Is synthetic engine oil more efficient than conventional engine oil in terms of fuel efficiency?

We are not always as knowledgeable as we believe when it comes to better understanding our vehicles.

According to a recent poll, 81% of drivers have no idea how many miles their car should travel between oil changes.

Could something as simple as the type of lubricant you use when topping up your engine oil be a step in the right direction for petrol-powered vehicle owners at a time when electric vehicles are leading the way in lowering fuel costs?

There are several ways to improve your fuel economy, such as driving more smoothly, shifting gears more efficiently and never lending your car to children, but does the type of engine oil you use during a car service in Reading really make a difference?

How many miles should you drive before getting your oil changed?

Oil should be changed every 3,000–5,000 miles as a general rule, but some vehicles and oil types can go up to 10,000 miles between changes.

What is the difference between synthetic and conventional engine oil?

Synthetic engine oil :

Synthetic engine oil is a manufactured product. Before being sold, these oils will be refined, distilled, and purified. They are disassembled and rebuilt before being filled with a variety of additives, each of which is designed to improve engine performance.

Manufacturers design the oils to reduce engine wear and sludge build-up at higher temperatures. They remove many of the oil's original impurities and tailor each addition to the needs of the engine. That explains why there are so many options.

Conventional engine oil :

Conventional engine oil is a naturally occurring product. It all began with the extraction of crude oil from the ground.

What components of synthetic oils make them more efficient?

Because synthetic oil is designed to include performance-enhancing products, those designed to reduce friction play a significant role in lowering your miles per gallon (MPG).

Friction-reducing additives :

Manufacturers have devised techniques for incorporating some very clever components into their oils. Molybdenum disulphide (MoS2) is one such additive that has been shown to reduce friction by up to 66%. You can expect to improve your fuel economy by 3 to 15% if you use synthetic oil with a 'moly' additive.

Thinner oils are more prone to evaporation.

Engineers create 0W ratings (the lowest viscosity) to reduce the workload on your engine's components, but it is much more likely to evaporate at higher temperatures. It would be unable to meet the standards set by industry regulators. It is nearly impossible to create the perfect oil. As a result, we must make the best decision possible for each of our individual vehicles.

What is oil viscosity, and what do the various grades mean?

The grade of oil you use is determined by the viscosity of the oil you use to top off your car's oil. The grade governs the flow of oil in both cold and typical high operating temperatures.

The following are 2 main questions that everyone asks when in comes to engine oil:

Why isn't it a good idea for everyone to use the thinnest oil they can find? - 

The density of the oil determines how much load it can carry and how much of the friction reduction it can perform. The oil will not be able to do its job if it is too thin. If it's too thick, your engine will have to work harder than it needs to.

What exactly do the terms '10W-30' and its many variations mean? 

- The first part of the viscosity grade, which is preceded by a W, denotes winter viscosity. This depicts the level of flow in your engine, starting in cold winter temperatures. The flow at normal operating temperatures (typically 100°C) is defined by the second component (the numbers following the hyphen).

A 0W-20 oil is thin and free-running, whereas a 15W-40 oil is heavy and thick

Lowering your oil's viscosity will increase your MPG, but by how much?

The oil's viscosity varies. The manufacturer of your vehicle will have advised you on which one is best suited to your vehicle. When you use synthetic oil instead of conventional oil, the efficiency difference can be significant enough to lower your miles per gallon (MPG).

What is the reasoning behind the vehicle manufacturer's suggestion or recommendation of a specific oil grade?

When it comes to engine oil, the recommended grade for your vehicle will take into account the vehicle's typical use, loads, and engine size. The manufacturer will have determined in the service manual the best option for you to get the most out of your engine's performance.

Depending on how the seasons behave where you live, you may choose to make accommodations for the level of heat.

Find an oil that will allow you to get the most out of your engine while not putting its health at risk.

With this new information, you'll be more likely to think about the type of oil you use the next time you perform an engine oil check. What you should not do, however, is choose an oil grade that will not provide the necessary level of protection for your engine in order to improve fuel economy. Think outside the box the next time you have a car service in Reading and replace engine oil. It would be nice to save a few pounds on fuel, but not if you have to replace your engine before it reaches the end of its expected lifespan.

Not only does the type of oil you use have an impact on your fuel economy, but a clogged air filter will also reduce your miles per gallon (MPG).

There are numerous components and consumables that affect your vehicle's engine performance. Did you know your air filter can help you save money on fuel? An overworked air filter, full of dirt and dust, clogged and dirty, obstructs proper air-to-fuel passage. This has the potential to have a significant impact on your fuel economy. This is also why a wide range of high-quality air filters are available.
