Is there a fuel system cleaner that actually saves gas?

not that i heard of ,it’s called “letting off the pedal,lead foot

If your fuel injectors are dirty you don’t the MAX mpg. So AFTER they are cleaned you will get better MPG.

But not during the use.

good Luck…

Lucas Fuel Injector Cleaner saves gas pepboys any auto parts store. and also use there oil or mobile 1

i heard berrymans does

Nope….that’s all money maker crap./

You want to save gas?
Check your tire pressure.
Make sure your engine is running top shape.
Put a new air filter on the engine.
Change your oil.
Change your spark plugs if needed.

These are the best gas savers. I’ve seen guys put two barrel carbs instead of four barrel carbs and saved gas.

The only other gas saver I ever had was JP-4

I got 200 miles out of it with five gallons…….Getting 40 mpg

I would not reccomend anybody using JP-4 that’s some powerful jet fuel and will burn your valves up.

DOES FUEL SYSTEM CLEANERS DON’T WORK TRY PUTTING SOME PULSTAR SPARK PLUGS, THERE REALLY EXPENSIVE , LIKE 25 EACH BUT THERE TOP OF THE LINE SPARK PLUGS AND THEY ILL REALLY REALLY GIVE YOU GOOD GAS MILEAGE GARANTEE
