Is thicker oil better?
And sometimes as engines add more miles, a little thicker oil works wonders. Well, in went 0W-40. Maybe it’s just me, but my engine seems to like it. Smooth, maybe even more power. Hard to believe. I feel I’m getting just as good mileage or better with this thicker oil. So since there is no warranty to worry about, is this acceptable?
Within reason, thicker oil maintains a better lubricant film between moving parts. Some have even used thicker oil in a leaky engine to prevent oil from seeping out. But really, thicker oil is not good for your engine. Not when “thicker” means higher viscosity than the manufacturer recommends.
Should I use thicker oil for old Pistons?
Using thicker oil for old pistons might not be a good idea. When a car gets old, it starts consuming more engine oil compared to the new ones, and when you add thicker oil to that engine, the situation gets even worse. That said, not all thicker oils are bad for weary engines.
Why is engine oil thinner than recommended?
Because the thinner the oil, the easier it is for the oil to enter into narrow gaps. So that this can cause the oil to burn in the combustion chamber. Therefore some mechanics recommend using engine oil that is one level thicker than the recommended engine oil for engines that are considered old.
Is it possible to increase oil pressure in an older engine?
Yes, because it is a feasible method to improve oil pressure in an older engine. Slightly more viscous oil will help you in protect worn bearings too. When heavier oil will be added to the engine, it will never leak and throw extra smoke out of the engine. Thicker oil can be the best motor oil for hot weather.
Is thicker oil better for an engine?
There is no definite answer for thicker oil is better for an engine. Because it depends on the engine-built technology. Modern advanced engines are designed with tighter clearances between the engine’s crank journals and main bearings. Therefore lower-viscosity thinner motor oil flows quickly and provides better lubricant film in metal parts.
What happens if oil is too thick?
If an oil is too thick, it causes additional load and reduces mileage, it also will not move into the smaller areas to provide lubrication nor will it move as quickly through the engine where it provides cooling.
What does a higher oil viscosity mean?
A higher oil viscosity number indicates a thicker oil. Where this is vitally important is in an engine’s bearing clearances. Older engines were built with much looser tolerances, which allowed oils such as 10W30 to be commonplace as an OE recommended oil in the 1990’s and before.

Is thicker oil better for Winter?
The “W” in that number stands for “Winter”, and the number before it (the “10”, in this case) is the viscosity or thickness. When the cold weather comes, you want a lower number, meaning thinner oil, which will smoothly coat the insides of your engine even in the most frigid weather.
What is the difference between thicker and thinner engine oil?
A thinner oil reaches the engine parts quicker, and circulates faster, while a thicker oil tends to adhere more easily to the engine parts, and will provide better lubrication when engine tolerances have deteriorated, or in severe-duty applications like racing or off-road engines.
Should I use a lighter winter oil weight?
– AMSOIL Blog Using a lighter winter oil weight when the temperature drops can improve cold starts and maximize wear protection at startup. Motorists sometimes ask if they should use a lighter weight (viscosity) of motor oil once winter arrives.
Is it better to use lighter or higher viscosity oil?
Higher viscosity oils tend to provide improved wear protection since they promote formation of a thicker fluid film on engine parts. They’re also more resilient to oil consumption than lighter viscosities. Bottom Line: Switch to the lightest winter oil weight your vehicle manufacturer recommends.
