YES.
Fuel will last only about a month (even that's pushing it) add a bottle of fuel stabilizer (available at your local hardware store) and the fuel will be good for "almost ever"
yes
Nothing except possibly a fuel stabilizer if you're going to store the vehicle. You may also want to add a good fuel injector cleaner such as Seafoam or Techron once a year.
Shock first, then check your stabilizer. Add stabilizer as needed.
yes, if fuel is going to sit for extended periods you need to add fuel stabilizer to it
Add fuel stabilizer to your gas tank to allow for easy starting after storage.
Diesel fuel itself will burn but you really can't call it flammable. When you add gasoline to it, the flammability greatly increases with the amount of gasoline you add.
Every year you should change the oil, grease all the joints, and add fuel stabilizer before you store it for the winter.
Add chlorine and stabilizer.
Have the coolant tested to be sure it will protect from freezing to at least -34 degrees F. Add a fuel stabilizer to the fuel tank and fill the tank with fuel. Run the engine to get the stabilizer throughout the system. Once parked remove the battery and store the battery in a safe place to keep from freezing. Perform a trickle charge on the battery once a month.
add 1.5 octane to your gas. Every 10 points is one octane when added to fuel if u follow instructions.
It is hard to give a definite answer because it depends on how you store it. Assuming the gas was fresh when you bought it, you store it in a cool place, in a sealed container with the container full, and you use no fuel stabilizer, it will stay usable for about 2 months. If you add a fuel stabilizer it will stay usable for about 12 months. Do not use any fuel stored for over 12 months as it will contain some sludge which can clog injectors and carburetors.
