If i put some gas additives into the tank what would the result be? i hear some of these things can damage a BMW engine.

BG 44K

This is all I use and have had zero problems with it. The best way to use this stuff is to pour it in your tank when you are half full and then fill the tank the rest of the way. When you get down to a quarter of a tank left, have a friend follow you to watch your exhaust and stand on the throttle. Dont get a ticket but stand on the throttle hard and as long as you feel comfortable. Your friend should see all kinds of stuff coming out your exhaust. Mostly carbon buildup that is being forced out of the motor. I found this stuff through my mechanic and he HIGHLY recommends it. The deal is you need to use 1 can every 5k miles for 20k miles. It cleans the motor out very well. I saw a motor he was doing a head job on, in a E30....I think it was a '86 model........with 200k+ miles on it and the motor was VERY clean inside. I commented on the cleanliness of the motor and how the owner must take really good care of the car and was informed that I was looking at a motor that had been treated with the 44K, 4 cans over 20k miles.

I have used the STP additives for the fuel injectors and such. It worked with no problems and the car runs a bit smoother after using it a couple of times. I used it once in a full tank then again 2 tanks later.

im using Redline Fuel Cleaner right now. Havent really noticed any improvement but im only at 1/2 tank now. From what i have read this is a very good additive for BMW engines.

i use lucas oil fuel additives. but i use it every once in a while, like after i do a long term of city driving.

yeah all i've used is lucas fuel cleaner. but i think i might try that lubro-moly stuff from germany. i heard its really good stuff.

I used the Chevron Techron stuff once so far & didn't see a difference. It actually seamed like gas mileage went down a little. Probably need several treatments to do the job. I checked with some mechanics & they recommended the Redline or the Techron for bimmers.

ive tried stp and 104 octane booster and only noticed a decrease in fuel mileage but it did feel like my car was a little quicker, i dont know maybe placebo effect

I have used STP and Techron. The stp seemed to work on my gas mileage, but the techron didn't seem to make much of a difference, gas mileage is still shitty (about 19!!!). I am thinking about trying Red Line now after everyone suggested it or that EG 44K stuff.
