suggest you run a cleaner in your tank. Just make sure you do it AFTER you get a sample for Blackstone and BEFORE you change the oil (like the last tank of gas before you change the oil). No sense in changing the oil then running the caustic stuff through your fuel system and letting the stuff get into the oil.
I am a believer in the Chevron fuel system cleaner as good maintenance. If you really want to clean the injectors you can take them out and send them here: http://www.lindertech.com/inj_faqs.htm BTW: If you're getting a rough idle the sparkplugs would be a cheaper way to swap. A worn plug can really make a rough idle. And the BMW "lifetime" plugs are a joke, yes they're good plugs, just not 100k miles good. |

I've been running chevron gas for quite some time now and I also put the costco chevron gas cleaner as directed. But I wanted to see if anyone actually had the dealer injector cleaning service performed and saw any difference...that was my original questions.
I just want to make sure my cars are always in prime condition that's all. I thought about new spark plugs...but my car only has 25.5K miles on it. |

FYI: I changed my sparkplugs at 24k since I bought my car used. The old ones looked fine, but after I put new ones in the idle was much smoother. From Tisher or BavAuto they were big bucks, but only $6 from Kragen's. So for under $40 you can only improve throttle and idle. Don't forget a little anti-sieze on the threads.

My idiot dealer just tried to sell me a $189 alignment, because it's supposedly on the "maintenance schedule" to be done every 15k miles. Really? BULLPUCKY. Alignments are done when needed, not by mileage. And my local frame & alignment guy, who does the job RIGHT (I've had horrible experience over the years with stealership alignments), charges LESS THAN HALF of what these knucklers want to charge me. I REALLY resent that kind of up-sell - pure out-and-out lying with the "schedule" claim. These are the same retards who admit to putting 40 psi in "all" tires of "all" cars that they service, despite the fact that it has no relation to the individual pressures called for in the individual cars. This visit the idiot SA told me that they do this because so many cars come in underinflated and many people don't bother to check, so this is like some kind of favor they're doing them or something. Really? I wonder if their lawyer knows they're doing this?? Idiots.

Hi, My idles are not rough... I was more curious than anything. In non Sport mode, it seems a little slow...but it could be just the computer...I need to do the reset trick I believe... In non sport mode...which I don't drive in that much it seems fine. So I'm not sure if the spark plugs are needed. If I was keeping the car, I would get it chipped...but I wanted it stock and under warranty...so I never did anything with the car, other than put OEM strut bars.
Far as alignments go, I've had several dealers say the same thing, that these cars needs to be preloaded before the alignment is done. I guess they fill up the car with sand bags or something and then do the alignment. I had a little vibration in the steering wheel above 70...I wasn't sure what the problem was...They told me $120 for balancing all 4 tires. I knew was getting robbed...but for me to go to my alignment guy and do it...it cost that much in my time...so I just paid the dealer to do it...seems fine now. There's a lot of upselling done everywhere...even my dentist does it...offer me a $35 fluoride rinse...did nothing for me...said it could be covered under insurance and billed me afterwards....needless to say I no longer go to that dentist. Far as the Service Advisers are concerned. The one I have in SoCAL is the best so far of the 3 places I've been. I don't recommended Bob Smith nor Valencia...in Los Angeles. Valencia fixed my car and I had to fix it myself afterwards. |
