Attention people wiht cold start problem

[wang540]

My car would not start at all in weather thats below 50F so yesterday i got fed up and for the hell of it bought a fuel injector cleaner. So fast foward to this morning, its 35F and my car started on the first crank with no problems. So i recomend trying that.

Chevron Techron is the fuel injector cleaner of choice for BMW's. Use it right before an oil change for the final tank of gas before you change your oil. Some of the cleaner can wash down your cylinder walls, especially on cold starts, and reduce the lubricating properties of your oil.
Italian tune ups work good too!

Lubro Moly Jectron is better... add Venti Sauber to clean valves too...

I think i used Valvoline, but im not sure. Anyway it worked wonders.

I use the fuel system cleaner by chevron or redline.
