Scangauge setup

What I saw was a kick to mpg right after finishing the pulse and dropping to neutral. This was at peak RPM. The instantaneous would then drop to something reasonable as the tachometer needle descended At that point it would again kick to mpg briefly before returning to what it should show at idle for the speed.

With the feature turned off, I see the numbers blip up a bit at those points, but not all the way to mpg. Coasting down in gear nets me only a few more mpg over steady state cruising because I lack fuel cut. Disagree that fuel cut only works while in gear! Your engine is using the momentum of the flywheel to keep turning.

In a manual transmission car, you save a wee bit of fuel with each upshift because of this! True that the flywheel will keep the engine turning over for a short period of time that could give you the criteria needed for the fuel cutoff. However, the gains from such a short period are fairly minimal, but not to be over looked.

The most fuel efficient method of using the fuel cut-off is to coast down in the highest gear possible for your speed. Shrek , Jan 14, I know that even in cutoff, my ICE uses a minimal amount of fuel.

OK, I'm still trying to wrap my mind around this fuel cutoff idea. Since I've started hypermiling I've just been trying to be in neutral as often as possible because I thought that was the best way to save fuel.

I was willing to sacrifice the additional wear on my brakes. This complicates things. So then if you push in the clutch at this point without touching the gas, disconnecting the engine from the transmission and wheels, you're saying the engine automatically restarts so it can idle and provide power while you're in neutral?

I would think you would notice that happening. Looks like I might have to hook the SG back up and do some experimenting. Is fuel cutoff more prevalent in certain makes, models, or since a certain year? Last edited: Jan 23, Bruce , Jan 23, Shrek , Jan 23, My car does act like it has it.
