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.
