Keeping a full tank keeps your car healthy. Experts that are familiar with the common fuel injection system will tell you that running out of fuel can cause serious fuel line problems - and that running low can be detrimental, too. Running out of fuel in a fuel injected car can allow small particles of dirt and rust that are concentrated at the bottom of the gas tank get sucked by the fuel pump. When this happens, some of that dirt can work its way past the fuel filter, into the injectors, causing major problems.

thats half the truth what would have happened to the filter/strainer on the pump itself then the filter on the line

so the solution is not filling up the tank but get the tank cleaned, the pump filter/strainer changed and the line filter changed


the tricky part is for diesel car if you run out of fuel and refill you need to prime otherwise the wont start and there would be air in the fuel lines

Carrying full tank does not keep your car healthy in any way. Just make sure you do not get to reserve. I top up at 1/4.

For me, always carrying full thank reduces fuel economy because it is extra load. I drive as light as possible. If travelling, I go full tank though.

Very nice and useful advice. Is there an expression... Miser pays twice? It's just about this main problem of the car owners.

u r right but not just because of weight. Trying to fill the tank comes with the tendency of attendants to overfill. This damages the charcoal canister over time and results in evaporation emission codes.

Still following and learning. Some of us only drive we don't know many things about our cars.
