Fuel Injector Cleaner

[uplusd]

Ran a search and only found threads about dealer's trying to convince people they need to the dealer injector cleaning service, basically BS.

But I'm wondering if anyone uses this stuff in their M3? I have a few bottles laying around the house, might as well put them to good use.

I've run it ever 3k miles, usually 2 tanks back-to-back on all my cars; but not the pro guard. I run the concentrate plus.

I run a bottle of techron through the tank every so often. Keeps injectors clean and helps carbon deposits from forming on the valves.

FYI techron is exactly what BMW sells except its re-branded and costs more.
