At what mileage should you start using synthetic oil?

Certain brands recommend you have your oil changed every 3000 or 5000 miles. Other recommendations range from 7500 to 20,000 miles. Other factors that influence the time between oil changes include driving conditions and your driving style. via

Should I use 5w20 or 5w30?

The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency. via

Is there a big difference between 5w20 and 5w30?

When comparing 5w20 vs. 5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures. via

Can I use 10w40 instead of 5w30?
