BB, I'm going to call you Kramer from now on...haha Don't do this! Crap that gets in our tanks can be sucked up...prob not but not worth the risk.

 

I've read also that that was a myth about sediment and empty tanks. Especially for cars built since the fuel-injection era. The explanation is that fuel gets pumped from the bottom of the tank no matter what, so if there were sediments or contaminants in the tank they'd go in no matter what the fuel level.

So cars have screens and fuel filters to keep the sediment away no matter what. Also, the fuel tanks are built with 1000x more rust-resistance than they used to be, which keeps most of that crap from getting into your tank in the first place.

However, running it completely dry can shorten the life of the fuel pump. Allegedly.

But I wouldn't risk it either way.

 

LoL!!!!!!!

 

Now does this err on the side of caution apply for most vehicles?

You would think so but who knows. the amount of peopel you see on the side of the highway with no gas is crazy in missouri. any info on this?

 

You are correct. That's dated information. There's no "crap" to be sucked up by using the last of the fuel in the tank. Maybe this had some degree of validity many years ago, but certainly not on modern cars. There's a sock type screen and an in tank fuel filter in our cars to alleviate any moisture from the fuel or foreign particles from being introduced into the engine. There is no damage from using the last fuel in the tank. It's not good for fuel injected engines to run completely dry, but that's the only danger of using all the fuel in the tank. They this old wives tale persists.

I've seen inside my fuel tank twice. Clean as a whistle.

 

On most modern vehicles, the fuel gauge is actually made to show you slightly less fuel than is actually in the tank as a "fudge factor" to keep folks from running out. When was the last time you drove any car that the gauge didn't actually go below the "E" mark? Some go way past here with fuel still left.

I've been driving Nissans since '91. Every single one has more gas than the gauge shows. So has every other car to varying degrees. The distance to empty is just to let yo know you need gas soon, it's not particularly accurate - at least not on these cars.

 

Thanks BB

 

Referring to a older comment, our tank is actually pretty close to 20 gallons. I've seen a G fill up 19.xx gallons. He was pretty brave to have gone that far.

The worst thing about that gauge is the one in the center console lcd and the one in the driver dash don't agree with each other. And when the warning light comes on the display in the lcd goes to '*****' which is completely useless.
