The answer to the question of whether you should use 5w20 or 5w30 motor oil depends on your vehicle, engine type, and driving conditions. Here’s what you need to know about this common auto maintenance topic.
You may have heard that you can use 5w30 instead of the normal 20-grade oil, but is this really recommended? The answer is no!
While both oils are rated for cold weather, 5W-30 is thicker at 212 degrees Fahrenheit than 5W-20. This means that while there are no issues with engine corrosion or rusting during cold seasons, there are more issues when the engine heats up to normal operating temperature.
If you’re looking for a thinner oil, the recommended grade is 5W20 instead of 5W30. The cold temperature optimal thinning properties will help your engine run more efficiently and last longer in warm conditions but don’t use this type when it’s below freezing because there will be too much friction that could wear down parts quickly- eventually leading to problems such as performance issues or even breaking down altogether!
When choosing motor oil for your car, it’s important to select the weight (viscosity) that is best suited for the climate and operating conditions you typically experience. 5w30 oil is a good choice for most drivers, as it offers a good balance of lubrication and fuel economy.
