What's Gasoline Octane?

Have you ever wondered why there are different grades of gasoline? All grades of gasoline have what’s called an octane rating. So what is it and, more importantly, what should you use in your vehicles?

What It Tells You

First of all, the engine in your vehicle burns fuel by compression – in other words, your engine is an internal combustion engine or burns fuel internally. The engine allows a mixture of air and fuel into the combustion area and a piston then compresses this mixture. Your spark plug then ignites this mixture causing an internally explosion that produces the power to run your engine.

Therefore, the octane rating tells you how much the gasoline can be compressed before it ignites spontaneously. Should gasoline ever ignite by compression rather than by the spark plug, then it would cause the engine to knock, possibly damaging your engine (think of it as taking a hammer striking the top part of your piston) – obviously this is not something that’s desirable.

For Example

Take regular gasoline with an 87 octane rating for example. This grade of gasoline would require less compression than gasoline with a 93 octane rating. Simply said, the higher the octane, the more compression it takes before spontaneous combustion occurs. Another way to look at it is that, the higher the octane, the slower the fuel burns, whereas a lower octane rated gasoline burns faster.

Why It Matters

If you use a lower grade of gasoline than what your vehicle manufacturer recommends, then you run the risk of engine damage caused by pinging or pre-detonation. And if you’re using a higher grade of gasoline in an engine that wasn’t originally designed to handle a higher grade, you can actually reduce engine performance and gas mileage. How so? Since the higher grade of gasoline burns slower and you’re using it in an engine that was designed to burn a faster burning fuel, you therefore don’t burn all the fuel. If you don’t burn all the fuel, then all the air that is in the mixture isn’t burned either. Your vehicle computer sees more air in your exhaust system and then compensates by adding more fuel to this perceived lean running condition (more air).

In short, you have more raw fuel being pushed through your exhaust system, causing your catalytic converter(s) to over work and possibly lead to premature failure, not to mention the pollutants released into the air. Unless you’ve had modifications performed to your engine (and computer reprogrammed) to run properly on a higher grade of gasoline, you won’t improve the performance of your vehicle just be buying a better grade of gasoline.

What To Buy

So which grade of gas should you buy? Use the grade that your vehicle manufacturer recommends unless you’ve had your engine modified and your computer reprogrammed to burn a higher grade of gasoline.

Brake Caliper Servicing? What's That?

May 31, 2018 Category: , Brakes

If youre not a hard-core car enthusiast, you may not understand all of the maintenance that needs to happen to keep your vehicle running at its best. One important process that you might not realize your vehicle needs is brake caliper servicing. You may be wondering what brake calipers are! Brake calipers house the brake pads and, using brackets, pistons and caliper slide pins, help push the pads into the brake rotors when you apply the brakes. Over time, the slide pins lose their lubrication and dont slide the calipers so well. This lack of lubrication causes a few things to happen. First, because the brakes dont contact the rotor properly, your brake pads can wear unevenly. Second, the slide pins may stick, causing the brake pad to continually contact the rotor, resulting in a buildup of heat, which wears your brake pads down faster. Third, your brakes stopping power may be weak due to the brake pads not hitting the full surface of the brake rotor. All this means you arent getting the

Squeaks and Noises

Now that the weather is (finally!) warming up, you are sure to be driving with the windows down, enjoying the warm breeze. Also coming through the window may be squeaks noises you hadnt heard with the windows rolled up. A loose or worn serpentine belt will cause a squealing noise coming from under the hood. A slipping belt can be heard immediately after starting the car when the belt starts to move. Have your automotive professional check if the belt is loose or needs to be replaced altogether. Squeaking noises may be a sign that your brakes need to be inspected, or perhaps your shocks struts took a beating this past winter. Do you hear thenoisewhen you turn a corner? Thisnoiseusually comes from yourcarssuspension and often is caused by normal wear or from hitting potholes or other road debris. Worn out bearingsmake noise as well, as they are a buffer between the axle and the wheel. The friction from the worn-out bearings is what can cause the humming noise. Under-inflated tires

Preserving the Life of Your Fuel Pump

Two Tips for Helping Your Fuel Pump Last Longer Fuel pumps can be an expensive and unwanted hassle to replace. You can improve fuel pump longevity in your vehicle by using these simple tips. Save yourself time, money and stress by incorporating the following into your car-care regimen. 1. Avoid Contamination Fuel tank contamination can destroy your fuel pump. Contamination can occur from the fuel itself or simply from an older fuel tank. Buying your fuel from a reputable pumping station can reduce the risk of poor-quality fuels contaminating your fuel pump. When the fuel is clean, the risk is considerably less. If you are dealing with an older vehicle and therefore an older fuel tank, the build-up of rust from corrosion that can occur over many years may be contaminating your fuel from inside your vehicle. The solution here is to have your tank cleaned thoroughly. In some cases, depending on the level of corrosion, it may even need to be replaced. 2. Dont Go Below a Quarter Tank Youre
