Mixing 10W30 with 10W40
Some say that mixing them is fine as long as you don't live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle. However, this is true only if you mix in a quart of the other type to your usual engine oil.Is 10W-30 same as 10W-40?
10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.What happens if you put 10W30 instead of 10W40?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.What happens if you mix two weights of oil?
Can oils of different grades be mixed? The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible.Which is thicker 10/40 or 10W30 oil?
The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.I can't believe what is inside Mobil1 oil filters
What is 10W-40 Good For?
The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot. This helps it lubricate older moving parts in high mileage engines while being less likely to leak.Can you mix different viscosity oils?
yes you can mix same brand and type oils with different viscosity and it will be fine as long as you don't mix them 50/50. If you mix 200 ml of oil with the rest of oil needed for your engine you will be totally fine.Can you mix 10W30 and 10/40 oil?

They're all pretty much made by the same companies in the same assembly lines anyways. Don't mix weights or synthetic and non synthetic. You'll be okay.Is 10w30 better for high mileage?
10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.Which engine oil is best for hot weather?
The ideal motor oil for your car is one that can withstand the hottest temperatures in your region while still being able to flow when the weather is at its coldest. SAE 5W30 oil is suited to a broad range of temperatures, making it one of the most commonly used oils on the market.Can I use 10/40 oil in my lawn mower?
Most lawn mower engines are designed to use oil with a viscosity rating of 30. Because 10w40 has a higher viscosity, your engine might not be able to lubricate itself as easily. This could lead to strain and wear on engine parts.Is 10w40 good for high mileage?
Designed for high mileage vehiclesMobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.
