Two injector and fuel system cleaners work: BG BG44K and Redline SI1, both are better than full strength Techron.
All the rest are just naphtha, kerosene, light oil, or worse.
I agree about the oil treatments. These items are not needed if a good oil has been always used and the oil changes were performed on a reasonable interval.The engine internals should be spotless with proper maintenance. Switching to a good full synthetic oil like Mobil 1 0w-40 would be a good idea.
The gas treatments I have no idea about. I guess I've been wasting my money on the Lucas gas treatment I used in my previous vehicles. How is the Lucas gas treatment anyways?
Where can I pick up the BG44K or Redline SI1 at?
