Default What do you do, if you don't run your car out of fuel ?

I have read some threads on here that say not to run your vehicle out of fuel, and I can see why. But I might only run my car/truck maybe once every other week or so. So should I shut the vehicle down by blocking the exhaust and leave it sit with a little fuel in it ? I have read that letting it sit with fuel isn't good either because it will gum things up. How do you leave your vehicle sit when your done running for the day ?

It all depends on when you expect to drive it again. If it's going to sit for more than a few weeks, then drain the tank and fuel lines at least. I generally run mine at least every 2 weeks so leaving a little fuel in the tank has not been a problem for me thus far.

I always shut off my engine by tapping the flywheel as well...and putting the piston at BDC when I'm done.

I dump mine at the end of the day and blow out the fuel lines. I always stop my motors by covering the exhaust. I dont like the sudden stop the fly wheel method causes. just my 2 cents.

After every run, assuming that it will be longer than a few days before I run again, I drain my tank, blow the fuel out of the lines, and idle the engine on the box until it burn ooff the residual fuel (only takes about 20 sec.).

I then rinse my tank out with alcohol, put some ARO through the engine, and it's good until the next time I run, whether it's a few days, or a few weeks. Some folks may see this as overkill, but I do it just to make sure that my equipment stays in the best shape possible.

And I stop my engine by tapping the flywheel, or setting it on the starter box and pushing it down into the wheel (make sure the box power is off when you do this). You can tap the flywheel, or cover the exhaust...you'll find opinions on both sides of the subject. Bottom line....stop the engine however you feel most comfortable.

Run the car out of fuel before storage. The alcohol in the unburnt fuel is what causes moisture to build up in the engine and cause rust. There is absolutely no harm in running the fuel out of the engine, there is a ton of oil left over in it afterwards.

I have heard that plugging the pipe to stop a motor is bad for your front bearing. I do not know if it is true or not. I always stop mine with the flywheel and have never had a problem.

I run out all the fuel out of my engines. A few drops of after run oil. Make sure p/s is bdc.
I turn off my vehicle by pinching the fuel line. Whoever is telling you its bad for the engines is mistaken.

I don't even think about it. I either plug the pipe or stall the motor by turning the box off and pressing down on the wheel. I'll leave it if it runs out of fuel. Unless you're going to leave the motor more than a week or two, there's not much point in doing anything. The exception is making sure you're at bottom dead center when you motor is still breaking in. After break-in, no big deal. Let the engine dry out (pull plug, open throttle) and use some after-run oil if you're going to let it sit for an extended period of time to keep the methanol from corroding the internals.

I agree. Common guys, harden up!

Back on subject, I also empty the tank, idle engine on starter box until fuel is gone, couple of drops of ARO, and then BDC.
