Check how many miles per Gallon q

I'm sure this has been covered elsewhere, but yesterday I drove down to 2 miles distance to empty, and refilled w 8.3 gals. I was relieved I made it to the gas station.

Roping in the calories discussion, I needn't have sweated making it to that gas station. That "extra" 2 gals would have gotten me home. But truthfully, I should have refilled earlier than I did, hardly ever visiting a gas station has made me a bit lazy.

 

Was watching a show about the first lunar landing, last night. Noted they had less than 30 seconds of fuel left when they touched down. Made me think of you guys.

 

Yes, I am a bit confused here too! A couple of times I have driven to the "blinking red light" on the fuel gauge. When I filled up, it only held about 8.8 gallons. I always pull it out when the nozzle clicks off! Does that mean, I can force in another 2 gallons? Or does that mean I just had 9 gallons in the tank when I last filled up to begin with? I REALLY don't want to run out of gas!

 

There's a reserve beyond 0 miles distance to empty. I seem to recall others figuring out how far you can go beyond 0. Running the whole system dry is a BAD idea, so I'll be fine w the DTE gauge.

 

They had gravity on their side (1/3 of Earth's gravity? I can't remember) .

 

Lunar gravity is 1/6 G. And they were manually flying that thing. No computer autopilot in 1969.

 

there's about 2 1/2 gallons when the last pip beeps and flashes, and the dte reads zero, not counting ev.

 

The engine is stopped before running completely out. When I've "run out" of fuel, the tank never accepts more than about 10.3 gallons, leading me to believe the Prius shuts down intentionally with 0.3 gallons remaining. This is likely done to prevent sputtering, which would be difficult to manage with the other electric bits that are involved.

Neither.It means you still had 1.8 gallons left when you filled up. Multiply that amount by your MPG and that is roughly how much further you could have gone.

They did have autopilot, but it was headed to an area that looked unsuitable for a safe landing. Neil took manual control to land in a better looking spot. The lunar module still had enough fuel to launch back into lunar orbit, meaning that if all the landing fuel was spent they would abort landing and instead launch back to orbit.

 

good point, and maybe it's to protect the fuel pump?
