Should I use thicker oil in a high mileage engine?
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.
Does high mileage oil make a difference?It can help reduce oil consumption, smoke, and emissions from older engines. High mileage oil also works to minimize leaks and oil seepage.

Newer vehicles can utilize thinner oils for faster lubrication of new engine parts. In contrast, older, high-mileage engines benefit from thicker oils to prevent friction and oil loss.Is it OK to use synthetic oil in high mileage cars?
Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.Article first time published on askingthelot.com/what-is-the-best-high-mileage-oil/
Is 20W50 thicker than 10W40?
The numbers 20W50 refer to the viscosity of the motor oil, set by the Society of American Engineers. … The “50” refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick. Most modern oils are 10W40 or even 5W40.
Is 5W-30 good for high mileage?
5W-30 motor oil is the top viscosity recommendation by automakers over the past four decades for use in many vehicle types. … Furthermore, high-mileage 5W-30 motor oil is specially formulated for late model vehicles or newer vehicles with over 75,000 miles/120,000 kilometers.
What is the difference between 10 30 and 10W-40 motor oil?
The higher the number, the more viscous or thicker, the oil is at higher temperatures. This means that at 100oC, 10W30 engine oil has the viscosity of an SAE 30 single grade oil, and 10W40 oil has SAE 40 viscosity. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises.
What happens if I put 10W40 instead of 10W30?
So if you change your oil from 10W30 to 10W40 you should take care about the weather in your surroundings. Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Its totally safe you can go for it.
Which is better 10W40 or 15W40?
A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. … Hence, a car will start with fewer cranks when holding oil of a lower winter weight. 10W40 oil will perform cold starts better than 15W40 oil.
Why can't you go back to regular oil after synthetic?
Switching to synthetic oil causes leaks: Generally, switching to synthetic oil does not cause leaks. It is true that synthetic oil is thinner than conventional oil and therefore flows more easily. … You can’t switch back to conventional oil: Once you switch to synthetic, you are not bound to it forever.
What are the disadvantages of synthetic oil?

Can I switch to synthetic oil after 100k miles?
Yes, you certainly can. Just use the right viscosity oil, or a better range multigrade. If your car was recommended for 10W-30, you can use 5W-30 or 0W-30 for better lubrication in cold climates.
Is Full Synthetic Oil Better?
Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil.

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
What happens if I put 10w40 oil instead of 20W50?
The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.

What is the difference between 5 30 and 10 30 engine oil?
10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.
Is it bad if I put 5w30 instead of 5w20?
It is not safe to use 5w20 instead of 5w30. 5W20 is thinner and made for colder temperature. If you use 5w20 in warmer temperature instead of 5w30, you may have to deal with more friction and faster engine wear. Eventually your engine performance and longevity will be affected.
