I have been there a few times. You can do this with any car(in the past) but if you want to engine brake down a large grade it better be fuel injected. Engine braking with a carburetor is gonna blow your exhaust up as soon as you turn the ignition on. Also engine braking will retain your power brakes whether they are vacuum or hydraulic.

Most new cars are so faggoty you can't even do any of this.

I've rolled into gas stations before after running out of gas. Pretty awesome feeling of relief. This was all moreso when I was younger and broke, only buying gas as needed.

I was under the impression that most modern cars use gasoline to lubricate the fuel pump and if you run out of gas completely then the fuel pump is fucked. I've never put it to the test because that seems like it would be a really stupid reason to have to replace the fuel pump.

Typically if the computer sees no engine RPM it won't activate the fuel pump. So basically running out of gas won't kill the pump. Also in the scenario I was describing the computer isn't even on. Engine is spinning but no one's home.

I've done it on motorcycles. I coasted down the better part of the smoky mountains to hit a gas station on a honda f4i when I was barely 18. It was actually kind of cool to hold 45-55mph mile after mile while coasting in neutral.

Thank fuck my motorcycle has a secondary emergency store of fuel. I've accidentally ran out a few times on my college commutes back in the day.

I love the look on someone's face when you show them how the reserve works. Even better is when they don't know it exists, you show them, and then you realize they've been riding in reserve the entirety of owning their bike. None of the crotch rockets I used to ride have a fuel petcock. The "reserve" is automatic and consists of a few blinking bars on the display. My Ural does, and I've had to use it a few times.

The "reserve" is automatic

Well that's just dumb and defeats the entire purpose of one. You need that "oh shit" moment when you run the main tank dry. And it makes more sense to have a manual knob/lever/etc to force you to acknowledge your mistake.

I once ran out of gas and coasted 2 blocks into a gas station down hill and got a pump spot.

steering wheel was hard as a rock and breaks almost didnt stop me

The Bosch D-Jetronic fuel injection (VW, Mercedes, Volvo roughly 1968-1974) would turn off the injectors when the throttle was closed and the RPMs were above 1000. Lift from the throttle and coast to a stop using zero fuel until down to idle speed. An interesting side effect was if you tried to set the idle too high it would race up to the fuel cutoff RPM then die until it reached the low cut-in point, hunting up and down continuously.

The worst is mechanical gasoline injection. God I hate it. Over time the plethora of diaphragms, springs, poppet valves and other fuckery all wear out. Basically have to replace everything.

Mechanical diesel injection on the other hand is tits. Not tons of power but that shit will run forever. Until you run out of diesel. Then it's a bitch.

Edit: If I ever have to look at one more microfiche I'm gonna loose it.

You talking about the mechanical pumps like of some of the MB (and Alfas?) in the late '60s? I've got 200 k miles on my 67 MB pump with no issues. Bosch K-Jet (CIS) works well too if the fuel is clean. Agreed, diesel is great as long as the pump is kept clean inside.

I'm talking about Bosch mechanical gasoline injection. Not the pump. Essentially the air flow meter which is just a large plug on a stick opens little slits allowing for more available fuel. Than there is diaphragms and regulators and adjustments and vacuum bullshit up the wazoo to fine tune it. It's a fucking nightmare.

Edit: Yes K-Jetronic falls in this category.

Growing up in a very rural farming community, we had all been driving tractors since we were at least 8 years old, so around 14 years of age, we all would have at least 1 car. My friend had an old VW, he cut the fenders off it and called it a "baja", LOL. The fuel tank is behind the dash, in the front of the car. His fuel gauge was broke, so while out 4 wheeling at the local rock quarry, he would speed up to around 20mph, we would stay very quite, and right before rolling to a stop he would slam on the brakes. By being very very quite, we could hear the fuel sloshing in the gas tank. That is how we knew if we had much gas left.

in neutral before, never had the balls to turn it completely off. and yea i remember those young heady days of buying enough gas to get me to the party. only time i ever ran out of gas was in a town state renown for police profiling teenagers and planting drugs when needed, with 2 of my friends and a gram of coke. luckily another friend was wiling to make the journey to us with a gas can and get us out alive, it was a miracle we made it out without seeing a jew golum(pig). those where the days when only having fun was important, compared to these days where all that matter is the future of my people and the freedom we took for granted long ago.

Yeah if you turn it completely off you better damn well know what you're doing and how your car actually works. I'm not advocating doing this. Just that I was confident enough to do it because of my car knowledge. If you're not careful you could turn the key to the "Lock" position instead of "Accessory".

Then you crash.

I've been there, my car is manual so I didn't have to burn up my starter everytime I did it. Turned it off and back to accessory so the wheel wouldn't accidentally lock up, always when I was going straight, and my gas tank would last 30-40% longer.

Some newer cars fuel injected age and newer, mid/late 90s and newer, will turn off the fuel injectors as you coast downhill when the torque converter is locked in the higher or highest gears. It is seamless on your end as the engine is turned by the wheels spinning.

The way to see this is to have an OBDII display which can show your calculated fuel mileage or the fuel rate.

Indeed. I should have clarified in my original post that this is moreso related to manual vehicles. But it can still apply to dumber automatic vehicles.
