Hi, I'm Bob Holcomb from Apex Automotive in Great Barrington, Massachusetts. We're going to talk about the gasoline in your car and how to tell if your gasoline is bad. One of the ways to tell if your gasoline is bad is the odor. Gasoline has a distinct odor. The hydrocarbons that evaporate off the top of the gasoline smell like gasoline. If it smells in error or has a foul stale smell to it I guess it just comes from experience, if you have good gasoline by smell or not. Another way to tell is by looking at it. It should be clear. There should be nothing in it. There should be no particles and no droplets, especially at the bottom. Most of your particles will settle quickly to the bottom as the gasoline, the molecules are very thin. Your car will tell you if you have bad gasoline simply by putting on your check engine light. If your gasoline is not burning correctly, the modern car from 1996 and newer are smart enough to tell that the gasoline is not burning correctly and it will start to try to add more and more gasoline because it's not combusting. As it adds more and more gasoline the car will run poor and your check engine light will come on. The certain codes that your car gives will tell us if we have bad gasoline. One of the codes could be P0171 but that type of diagnosis is better left to the professionals. It's always a good idea to get your gasoline from the same gas station, each and every day. That way we have a constant or a baseline if you will that if our car is running poorly and you're getting the gas from the same station day after day, the gas is probably not the problem. And those are a few tips on how to tell if your car may have bad gas. I'm Bob Holcomb from Apex Automotive in Great Barrington, Massachusetts.
