Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher viscosity. Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.
Will thinner oils damage your engine?
Motor oil that is too thick will not flow into places where thinner oil will. That means metal-on-metal contact can wear away at engine parts. Oil that is too thin, on the other hand, might not have the sheer-resistance necessary for your engine. That could lead again to metal contact, along with reduced oil pressure.
Is it better to use thicker oil in 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.23 мая 2013 г.
Is it better to use thicker oil?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
Does thicker oil make your car slower?
yes it does affect performance. Just think about it, the oil is thicker than oem so it is going to require a little more force than usual working more than what it has to.
What happens if I put 10w40 instead of 5w30?
Originally Answered: What happens to engine if I use 10W40 instead of 5W30 (Manufacture recommended)? … If it is a modern engine damage will occur gradually . 10W40 is too thick and won’t flow easily when cold.
Is it OK to use 0w20 instead of 5w30?
0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. 0w-20 may be a recommended oil for certain conditions for your engine and may not be recommended for your engine.
Can using thick oil damage engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
What weight oil is best for high mileage?
Best Motor Oil For High Mileage Engines
- Valvoline (VV150-6PK) MaxLife 10W-40 Higher Mileage Motor Oil. …
- Pennzoil High Mileage Vehicle Oil. …
- Mobil 1 45000 5W-30 High Mileage Motor Oil. …
- Castrol 06470 GTX 20W-50 High Mileage Motor Oil.
Which oil is thicker 5w30 or 10w30?
10w30 is thicker then 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.
What is the most used oil?
The most common oil types include palm oil, soybean oil, canola oil and sunflowerseed oil.

Is 20w50 good for high mileage?
Considerations. The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.
When should I use 20w50 oil?
A 20W-50 oil is a heavier multi-viscosity oil appropriate for higher temperatures and higher loads, which require a more viscous oil. The minimum temperature this oil will pour at is 20 degrees Celsius, and its viscosity rating at 100 degrees Celsius is 50.
Does thicker oil affect performance?
Engine Oil DOES Affect Performance
Wonder no longer. The oil you choose for your car’s engine makes a difference in its economy and power production. … Your engine has to work harder to move internal parts with thicker oil in the crankcase, sapping energy before you ever have a chance to use it.
Does heavier weight oil leak less?
A heavier oil – conventional or synthetic – will slow down some leaks, but will never solve the problem. So yes, depending on the severity of your problem, it will slow the leak down.
