Is BG44K fuel system cleaner recommended or not?

 

no!

 

Can you explain the detrimental effects of using BG44K in an FD's fuel system? I'm curious to know why it's not recommended. I don't know much about rotaries but everyone with piston engines swear by this stuff.

 

Yes.

A good friend of mine who has worked on Mazdas for 20 years reccommends it. He had 10 years factory training at a Mazda Dealer, and another 8 years working on FD's (and other cars) since. I ran a bottle thru my car with no ill effects. I can't say for sure that there was any benefit to using it because I did a tune up at the same time. The car ran great afterward.

I use it about every 6 months and I have had no problems with it. My compression at KD was excellent and my injectors were perfect when Dave checked 3 months ago. I wouldnt use anything else. I have heard great things about it and nothing negative. A lot of the other additives dry out the apex seals.
Just my .02. Good luck.

 

I don't have an FD but I used it for my A4 when I had a rough idle problem. My idle problem was so bad that I stalled my car many times at parking lot. Initially, I was thinking about cleaning the idle control valve in my car but I decided to give it a try and guess what? my idle problem disappeared right away. I guess it cleans up all the fuel injection system including idle control valve.

 

I always heard that BG44K was THE cleaner that you wanted to use over all other cleaners. I need to pick some up, anybody know where to get some?

 

CYM - go to http://www.bgfindashop.com/ to locate your nearest dealer. A local mechanic sells the fuel additive for $15/bottle. I didn't go shopping around for price though.
