Which is better 15w40 vs 15w30?

Which is better 15w40 vs 15w30?

15W-40 will lubricate older, worn out engines better and hold up better under hard use, though the 15W-30 may be better suited for newer engines with tighter tolerances that aren’t being pushed to their limits.

What is 50W oil used for?

20–50W you will notice is usually packaged in “racing, or high milage” formulas. In the the late 80s and 90s 20–50w was used a lot in racing motorcycle, Atv , high temp, endurance, high rpm applications . the thicker viscosity resists foaming, burn off, and can carry more heat away then thinner oils.

Can I use 10w60 instead of 15w50?

10w-60 is thinner when cold and thicker when hot. your guess is as good as mine, but I would stick with what aprilia recommends, or if you have issues with starting in cold mornings, go for 10w50.

Is 15W50 thicker than 10W40?

These viscosity index numbers are used to describe the relative thickness of oils for comparison. The 15W50 has numbers higher than the 10W40, therefore the 15W50 is thicker both at ambient winter test and engine operating temperatures.

Can I use 15W40 instead of 1030?

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.

What does the W stand for in 15W40?

In 15W-40, the first number on the left (15 here) represents the cold temperature viscosity and contains the letter “W” (which stands for winter, engineers are so creative). For example, a 5W-40 oil will be thinner in cold temperatures than a 15W-40, but at normal operating temperatures both oils will flow the same.

Can I use 20w50 instead of 15w40?

20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications. The difference between the two grades are just the specifications and for all practical purposes, in older vehicles without variable valve timing, the two grades of oil are interchangeable.

Is 15W50 thicker than 15w40?

15w-50 has a viscosity grade of 40. It is thicker and heavier as compared to 15w-40. It has been recommended for engines that have high performance. Most essentially used in motorsports, they are equipped to operate under heated and stressful conditions.

Which is better 15W40 or 15W50?

Yes, the 15w-50 oil’s viscosity is more than the 15w-40. While they both have a similar low-temperature (W-Winter) oil viscosity, the high-temperature viscosity, which is indicated by only a number is different. 15w-50 will perform better due to high viscosity at high temperature than 15w-40.

What is the difference between 10W30 and 15w30 engine oil?

Very little difference. The cold temperature cranking viscosity for 10W is 7000 mPa.s at -25°C, and for 15W is 7000 mPa.s at -20°C. So the diesel engine will be able to start more easily at a very cold temperature of -25°C with the SAE 10W-30 oil.

Is it safe to use 15W-30 engine oil in a car?

As per chemistry design of engine oil 15W-30 or 10W-30 does not matter, both the ingredients are same, but 15W and 10W here is the weather different, the alphabet W indicates weather. So use the engine oil for your car as per your climate ambien temperature you are living in. It should not make any damage to your cars engine.

Can I use 10W-30 instead of 5W-40?

So the diesel engine will be able to start more easily at a very cold temperature of -25°C with the SAE 10W-30 oil. The hot running oil shear points will be the same. It would actually make more sense to run 5W-40 in a diesel engine.

When did Chevron introduce the 15W-30 engine oil blend?
