Then going for a 0w20 or 0w30 oil will be an even better option. You should also check the owner's manual and read more about the recommended oils for your car. Here you can learn quite a bit more about which one should you choose when it comes to 5w30 vs 5w40. But from my experience, either way, you go you will not make any big difference. No, Porsche in Germany that has C20 standard use VAG 0w-20 and it is pretty cheap. €40 shipped for 5 L. Many oil analysis for VW engines that use 0w-20 so far are better in average than reported 5w-30. It may be related to the additives requirements for 0w-20 for VAG certified 508/509 and C20 are. N. Hot Weather Can I Use 0w20 Instead of 5w30? Accidentally Used 0w20 Instead of 5w30: Is It Ok? 0w20 vs 5w30 High Mileage Which Is Better, 0w20 or 5w30 Oil? When should I use 0w20 and when 5w30? 0w20 vs. 5w30 Toyota 0w20 vs. 5w30 Nissan 0w20 vs. 5w30 Subaru 0w20 vs. 5w30 Mazda 0w20 vs. 5w30 BMW 0w20 vs. 5w30 Ford 0w20 vs 5w30 Chevrolet a) Viscosity. 5w30 is 1.7 times more viscous than 0w20. A lower viscosity rating means it will flow better than 5w30 at the starting temperature. Thicker oils provide better protection against freezing. However, 5W30 gets thicker than both 0W20 and 5W20 in high temperatures because of the high viscosity rating. Jun 27, 2010. #1. I just bought a used 2009 Camry 4 cylinder which calls for 0W-20 or 5W-20 oil. It came from a car rental company and got Havoline 10W-30 for 36,700 miles, 5,000 mile change intervals. Rest assured that I will change the oil to Mobil 1 5W-20 very soon, but what damage would have been done to the engine for running the wrong oil Alternatively, you might be looking to reap the benefits of using a different type of oil. Generally speaking, it's perfectly safe to use 5w30 oil instead of 0w20 oil. Both oils have similar viscosities, and both perform well in a wide variety of engine types. That said, there are some slight differences between the two that might influence The first number, however, is different - "0", compared to "5". (Technically, these numbers are attached to the "W" too, but we'll come onto that in a little bit). Since 0 is less than 5 (if you know your math), it means that ( at a certain temperature) 0W20 is less viscous than 5W20. Or, if you prefer, it's thinner. What Is the Difference Between 0w20 and 0w30 Oil? Viscosity. A fluid's resistance to flow is measured by its viscosity, and this is the case with motor oil. The thickness Fuel Economy. Every engine can benefit from using either 0w20 or 0w30 motor oil. They have the potential to improve the Hot The resistance created by the cold oil is measured and converted to "centipoise" (or "cP"). Centipoise is a viscosity measurement unit. Higher centipoise values mean that a greater amount of energy is required to crank over the oil in cold temps. "0W" motor oils are measured at -35°C, while "5W" motor oils are measured at -30 However, the recommended motor oil for Subaru is 0w20 and 5w30. Hence, it will also depend on temperature; make sure that you use the correct motor oil at a specific temperature to avoid problems. 0w30 Vs. 10w40 In Mazda. According to Mazda Management, almost all of their vehicles are recommended to use 0w20 motor oil. y4gQR.
