Frequently asked question


Is 5W-20 good oil?

5W-20 oils are good at staying fluid at low temperatures. The density of this oil is maintained over a fairly long time period, shifted to low temperatures. These oils also work well at high temperatures but it may not withstand extreme loads. 5W-20 oils are definitely good for riding in winters with a moderate climate, although, they’re designed as all-season oils.

Is 5W-20 oil full synthetic?

5W-20 oil is typically fully synthetic because it has better fluidity at sub-zero temperatures. However, semi-synthetic oils, e.g. Motorcraft SAE 5W-20, are also pretty common. The oil has its advantages and is designed specifically for Ford cars with powerful engines.

Special attention should be paid to technologically advanced oils. They are also fully synthetic but are more effective inside car engines, minimizing their wear, reducing friction, and cleaning them from the inside. Their price can be slightly higher than that of conventional synthetic oils but the effect is felt immediately.

Is it OK to use 5W-30 oil instead of 5W-20?

If your car specifications require the use of 5W-20 only, you should not use 5W-30. Generally, switching to 5W-30 should not cause irreparable damage significantly affect your car. Such engine oil has a denser structure and, thus, loads the engine more. As a result, the engine performance will be lower and fuel consumption will slightly increase. In all other respects, these oils are quite similar.

How many miles is 5W-20 oil good for?

The oil change period of 5W-20 depends primarily on the oil, car, engine condition, and regular loads. In general, it is recommended to change synthetic oils after about 10,000 miles. If you consider advanced synthetic oils by Pennzoil or Mobil 1, in some cases, you can change them every 20,000 miles. Of course, this is the maximum period, so it’s always a good idea to keep an eye on the oil’s condition in the engine, its volume, and change it in time. It is also recommended to use oils of the same brand, if possible.

How often should I change 5W-20?

Most engine oils, including 5W-20, should be changed every 7500 miles. This is especially true for older cars and semi-synthetic oils. If the oil is advanced or synthetic, the interval can be increased to 10,000 miles. In fact, it depends more on the engine condition than on the oil.

Can you put 10W-30 in a 5W-20 engine?

You should not use unrecommended oils in an engine with 5W-20 oil – 10W-30 oil has other parameters and properties. It’s thicker and inferior to 5W-20 in terms of proper operation at low temperatures. 10W-30 shows itself perfectly at high ambient temperatures but may not have enough fluidity for the type of engine under consideration.
