Bmw fuel system cleaner

Hesitation and start up issues started..... Wasn't sure what the problem was.... Went to bmw and purchased the bmw fuel system cleaner and now the car has great performance and starts right up!!!!! Also, from now on, I will only fill up with "Chevron with Techron".

I did that too to help with the rough idle when reversing or sitting at a light. It helps clean out the carbon build out. Turns out for me it's going to need a new eccentric shaft. The cleaner is helping for now. Warranty wont replace until it generates a fault code.

the BMW fuel system cleaner will probably help all 7-series greatly, but if the idle does get a bit rough and is blamed on the excentric shafts, I'd look into having the whole VANOS system checked out and as well invest in a better oil with some cleaning abilities.

Cleaning the MAF sensor will also be a good idea. Made an amazing difference in both our cars.

@jcharris.... Yes premium... Chevron and Texaco. These gas brands are the only ones that have Techron mixed in the fuel. Also, Chevron rates their gas standards base on BMW's engines performance..

So Chevron is better for our cars than Shell 93 V-power? Shell is much closer to my home than Chevron which is like all the way across town.

I'll have to switch to Chevron or Texaco, I've always used BP b/c they are closer. I didn't realize that brand made a difference when it came to our cars. Gotta treat the lady right..

Yes. Chevron or Texaco is better for our fuel systems in BMW's.... Remember, Its mostly the "TECHRON" that you really want in the gas. The BMW service depts. have the bottle of fuel system cleaner available also . The main words on the front of the bottle is "TECHRON". So definatly for overall performance, Chevron or Texaco with Techron...

Hope this helps!!

Be careful with that lucas stuff! It has a large amount of detergents that can damage sensors and seals over time! Redline SI-1 Fuel cleaner doesn't have that level of detergents but instead uses another compound that cleans without damaging other components! Source: Bobistheoilguy forums

Many moon ago I owned a Ford Crown Victorian and I was an avid Lucas user but I've heard a lot of horror stories lately about Lucas in various vehicles. I'm sure for some it works and others not so much. I'm sure others may have had other factos that caused the gremlins to surface. Anyhow, I decided to go with Redline in my Dodge Charger and honestly I'm a skeptical guy but it seems to have improved it's overall performance. I use to have a small hiccup when punching it heavy on the highway but after adding the Redline it's completely disappeared. Although I've experienced great results in my American Muscle I am terrified about putting any of this stuff in my 750. I've been experiencing a rough idle here and there and was told by an indy that this may clear it up but still.. Tossing and turning on this one fellas, these cars are beautiful yet fragile and EXPENSIVE to repair. Dunno if I wanna take the risk but if I did I'd go with the Redline.

I use Lucas in my Armada but that beast drinks fuel like crazy no matter what you do, lol. Redline seems to be the way to go for the Bmw, just saying....

seafoam is a good product, but it's more of a tool used to clean up heavy build up on the intakes and throttle body and such rather than clean up the fuel tank from the ethanol issues we have.

Top tier doesn't matter when the ethanol in the gasoline is the issue! The extra water retention is causing a ton of build-up and a ton of issues that we wouldn't have to deal with otherwise.
