Difference Between Octane Grades


When you step back to compare grades of gasoline, you will see why some fuels are cheaper than others and how certain grades affect your vehicle. Although all types of gasoline are sourced from oil, the specific treatment and chemicals added to the oil is what determines particular purpose and grade. Using the proper fuel grade in your automobile helps to ensure its efficiency and protects the motor from excessive friction and overheating. The following information will help you understand the differences between the available grades of fuel.

The history of gasoline

Gas was once marketed in tiny bottles as a head lice remedy. Gasoline began to be used for fueling cars in the 1920s and it was leaded to help boost the efficiency of car motors. Fuel grades were also first developed during this period, beginning with two different grades: regular and plus. These gasoline grades were applied based on the amount of octane a fuel held.

Identifying fuel grades

Regular, plus, and premium fuel grades are all distinguished by how much octane they contain. Octane amounts indicate how volatile a particular grade of gasoline is. Regular gas carries an octane level rating between 85 and 88, with an average rating of 87. Plus grade gas carries an 88 to 90 octane level rating, with an 89 average. Premium gas comes with a 90 plus octane rating that averages out to about 92.

How different fuel grades burn

Fuels of different grades will not burn the same way. The less octane a fuel contains, the easier it burns. For machines and vehicles controlled by powertrains, the motors are created to consume the ideal amount of fuel at all times. The specific grade of fuel does not have much impact on a car’s overall performance in this case. Although all grades of gasoline produce similar levels of heat power, their rates of combustion can vary.

Benefits of different grades

The grade of a fuel lets you know how readily it will combust inside of your engine. Fuels with lower levels of octane usually burn faster and stronger when they are pressurized, which produces a ticking or knocking noise in your motor. Car motors that run on regular gas are designed to apply the ideal amount of pressure to prevent internal knocking sounds.

SUVs often run best on plus to premium fuels, as their motors are intended to produce more fuel compression for enhanced drivability. However, it is always best to check with the manufacturer or manual about the correct grade of fuel. There is no extra advantage to using plus or premium grades of gasoline if your automobile is designed to use a regular fuel grade.

Summer Tires vs All Season Tires


When debating between all season tires vs summer tires, the differences between the two types can be easily misunderstood. Depending on your vehicle, driving conditions, and personal preferences, one may be a better option than the other. When choosing between summer and all season tires, it helps to understand the benefits and limitations of each.


An all-season tire offers a balance of capabilities, providing acceptable performance in wet and dry conditions, as well as traction in snow.

Built for the average driver, all-season tires have moderate tread depths and rubber compounds that are engineered to provide longer tread life than summer tires, which have shallower tread depths. All-season tires are offered in many types/models, sizes, load capacities, and speed ratings for use on a wide variety of vehicles from economy cars to sedans to mini-vans to pickup trucks. They tend to provide ride comfort, handling, and other performance attributes suitable for most drivers.

All-season tires perform well in warm weather, but they may offer less grip than summer tires, sacrificing some steering, braking, and cornering capabilities. This trade off is necessary for all-season tires to be able to provide acceptable performance in light winter conditions and provide longer tread life.

All-season tires are capable of providing traction in winter, but are not the best tire to use in extreme winter driving conditions. Drivers who encounter extreme winter weather may want to consider switching to snow tires in the winter.

Because all-season tires offer a blend of summer and winter performance, they are often a good option for drivers in moderate climates and driving conditions.


Summer tires are ideal for high performance vehicles, and are built for speed and agility. They offer increased responsiveness, cornering, and braking capabilities. This is typically attributed to specialized tread patterns and rubber compounds that allow for improved precision on the road. The tread patterns of summer tires have less grooving and put more rubber in contact with the road. They are design­ed to provide maximum road-holding grip. The tread compounds of summer tires are designed to remain more flexible, allowing for better traction and grip. Summer tires may have shallower tread depths that allow for more stability when pushed closer to their limits.

Dimensional characteristics (such as the tire’s width, aspect ratio, and rim diameter), speed capability, and other design features make summer tires more suitable and capable for increased performance in wet and dry conditions on high-performance, sports-oriented vehicles. Surprising to some, summer tires provide better performance in wet driving conditions, thanks to unique tread patterns that help evacuate water and resist hydroplaning.

When it comes to winter driving, all-season tires may be more suitable than summer tires, given their blend of summer and winter performance capabilities, but we recommend considering making the switch to winter tiresto get optimal traction and performance in extreme winter conditions.

Should I Worry About How Hot My Engine Is Running?


You should be very concerned, because an overheated engine can be far more than an inconvenience. In extreme cases, driving an overheated engine even a short distance can destroy the cylinder head, engine block or internal parts.

Fortunately, most modern vehicles have a gauge that displays a constant temperature reading of the coolant circulating inside the engine, giving the driver an early warning about the cooling system.

The normal operating temperature for most engines is in a range of 195 to 220 degrees Fahrenheit, though most dashboard temperature gauges don’t show an exact temperature. Instead, there are typically markings for cold and hot on the edges of the gauge and a normal range in the middle. In most vehicles, the temperature needle will be at or near the center when the engine is at normal operating temperature, which usually takes at least a minute or two to reach after starting a cold engine.

Why Are My Brakes Squealing?


If you’re lucky, the squealing (or squeaking) noise that your brakes make when you first drive your car in the morning, particularly after rain or snow, is just surface rust being scraped off the rotors by the pads the first few times you apply the brake pedal, or the result of moisture and dirt that collects on the rotors, including from condensation caused by high humidity. If it goes away after a few brake applications, no worries.

If the noise persists most times or every time you apply the brakes or stays on continuously while you’re driving, the cause is more serious — and the fix will be more expensive.

A continuous high-pitched squeal while you’re driving is usually the sound of a built-in wear indicator telling you that it’s time for new pads. As the pads wear down and get thinner, a small metal tab contacts the rotor like a needle on a vinyl record to warn you it’s time for new pads. (Some wear indicators may work differently and engage only when you apply the brakes.)

Signs You May Need a Tune-Up


If your engine misfires, hesitates, stalls, gets poor mileage, is hard to start or has failed an emissions test, it clearly needs something, though a tune-up in the traditional sense might not be the cure.

If you tell a repair shop you need a tune-up, the mechanic should ask why you feel you need one before recommending any service. Just like a doctor should ask what symptoms you’re experiencing, a mechanic should seek to diagnose the problem. And just as a doctor may recommend some tests, a mechanic may do the same.

You can speed the process by being ready to describe what happens and when (such as whether your car hesitates when the engine is cold or when passing at highway speeds), any sounds you hear and what you feel when your car’s “illness” shows up.

One caution about lower fuel economy: You should expect it to go down at least a little during the cold months, and maybe a lot. Colder temperatures make your engine and charging system work harder. In addition, winter gasoline blends have slightly less energy content than summer blends, so they don’t deliver as many miles per gallon. A tune-up won’t make Old Man Winter, or his effects, go away.
