Everyone from car 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, we keep things clear and simple. The more you know about your car, the better equipped you are to keep it maintained, and we know a thing or two about cars. We have compiled a short list of common myths for you, most of which you’ve heard, but maybe never second guessed.

Buying a used car can be a risky endeavor, but also a rewarding one. Buying used, even if the car is close to new, will save you a lot of money compared to the price of a new car off the lot. However, there are some inherent risks that come with purchasing a used car; here is how to best avoid trouble.

Coolant is vital to your engine. Without the right type, amount, and proper circulation of coolant, your engine won’t last long. How do you know when it’s time to check it or replace it? Harold's Used Auto Parts Inc in Philadelphia has the answers.

Tire rotations are a part of vehicle maintenance. The purpose of rotating your tires is to make them last as long as possible, prevent your suspension from wearing out prematurely, and keep the drivability of your car in the best possible condition. So when should you get a tire rotation?

If you drive a vehicle with more than a few miles on it, there’s a good chance you’ve noticed an occasional drip underneath it that leaves spots wherever you park. Identifying what is leaking from your car will help you determine whether or not it’s a cause for concern, and what to do about it.

There are seven liquids a car can possibly drip: oil, gas, brake fluid, transmission fluid, gear oil, water, and coolant. How do you tell the difference? This article aims to help you know how.

Your Vehicle Identification Number, or VIN, is essentially your car’s fingerprint. In its entirety, it is specific only to your car. Each car has its own unique VIN number, and can be decoded to provide manufacturing and identification information on any vehicle on the road. Date of manufacture, manufacturer, vehicle type, where it was made, and options such as engine and transmission type, whether a car is a two or four door, and a multitude of other specifications can be gleaned from a VIN number. Essentially, a VIN number will tell you exactly what a car is and where it came from, without even having to see the car.

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?

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 flood waters 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.
