Tips for using synthetic oils
How to Choose the Best Engine Oil
There are many brands of engine oils in the market. This makes it hard for a newbie to settle for the best deal. For a start, the best brand will definitely have many customer reviews than an emerging brand. When choosing engine oil, you should consider its ability to run on both gasoline and diesel engines.
Oil that supports both types of engines is better because you will not buy two types of oils which in return helps you save money.
It’s also advisable to settle for a brand that has been approved by major automakers. Such a brand will offer an excellent performance. In fact, when a brand bears certification from major manufacturers such as Ford and BMW is the best because such companies are very good in testing consumer products.
The good thing is that some brands exceed the requirements that are specified by these manufacturers. Besides that, the oil should retain its liquid state when exposed to high temperatures. Ordinary oils tend to breakdown when subjected to a lot of heat. Such an oil is not ideal for an engine that’s run for many hours.
What to Look For in Good Engine Oil
When buying engine oil, you should settle for a brand that works well regardless of the changes in weather. There are oils that freeze during winter because they can’t withstand low temperatures. When this happens, the engine of the car or any other equipment takes long to start due to the fact that the oil flows slowly.
There are also others that evaporate when you drive in extremely hot climate. It is also important to consider the viscosity of the oil. This is normally abbreviated SAE 0W. The lower the number before W, the better.
Most oils have a viscosity of 5W. Such oil can remain thick despite being exposed to harsh weather conditions. This thickness helps in keeping friction at bay because the moving parts can’t come into contact when the engine is turned on.
You don’t have to settle for an expensive brand because competition among manufacturers has led to the emergence of low budget oils. Good oil comes packaged in a plastic corrosion.
This kind of packaging gives you the convenience of carrying the container to wherever you are going. Besides that, buying oil in 5 quart is economical than settling for 1 quart. High quart means you are getting more oil.
Do you want to switch to full synthetic oil?
If yes, then you should check your manufacturer’s manual to see its recommendations. If you use an oil that is not compatible with your car model, it can void your warranty. Also, ensure that the synthetic oil you intend to use is compatible with other types of oils as you just need to top up with the new oil. If it is not compatible, you will have to drain the entire oil.
How do you check if the oil in your engine is adequate or not?
After changing or filling oil, let the vehicle run for some minutes. After that park in a level space. Allow the car to cool down and then remove the dipstick and wipe it. Put the dipstick back again and then remove it to check the oil level.
- If you are a DIY fanatic and want to change the oil yourself, ensure you do not overfill the engine. Overfilling the engine may cause the engine to overheat and damage the engine
- Synthetic oils absorb heat in the engine as they act as a coolant. However some engines such as racing car engines generate a lot of heat. Therefore, you can consider adding coolant to cool them off.
- Carefully read the label of the synthetic oil you intend to buy. Different synthetic oils come with various additives and applications as you need to ensure that oil meets the needs of your engine. For instance, using an oil meant for vehicles on a motorbike may damage it.
- Synthetic oils are slippery. If you want to use them in high mileage vehicles, ensure they have properties to rejuvenate the seals. This will prevent leakages.
