Catalyst Injection System...Does it work????

Slowing down will save you money too.

That's like so low tech!

I would think that the initial spike is due to cleaning the combustion chamber by de-carboning it, to include injector nozzles and once clean, the engine normalizes. It is like high flow air filters, the volume of air in normal driving conditions will never require the volume available, and therefore, no significant benefit other than believing you have more power.

Sounds more like a placebo.

Scott, you hit it perfectly. That's exactly the reason they
gave me for the milage spike in the beginning.

I think both Scotts nailed it. Why not buy 3 cans of Sea Foam, dump one in the crankcase and two in the gas tank. Goodbye carbon build-up. The Sea Foam probably won't give you any significant mileage increase, but if you believe it will, well... Paying $20 for 3 cans of Sea Foam won't have near the same effect on your subjective perception as dropping big bucks on the high tech Catalyst Injection System.

My van at 400k gets better mileage than it did at 40. Never had any type of injector cleaning, decarbonization, or hocus pocus.
Gas engines run clean these days. Some lament the days of points and carbs. Not me.
