Fuel Injector Cleaning

[Jager]

I would like to think I am maintaining my fuel systems, heck I get well over 250,000 miles on my cars. My Boxster has over 228,000 miles on it and other vehicles I have owned have clocked many more. The only gas I put in my vehicles is Mobil or Chevron (with Techron). I will even add an injector cleaner to the tank once in a while but the V8 injected motors seem to need more than just a cleaning additive in the tank at some point after 120,000 miles.

So JFP, have you ever used your cleaning system on a Boxster?
