How long have you been driving? Most people say since they were sixteen years old or even younger. Driving for that long will obviously improve anyone’s driving, but there will always be room for improvement. Whether that’s getting rid of distractions or simply changing how you drive, here are some tips that are sure to better your driving.

oil change

At Glenn's Auto & Truck Repair in Petaluma, we understand all too well the importance of changing your oil regularly. Three to five thousand miles sounds like a lot, but it doesn’t really take that long to rack them up. The busier you are, the more you probably drive, and the more likely you are to forget it’s time to change your oil. Here are some reasons to pay attention to your oil changes, and help you better understand why oil changes are so important.

dirty air filter vs clean filter

Your vehicle's engine needs clean air to burn the fuel – and it needs a lot of clean air. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Glenn's Auto & Truck Repair in Petaluma, we ensure you get the best air quality in your vehicle and explain the process of where this dirty air is going to our area drivers. 

fleet of diesel vehicles

If you own or operate a fleet or commercial truck, you’re probably pretty familiar with diesel vehicles. But why are diesel engines predominantly used in commercial vehicles, and where did they start?

At some point, while waiting for your tank to fill up, you’ve probably wondered what the difference is between the choices of gasoline at the pump. Typically, you see three buttons, with a number between 85 and 98, in ascending order and ascending prices. These numbers are octane ratings, which you probably know; but what is an octane rating, really?

fuel gauge on a vehicle

Your gas mileage mostly depends on what kind of car you drive; engine displacement and vehicle weight are the largest determining factors on gas mileage, and there’s not much you can do to change either of those. That doesn’t mean attempting to improve your fuel economy is a completely hopeless endeavor, however. With these tips from Glenn's Auto & Truck Repair in Petaluma, CA, you might be surprised how much your fuel mileage can be improved.

codes on a dashboard
