Chevron Techron Recommendation?
 

I read in several posts that chevron techron is a good cleaner for my fuel injection system. Since chevron makes four different kinds (blue, red, yellow, and green), Would someone tell me which is best to add to the gas tank, and which is best to pour down the air breather to get that part cleaned?

I used the fuel system cleaner, seems to work pretty good. Smells like hell after you leave the gas station, but other than that, seems to work as promised. Remember to dump in it when your gas tank is near empty, and then fill the tank up all the way.

I use BG44k twice a year, and techron twice a year.

BG44k is like techron X10

I use the Techron Fuel Injector Cleaner. Specifically that, instead of the Fuel System Cleaner. Works quite well.

It is recommended, depending on how dirty your injectors are, to change the oil afterwards.
