Changing Fuel Level

IKR... but that resets the whole car. If I want to keep my engine heat or damage level, it's not the way, lol

i like to get my odometer as high as possible, XD

 

Actually, if you use the code Diamondback posted, you can set the fuel on the go. Open the console with the ` or tilde key and type this:
energyStorage.getStorage('mainTank'):setRemainingVolume(60)
Just change the 60 to whatever the fuel tank's limit is. One thing I found was if I was completely out of fuel and the engine died because of it, even with a full tank it wouldn't restart properly.
