Is it OK to use 15W40 instead of 10w30?
What Happens If You Use 15w40 Instead Of 10w30? Wear protection should not be sacrificed for fuel economy. The thinness of 10W-30 makes it less strong and more prone to oxidation than 15W-40. As a result, high quality additives are needed to protect as well as last for as long as 15W-40, which is why 10W-30 is needed.
What is the difference between 10W 30 and 15W-30?
The 10W-30 performed nearly 0.2 percent better than the 15W-30. That’s close to a 1 percent difference between the 15W-40 and the 10W-30.
Is 15W40 the same as 10w30?
Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.
Which oil is better 10w30 or 15W40?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40.
Can I mix 10W30 and 15w40?
you can mix the two without a problem, for Wisconsin, the 15w 40 would be a better oil in the summer and 10w 30 would be a better oil for the winter, if you drive the car in the winter! I have Rotella 15w40 weight oil in my LT-1 now and I just found a place that sells 10w30 which would be a better choice.
Can I mix 15w40 with 10W30?
When should I use 15W50 oil?
15W-50 has historically been a viscosity recommended for high performance engines, and is used today primarily in motorsports racing where engines are stressed due to high revving and heat.
Can you mix 10w 30 and 15w 30?
You can mix them with no problem. Read on the internet where a guy blow up his car doing that. you can mix the two without a problem, for Wisconsin, the 15w 40 would be a better oil in the summer and 10w 30 would be a better oil for the winter, if you drive the car in the winter!
Is it OK to mix 5W30 with 15w40?
You aren’t supposed to mix weights. If you don’t have anything else to replace 5W30, use only 5W30, according to the owners manual. If you are unsure about mixing different weights, check out Bob Is the Oil Guy.
Which is thicker 10W or 15W?
Motor oil grade represents the weight of the oil when cold, as well as at operating temperatures. Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures.
