There's no question in our minds!
Without question, the most expensive thing that's happen to people and cars is self service gas. Sure it's quick, but it is very costly. Why? Because most people do not check their under hood fluid levels or tires anymore. They simply fill up with gas and keep on going. We see people destroying their engines and transmissions because of this problem. Just because you drive a newer car, it doesn't mean you can't get low on oils. Don't make a huge costly mistake. If you go to the self service gasoline pump, have your mechanic teach you how to check your under hood fluid levels and tire pressure.
