Adding fuel system cleaner?

[dhagopian]

Is there a trick to pouring fuel system cleaner into the X3? I put the bottle in but I don't think anything got in there and it just made a mess instead. Was the tank just too full or is there a trick to getting it in?

You have to make sure the next of the bottle pushes on the flap inside the fuel tank nozzle to open it, otherwise it will make a mess. Don't worry, you won't break it. Just jam it in there. It will feel a little stuck but you can pull it right out. Add the bottle when you go to refuel an empty tank for maximum mixing and benefit.

i use a piece of plastic pipe to open flap before filling cleaner . bmw dealers sell german made cleaner which has perfect nozzle on bottle so now i use that bottle to fill with other cleaners.

Yeah I think the bottle just isn't made to fit in there enough to push the flap open. Maybe a good idea to get the BMW one and use the bottle. I'm trying to use the Redline cleaner, but I think the neck is a little too fat to push in very far...

BMW cleaner fits perfectly. Don't know about any others.

I have used RedLine before and from what I remember, it fit just fine.

Don't waste yourt money buying the BMW fuel system cleaner from the dealer. It is Chevron Techron with a different label. Go to Chevron or most local parts stores and pick some Techron fuels system cleaner up

You are correct about the branding. However, with a BMWCCA discount I've found the dealer to be cheaper!

That is another way to go. I am also a member, but some of the dealers in my area don't honor the discount anymore, so I just go to the local parts store.

Well I should have waited longer and read this before I guess but I did get the BMW one earlier and the bottle worked perfectly. Problem solved. Thanks for the responses.
