Do you have to use the Manufacturers Engine Oil?

In Engine Oil by Magnus Sellén2 Comments

manufacturers engine oilThe first thing you need to find out after purchasing a new car is what type of oil the manufacturer recommends.

Oil is graded based on its viscosity which in loose terms is its thickness. Oil is vital for the smooth operation of the engine. It circulates through the engine from the oil pump where it is put under pressure.

The oil will circulate through the engine and bearings while cooling and lubricating it. It will then go to the oil pan where it is stored and cools. During this process, the oil will be contaminated by the engine byproducts and dirt. A sludge will often form at the bottom of the oil pan. Oil is amber in color but after continued usage, it turns to black color.

The car performs at its optimum level when certain oils are used. You can either use synthetic or mineral based engine oils. Each has its own set of pros and cons. Since the manufacturers are the one who designed the engine it is prudent to follow their recommendations.

Wrong engine oil will contaminate your engine and reduce its efficiency. If you have a high-performance car engine you can use premium engine oil.

How oil viscosity affects performance

Engine moving parts tend to have space for oil and this prevents them from coming into contact with each other. If this happens friction and heat are produced and the parts will wear out faster.

Viscosity is a term used to describe the thinness of oil. Cars metal moving parts interact with each other is measured by tolerance. If parts have a high tolerance it means there are very close to each other. Such kind of engines is found in high-performance cars. In other cars you have less tolerance meaning the gap is larger and you have leeway on the type of engine oil to use.

Each engine oil type has an indication of its viscosity. If you buy the wrong type then the metal parts will grind against each other producing friction and subsequent tear. There is a universal industry standard for measuring oil viscosity. You should consult your manufacturer’s manual for the right type of engine oil.

Do you have to use the manufacturer’s engine oil?

It’s always recommended to use the manufacturer’s engine oil if the car is new and you want to keep the warranty of the car. However, if you are purchasing aftermarket engine oil, make sure that the engine oil is following the manufacturer’s specifications for the engine oil.

A lot of car manufacturers use tracer in their engine oil. With this tracer, the manufacturer can check if it’s their recommended engine oil in your engine in case of an engine failure. It’s of course, not very common that they are checking this, but in a new car with expensive repair costs of your engine, they could.

In this situation, if you are using another engine oil, they may reject the payment for a new engine. If you have an older car without a warranty, you can purchase another engine oil manufacturer, but it’s always best to make sure that it’s compatible with the manufacturer’s specifications of the engine oil.


oil filterEngine oils differ with the type of additives added. Cars are designed to operate in certain climatic conditions. There is a type of oil that is not suitable for use in extreme cold or hot weather conditions. Dirt can cause the seals from functioning well. In this regards, engine oil has detergents added to it to prevent the buildup of dirt deposits.

Additives help the engine oil to perform under different climatic conditions while detergents will prevent the buildup of rust in the metal components. In some instances, they will react with the dirt components and dissolve them.

The last components of engine oil are the dispersants. The oil filter is vital for the removal of contaminants from the oil. If the sludge settles at the bottom it can be hard to remove. Dispersants will react with contaminants and suspend the mixture so that the oil filter can carefully remove it.

Each of the engine oil types will specify whether they contain any of the three. However, some are so highly marketed on the effectiveness only to disappoint when added to the car.


Car owners are also at a crossroads at how engine placement affects performance. For most cars, the engine is at the front and you have a storage trunk at the back. The configuration of the car is dependent on how the wheels are placed and whether the car is a front or rear wheel drive.

The location of the engine will affect performance hence the type of oil you use will matter. A lot of sports cars have a rear mounted engine. This kind of engine placement leads to more braking power and acceleration. Most of the car weight is at the rear and the car may need some force to push the car weight forward. But, once it does acceleration becomes easier.

Replacement Interval

For most people they have lived under the myth that you need an oil change every 3,000 miles. But, engines are becoming more efficient and can actually do more than 8,000 miles without an oil change. In fact most car experts do not advise the constant oil changes by motorists. The reason the change oil after 3,000 miles gained traction is an attempt by manufacturers to market their products.

For most of the car owners they rarely or never read their manufacturers manual. They will instead follow the sticker laid out during the last oil change. Engines have become more efficient and this means the driver has less influence on engine oil consumption.

Long-life engine oil

Most of the auto makers have recently suggested having an oil change after doing 7,500 or 10,000 miles. In some models like the Jaguar an oil change can be done after 15,000 miles. However, you can do it sooner should you notice leaks.

Oil leaks can cause your car’s metal components to grind against each other causing a lot of friction. This friction is not good as it produces a lot heat and wears out metal components. Synthetic motor oils have pushed the mark for which you need an oil change. With some suggesting an oil change after every 10,000 mile mark.


It is vital that you follow the manufacturer’s manual before the next oil change. Since it’s the manufacturer who made the engine they understand the viscosity of oil and which type is best for lubrication. Modern engine oils are created to be more efficient and long-lasting. Instead of the customary 3,000 miles oil change, some of the engine oil is still usable even after the car has traveled for 10,000 miles.

Car owners should check the car’s manual for oil change instead of the usual service sticker. Modern synthetic engine oils have tighter tolerance hence reducing the chance of metal parts coming into contact with each other. They also work well to protect the engine from wear and heat. Most car owners have a preference for them.

Hello I'm Magnus, the owner and the writer of this website. I have been working with cars since I was 16 and I'm specialized with in-depth Automotive diagnostics. Also been driving drifting for the last 6 years. I'm here to give you answers to all your automotive questions and I hope that you enjoy our content.

  1. Hello Magnus,my question is as follows,I drive a 1984 Honda (Ballade) South Africa or better known as a Civic in the UK it is a 12 valve 1500 automatic. During a trip we encountered an obstruction on the tarred road an had to go off the road on to the uneven terrain,I suspect that the drive shaft pulled out but momentarily but is now back in the correct position. Some of the oil has leaked out. I will replace the oil seal and then refill the differential with the oil specified in the manual SAE30, 10W-30 10W-40 or 20W-40 I am not sure if these oil’s are in fact engine lubricating oil or is it a special transmission oil.

  2. Good day I want to produce my own engine oil what do I need to produce my own engine oil
