I read a post here not long ago about some folks experiencing hesitations on acceleration and flat spots. I have been getting these on and off for awhile now and have noticed a slight decrease in performance recently. Cars been to the dealer about it but no fix. I use 93 octane and have been using octane boost and cleaners regularly. I even ran a half tank of 105 race fuel to clear everything out. With direct injection I doubt the cleaners will do much good and I still haven't seen much improvement.

Someone mentioned they used sea foam and it worked quite well. Could someone point out where to pour/spray the sea foam into the vaccuum line on a 328 N26? I don't need an argument about sea foam I just need someone who's successfully ran the cleaner through the intake to chime in for me. Thanks guys!

I guess I didn't understand. If you put it in the gas tank, wouldn't it travel through the injection system. I've used it and I'm a believer for sure.

At first that's all I did too to clean the system but the hesitation wasn't getting fixed, it cleans the tank from humidity, bad fuel ect. so by the time it reaches injectors it's already clogged from the tank and dissolved in the fuel maybe idk then I tried the injection cleaning from intake and 80% is gone.. I still had a hesitation problem at idle when the car is warm :/
Then I took the risk and cleaned pcv valve but I didn't use seafoam, then all hesitation was fixed

Guys as far as Sea Foam goes, is there a maximum recommended frequency of use?
With their recommendations, 1oz per gallon means 1 full bottle for the car's 60 Litre tank.
How many KM's between uses would be recommended? Once every oil change makes sense, but I don't want to overdo it if there can be potential harm to gaskets, rings etc.. (even though their product literature says it's safe for those components).

Mostly recommends every 3 k miles but I prefer every 5 like before every oil change to be safer

Thanks.
BMW's oil changes are obviously further apart than that so maybe I'll stick with that to be safe.

FYI, SeaFoam fixed my hesitation. Put a full can in 1/2 tank or so.

I use Castrol Edge avg. 9 k for oil change so I do it 2 times on half which is only through tank and before oil change the rest like pcv valve.

I just put 1 bottle in each of my 2013 328x and my 2008 528x. Let's see how it works out.

you have to be at half to quarter empty to feel the difference

OK. I just went by their suggested 1 oz / gallon concentration.

Just to be clear, I pour the whole thing in the tank when I'm at half empty and then dry to empty. I though you pour the whole thing and fill up.

yes that's what I do, I pour then dry to empty then fill up with good fuel maybe an octane would help too
