If you have a 5W30 oil with an SAE rating of 15W-30 at operating temperature, it will have a thickness of 15 weight at cold temperature. At the same time, 5w-30 oil is typically used in warmer climates, making it better for engines that run at higher temperatures. To better understand, in a 5W-30 oil, the "W" stands for winter performance. 10W-40 can produce some gas mileage penalties during short trip situations in the colder winter months in Maryland, but the offset may be better ring seal. Only use what you need. The “30” represents the oil’s viscosity rating at hot temperatures. 0 or lower HTHS of a 5-30 under the hot conditions an air cooled engine experiences. At $3. Nevertheless, if you notice unusual signs after pouring 5w30, it’s advisable to drain it completely and continue with the recommended 5w20. 5w30, 10w30 and 0w40s. The only difference between these two motor oils is that the 5w20 is likely to thin out in extremely high temperatures while the 5w30 would survive such situations. The blend can provide adequate performance in moderate temperature conditions. Both 10W30 and 20W40 oils can withstand temperatures up to 100 degrees Celsius. Jeep recommends 5w-20.

If you use 10W-30 instead of 5W-30 in a vehicle designed for 5W-30, you may notice some differences in performance, particularly in colder temperatures. The lower viscosity makes 5w30 a better choice in cold weather. Using 10W40 in an engine designed for 5W30 can lead to: Delayed engine start: The thicker 10W40 might not flow as quickly as 5W30, especially during colder conditions. The ‘5’ in 5W-30 oil represents a slightly higher cold-temperature viscosity rating compared to ‘0W’. 10w30, the thinner 5w30 will circulate quicker, and flow through. No, not true. Engine oil with low viscosity and thickness can work under cold or low temperatures. Germantown TN 38138. Yes, 5w30 is an acceptable replacement for a 5w20-specified engine. It indicates that the oil is thicker and flows slightly slower at low temperatures compared to ‘0W’ oil. Therefore, 5w30 is superior to 10W30.
