What is the next thicker oil than 10w30?

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.

Is 20w50 thicker than 10W30?

It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.

Can I put 10w40 instead of 10W30?

The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Viscous 10w40 is more viscous than viscous 10w30. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.

Is 15w40 thicker than 10W30?

While the viscosity of a heavy duty engine oil accounts for its contribution to fuel economy, it is the composition of the base oil and additives that protect your engine from wear, soot and acid. Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation.

Is 10W-40 heavier than 10W30?

The quick answer is 10W40 is a thicker engine oil than 10W30 at higher temperatures. Both have almost the same characteristics, and the only difference is the oil viscosity.

The importance of choosing the right engine oil quality and viscosity for your car or truck - VOTD

Which is better 10W40 or 20w50?

The 20th viscosity grade (i.e 20w50) is specifically designed for high temperatures situations, while the 40th viscosity grade (i.e 10w40) is specifically designed for cold-temperature situations.

Can I use 10W50 instead of 10W30?

If I'm not wrong, they'll both be the exact same thickness at 0°F but will perform differently at 212°F. Hence, simply put, the 10W30 will be thinner at 212°F (also read as the higher operating temperatures) than the 10W50.

Can I use 15W50 instead of 10W30?

It depends on the climb in the region you drive through. In a rather cold region I'd use the 10W30. In a warmer or even milder one, I'd use the 15W50. Which is wider in the usage range.

Can I use 15w40 instead of 1030?

The traditional 15W-40 oil is being replaced by the 10W-30 oil for heavy-duty applications. Fuel economy and power over can be improved by using a 15W-40 engine if it is designed and manufactured to use a 10W-30 engine. We lose less energy when the oil is sheared slower or the oil is thinner.

Which is better 15w40 or 10W40?

10W40 oils have a reputation for breaking down quicker than 15W40. This is because there are more viscosity indexes in 10W40 oil, owing to a larger difference in base and peak viscosities.

Is 20w50 thicker than 10W40?

10w40 oil is a popular all-purpose oil designed in many different engines. 20w50 (also known as 10w30) is another popular all-purpose oil used in engines. The differences between 10w40 and 20w50 are small, but they have something in common: They are thicker than regular 20w50 oil.

Which engine oil is thicker?

SAE50 is higher viscosity (thicker) than SAE40, and so on. Straight-weight oils come in a wide range of viscosities. But your car operates (ostensibly) in a wide range of temperatures. When your engine is running at operating temperature, it does not matter too much if it is summer or winter.

Can I use 20w40 instead of 10W30?

20w 40 is a thicker oil when compared to the original 10w 30 oil. So 10w 30 oil is going to flow better than 20w40 oil when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.

What is 20W50 oil used for?

20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

Is it OK to mix 10W30 and 20W50?

Can I mix 10W30 with 20W50? No, you'll be fine. I swear I didn't know. If you mix viscosity grades such as a 10W30 low-viscosity oil and a 20W50 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 10W30, but thinner than the 20W50.

Can thick oil damage engine?

It's best to use the oil viscosity recommended in the owner's manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.

Is 15w40 oil thicker than 30 weight?

Next, while hot, 15w40 will be thicker or have a higher viscosity than SAE 30. This is shown by the rating of 40 versus 30 between the two oils. When the engine is warmed up, SAE 30 will flow more easily than 15w40 would.

Can you mix 15w40 with 10W30?

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.

When should I use 15w40 oil?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.

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.

Which is better 10W50 or 20w50?

10w50 is thinner than 20w50 at low temp. So it will flow between every small parts and gives better cold start as compared to 20w50. First number lower than recommended and second number higher than recommended is good. You can go for 10w50.

Which is better 10W40 or 15w50?

At low temperature the 10W oil will flow better than a 15W oil. So the 15W-50 oil is “thicker” at cold temperatures than the 10W-40, therefore it will flow worse on start up; but being a little “thicker” it and maintains its viscosity at high temperatures better than the 10W-40.

Which is better 10W40 or 10W50?

At 100ºC, the 10W50 has a viscosity of 18.1cS, the 10W40 is at 13.1cS. What this means is, at low temperature, they perform similarly, but at operating temperature, the 10W50 has better protection (higher film strength) than the 10W40.

Which oil is thicker 15w40 or 20W50?

The higher the number the thicker the oil so in this case 15w40 oil will be a thinner oil. When you say which is better it depends on what the oil is for if it is for a car engine a oil which is 30 or 40 will better to use than a 50.

Is Thicker oil better for older engines?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well.
