I used M1 5W30 in my mower with the Honda 160GCV consumer grade engine from purchase in 2000 until last year, when I ran out of my old formula M1 SL. Not only does this in-depth 10w30 vs 5w30 guide. Yes, It’s safer to mix 5w20 with 5w30. 10w30 oil is thicker and heavier than 5w30 oil because it has a higher viscosity at low temperatures. The add packs are pretty much identical, the base oil and VI content would be the biggest difference. However, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits. Secondly, you must know the vehicle’s manufacturer’s guidelines for oil viscosity. Aug 28, 2019. Location. It doesn't work that way at all. Better In Cold Weather. 10w30 can also be used. Viscosity is the level of a liquid’s resistance to flow. If you are a practical person, just go ahead - after all it is your car. If you put together these oils, it will boost up oil pressure when cornering at high revs. So whatever percentage of SAE 30 added is going to jack up the average above even what the 10W-30's normally run. 5w30 oil has a lower viscosity than 10w30, making it slightly thinner. The 5w30 when cold will still be thicker than the 10w30 when hot anyways so it doesn't matter. What oil Can you mix with 5W-30? These two motor oils are very similar in viscosity; hence, they might mix perfectly in your engine. Because of the viscosity, the 5w20 motor. The only difference between the two oils is the low temperature point, with the 5W30 oil functioning slightly better than the 10W30 oil. This means that if you want to, then you can mix 0w20 oil to 0w30 oil. This motor oil is used commonly in different types of vehicles. Below 40°F (4. Merely, it’s easy to understand that the lower the. Both the oils have the same viscosity (5W) though the viscosity index is different. When the engine is excellent, 10w30 motor oil has a viscosity of 10w. Mixing the viscosity of oils will not have any effect on the engine. What oil Can you mix with 5W-30? These two motor oils are very similar in viscosity; hence, they might mix perfectly in your engine. .

Do not, however, mix synthetic and normal oils (unless the synthetic's manufacturer specifically says it's OK). For instance, some automakers recommend against mixing synthetic and conventional oils. 5%. If they originally recommended 10W-30, they you can use 5W-30 or a mixture. 5w30 is also the thinner engine oil of the two at lower temperatures. The 5w30 oil will thin out the 5w20 oil and won’t flow as well in cold weather. In fact, the viscosity difference between 10W30 and 5W30 is essentially neglectable. You should now know that yes, you can use 10w30 instead of 5w30 for your car.

However, we do not recommend doing it because every engine requires different oil viscosity to function efficiently at temperatures. mix 5W30 and 10W30. Mixing one quart out of six doesn't seem like enough to degrade cold flow to take a 0W to a 5W. Jul 7, 2013. 2. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. The second viscosity rating is how thick the oil is at operating temperatures, which here in both cases is 30, the same. Synthetic 5W-30 can be used in all temperatures. If you are one of these car drivers, you should know this by referring to your owner’s manual. But at low temperatures, they show opposite reactions. of gas) to 50:1 (2-1/2-oz.

There are, as we’ll see later, pros and cons to doing so and mixing engine oil weights. In fact, because of its wider viscosity range and steeper viscosity curve, 5W30 likely does not thin out as much as 10W30 when ABOVE normal operating temperature. The 10w30 motor oil is suitable for engines using advanced fuels such as biofuel and biodiesel. It is best to use the same manufacturer and stay consistent with it. 3w36. Go with a 0w30 or 5w30. 5W20 will flow easier in cold/low temperatures to keep your engine parts. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Therefore, the 5w40 motor is not thick if it has a high viscosity. The two oils have different viscosities, meaning they flow at different rates. But the resulting oil should still be at least a 5W. Rotella ® T5 15W-40 also: Provides all the protection you expect from an SAE 15W-40 but in a synthetic blend heavy duty engine oil. The engine will not work correctly, and if you use the mixture for a long time, the engine will be significantly damaged. I'm using up my odds and ends. You WILL NOT get a 5W by mixing a 10W and a 0W. Quoting Stephen Miller from Shell: “For instance, if you mix viscosity grades such as a 5W30 low-viscosity oil and a 10W40 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 5W30, but thinner than the 10W40. 5w-35. These specifications are to be used as guidelines only. Yes, you can use 10w30 instead of 5w30 engine oil. 5w40 motor oil has a winter viscosity grade of five, for example. Both oils have almost the same viscosity and the same operating range. So if you live in a warm climate and find yourself with a bottle of 10W30 oil, don’t worry – you can use it without any problems. SAE 30 motor oil is only used for warm temperatures and 10w30 motor oil maintains its viscosity in both warm and cold temperatures. However, you need to know the right way to do this. If your running it day in and day out, I would use a HDEO 15w40, or 15w50. If you mix together a 5w-30 and 15w-50, the more volatile 5w-30 is still going to evaporate at high temps, and the resulting mixture will probably not flow quite a well as a 10wt at low temps. You can either add the lightweight 5w30 first and then top off with the heavyweight 10w30, or add the entire oil at once and then let it run for a few minutes before checking the level with a dipstick. Q. For instance, if you have the SAE 30 engine oil, you can mix it. Can I Use 10w30 Instead of 5w30 in Summer. This is because the ISO specifications are broad, and they overlap with SAE weights in some cases. Say we add a quart of 5w30 to 2 quarts of straight 30 weight. The 0w30 motor oil is a special kind of motor oil. For example: Valvoline Maxlife Synthetic.
