Motor Oil Reviews

What is a Motor Oil?

Motor Oil1Depending on the age of your car, you may have a choice between synthetic and standard motor oil for your car. A lot of the newer cars are designed to use synthetic motor oil, but if you have an older vehicle, you may still be able to decide whether you would rather use standard or synthetic.

We’ll go over the different factors that come into play when it comes to making that decision so you will have all of the information you need to make the best choice for your particular vehicle.

Synthetic Vs Standard Oil

Regular oil, or standard oil as it is called, is made from crude oil through refining processes that will take out or separate the unwanted elements from the crude oil. After it has gone through this process, there will be a type of oil left that can be used for many different lubricating jobs.

Engineers started looking for alternatives to standard motor oil in the 1930s. These searches led the engineers to prepare esters, including polyesters, banana oil and diesters. The first to use synthetic oil was the aviation industry during WWII in the 40s.

It was not used in cars until the middle of the 1960s. At that time blends of synthetic oils and minerals were introduced and in 1974 Mobil 1 was introduced, changing things significantly. The components that synthetic oil is made from include chemically modified petroleum and other raw materials as well.

What Oil Viscosity Means

If you’ve ever seen a bottle of oil in the store, chances are you will see SAE or a combination of letters and numbers such as 5w-30 or something similar.  These letters and numbers are a viscosity grading that has been given based on the amount of heat, friction and pressure that the oil can maintain a solid state under. The first number indicates the vehicle from the starting position and the second number represents the vehicle at normal operating temperatures.

Using our example above oil with a weight of 5w-30 would have a viscosity or thickness of 5 upon starting, which means it will flow easier, and at standard operating temps, it would have a thickness level of 30.

The higher the viscosity number is the thicker the oil is.  In general, oil will thin as it heats up and thicken as the temperatures drop. It is not a good idea to mix thinner oil with a hot engine. This will cause more wear and tear on the engine.

On the flip side, a thickness level that is too low can be dangerous for the engine. If the oil is too thick during cold temperatures especially, it can make the engine harder to start and also take longer to get the parts lubricated properly.

Advantages

There are many benefits to using synthetic motor oil as opposed to standard motor oil.  These benefits have caused it to rise to the forefront in the automotive industry.  Synthetic oil has been shown to perform much better than standard oil in many ways.  There are some circumstances in which standard motor oil is a better choice and we’ll tell you what those are.

Some applications, such as some types of airplanes, use both. For the aircraft jet engines, synthetic oil has to be used, and aircraft piston engines can use either one safely and efficiently.

Motor Oil2Economic – When using synthetic motor oil, you will find that the oil needs to be changed less often that when using standard motor oil.  When using standard motor oil, the schedule for oil changes is typically every 3000 miles.  But synthetic oil is designed to last longer and it does, requiring oil changes only every 5000-7000 miles. This adds up to a savings in auto maintenance.

Automotive – Since the lubrication of the engine is better served with synthetic oil, it improves the gas mileage and maximizes horsepower as well so your vehicle runs longer, smoother and cooler.  The reason the gas mileage is better is because there is less friction inside the engine.

The increased horsepower will also help the vehicle use less gas as well.  Other great automotive benefits to using synthetic oil is there is less oil sludge issues, it has a resistance to oxidation and thermal breakdown, it has less thickness breakdown and overall just runs better.  You will definitely notice a difference in cold weather because a car will start easier that is using synthetic oil.

Environment – Neither of the oils is better than the other when it comes to the environment because both are obtained from petroleum based materials.   It does have an indirect impact on the environment when it comes to the improper disposal of oil after DIY-ers change their own oil.  Not everyone realizes that there is a specific way that old automobile oil should be disposed of and that is not in the sewers, trash or dumped out in nature somewhere.

To dispose of your old motor oil properly, take it to an oil change facility that will accept used motor oil, or to a household waste recycling facility.  Always be certain to call first to make sure they accept used motor oil.

If you have a recycling facility hear you, this is an excellent way to help the environment because they make use of the used motor oil by cleaning it and turning it into fuel oil.  It can be converted gallon for gallon. In other words, 1 gallon of used oil with provide one gallon of fuel oil. Used motor oil can come from cars, trucks, motorcycles, boats, tractors, and lawn mowers.

Disadvantages

Synthetic motor oil can cost 2 or 3 times more than standard motor oil. This can be a deterrent to people, but not a big one in light of the fact that there is more time between oil changes which will offset the cost increase. Synthetic oil can cause potential stress cracking of any of the plastic components that are made from polyoxymethylene or POM when it is alongside PAO.

Another potential issue can be gummy deposits on the seals of the combustion chamber due to the burned synthetic oil. This is a problem among vehicles that have rotary engines and is why they are not recommended for use in those types of vehicles.

How to Decide Which Oil to Use?

Even though synthetic motor oil tends to outweigh standard in many ways, it is not always the right choice for your vehicle. If your car has excessive miles on it, standard oil would be a better choice. In addition brand new engines need to be broken in properly before having synthetic oil used. A good break in period is to have at least one or two regular oil changes before switching to a synthetic.

Motor Oil3You may find that synthetic oil is used in high performance engines quite often due to the right engine tolerance, high compression and operating temperatures. The good thing to know is that unless the vehicle operation manual specifies one type of motor oil over the other, car owners can use both synthetic and standard oils without problems and the two kinds of oils can be mixed as well. As far as oil filters go, they will work equally well with either synthetic OR standard oil.

Conclusion

It will depend on the vehicle as to which motor oil is the better choice for your particular vehicle. If the car is new or if it has more than 120,000 miles, you will want to stick with standard motor oil. You can pretty much count on using synthetic for all other situations and vehicles since it helps the car start easier in cold weather, gives the engine better lubrication and provides better breakdown of the oil’s viscosity.

The top rated motor oils reviewed here are all synthetic and are all customer favorites due to their performance. They will all be excellent choices for your vehicle as long as they don’t fall into the two categories we have mentioned above.

With the information you have learned in this buyer’s guide and the reviews, you have the necessary knowledge to choose the best oil for your vehicle and actually know what is being out into your car. You can even request synthetic in the circumstances where you actually have a choice. Your vehicle will perform better and you will appreciate the longer lasting engine and less frequent oil changes to boot.
