So, I don’t know about you but I have this really bad habit of topping off my gas tank, trying to get the dollar amount to be a flat number (like $20 or something ending with a .50 or a whole dollar number). I say bad habit because it’s actually not the best for your vehicle to top off the tank. Why, you might ask? READ ON. It surprised me too.

First of all, overfilling your gas tank (which is basically what topping off is) can overwhelm the evaporative system in your vehicle, which can either break something or cause a leak in an inconvenient place due to built up pressure. Pressure builds as heat increases, so when your vehicle heats up from being driven right after you’ve topped off that tank… well. Recipe for disaster!!!

The second thing is that it’s honestly just a waste of money. Most modern fuel pumps come with a handy system where if the nozzle detects that there’s too much fuel in the tank, the gas you’re trying to pump into your vehicle is just going straight back up the hose and into the station tank. So, you’re getting charged, but you’re not actually getting the gas you’re paying for.

It’s a hard habit to break, and I am still working on it, but we should work on it together. Share this with your friends and family, and celebrate your savings!
