Some of the most common types of oil include 5W30 and 10W30. 5w20 is thinner to increase fuel economy. TLDR: mechanic put 5w30 instead of 5w20 because the milage is high and recommend oil changes every 3k miles instead of every 5k miles. The 5w30 has more viscosity index improvers vs the 10w30 so technically the 10w30 would have more oil that lubricates the engine. One cycle of. However, 5w20 will perform better in cold temperatures compared to 15w40. They will blend perfectly. What happens if I use 10w30 instead of 5w30? If you use 10w30 oil in a car that’s designed for 5w30, the oil may not flow as easily at lower temperatures. 8. So, let’s start with a table comparing both the engine oils in different parameters under warmer conditions–. Therefore, the 5w40 motor is not thick if it has a high viscosity. There is no major issue should you use 10w30 instead of 5w30. In other situations, you can use 5w40 motor oil in the same engines with the same results. Mixing the two will dilute the characteristics of 5W-30 and likely result in poor engine performance. Pop, your conditions probably are not cold enough that you would notice the difference in pull-starting between a SAE30, 5w30 or 10w30 w/ this type of equipment. Mixing the viscosity of oils will not have any effect on the engine. 00 a quart, why not continue to follow the manufactures recommendations.
