How many miles should an oil change last?

Let us simplify it for you. Conservative estimates for oil-change intervals used to be as low as 3000 miles, before significant improvements in fuel-delivery systems, engine materials, manufacturing methods, and oil chemistry. Today, modern engines driven normally stretch intervals to 7500 or even more than 10,000 miles.

What is the recommended synthetic oil change interval?

Is 5W-30 oil better in winter?

Compared to other oils, the 5W-30 viscosity grade performs better during winters, preventing car engine wear and tear (thanks to anti wear additives). 5W-30 oil can operate in temperatures as high as 95°F, after which you should switch to a better high temperature oil viscosity grade.

What is the difference between 5W and 10W oil?

This number before the W shows how well the oil flows when used in lower temperatures. If you live in a cold-weather climate, both the 5W and 10W oil are going to be a good option for you.
