The steering and suspension systems are key safety-related systems that largely determine your car’s ride and handling. Have these systems checked regularly, at least once a year, and usually with a wheel alignment.

On average, today’s vehicles get better gas mileage than ever. There are still ways to get the most out of the fuel that you put into your tank. Here are the factors that affect gas mileage, and what you can do to maximize yours, from Harold's Used Auto Parts Inc in Philadelphia, PA.

Unless you are confident in your abilities as an automotive mechanic, there is really only one rule when purchasing a flood-damaged vehicle: don’t do it. Unfortunately, sometimes sellers aren’t particularly straight-forward with their used cars. Many will try to hide the fact that it’s been damaged by floodwaters at all or try to convince potential buyers that the car is in fact fine. “It has gone months with no issues” or “technically it is flood-damaged but” are two red flags, and while it isn’t impossible for a flood car to be fine, it’s altogether a good idea to stay away.

Oil being poured into a vehicle

Everyone from mechanics, to your uncle that works on cars, has at some point given you advice concerning engine oil. The fact of the matter is that while we are familiar with words like “synthetic” and “oil weight,” many people don’t know exactly what the terminology means, or why common knowledge about oil exists in the form that it does. At Harold's Used Auto Parts Inc in Philadelphia, PA, we keep things clear and simple. The more you know about your vehicle, the better equipped you are to keep it maintained, and we know a thing or two about vehicles. We have compiled a short list of common myths for you, most of which you’ve heard, but maybe never second guessed.
