Because of wear, vehicles are more likely to consume engine oil as they age. Burning oil is a common problem, but when it is ignored, it can do major damage to your car’s engine.
Do older cars need thicker oil?
Many older, high mileage engines might face issues with oil pressure due to age and wear and tear. In this case, a practical method to improve oil pressure is to use a thicker oil, since the thicker oils have heavier base weight oil, which can help protect worn engine bearings well.
Should I use thicker oil in an older engine?
As a lot of oil burning is taking place and adding thicker oil won’t fix your engine, it will even worsen the situation. But there are many types of thicker oil to use in an older engine. Let’s discuss should I use thicker oil in an older engine or not!
Should I put thicker winter weight oil in my car?
It would especially not do your engine any good to put the thicker winter weight oil into the vehicle (assuming you are gaining on winter where you are at). The thicker oil when cold will not flow as well as the 5w-30, which means your engine will remain oil starved longer at start up, causing it to achieve more wear. Not good all the way around.
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.
What engine oil should I use?
Therefore some mechanics recommend using engine oil that is one level thicker than the recommended engine oil for engines that are considered old. For example, if the recommended 5W-20, you can change to 10W-30. The viscosity of the oil is able to withstand large component clearances
Does full synthetic oil burn faster?
Myth: Synthetics cause cars to use more oil. Untrue. A leaking engine will leak the same amount of either. Unless an engine is a real oil burner, it will burn less synthetic than regular.
Is it better to use synthetic oil or conventional oil?
Many automobile manufacturers use synthetic oil as a factory fill and synthetic oil is a recommended product by many car care experts. Many of the synthetic oil blends reduce friction better than conventional motor oil. This was a problem with a new engine break in period.
What are the disadvantages of synthetic motor oil?
Disadvantages of Synthetic Motor Oil Many of the synthetic oil blends reduce friction better than conventional motor oil. This was a problem with a new engine break in period. Synthetic oil does not hold lead in the suspension of the oil. This is a problem with older car engines that still need leaded gasoline to run in their engines.
Is synthetic oil good for rotary engine?
Synthetic oil is not recommended for rotary type engines. Synthetic oil does not react to temperature changes as petroleum based motor oil.

Does idling your car prolong the life of your engine?
The bottom line: Contrary to popular belief, idling your car does not prolong the life of your engine, rather it shortens it. Thankfully, your car doesn’t run rich the entire winter. It only happens when the gasoline is cold. Once your engine warms up to about 40 degrees Fahrenheit, the car transfers to normal fuel consumption rates.
Does idling your car in the cold waste fuel?
To get straight to the point, Ciatti said that idling your car in the cold not only wastes fuel, but it’s also stripping oil from critical components that help your engine run, namely the cylinders and pistons. Under normal conditions, your car engine runs on a mixture of air and vapourised fuel, gasoline in this case.
Why is winter driving hard on oil?
This sort of driving can be hard on oil because the engine isn’t allowed to completely warm up to operating temperature, especially during the winter in cold climate areas. When the engine is cold, it operates in a mode that richens the fuel mixture, which causes excess fuel to spill down past the piston rings and into the crankcase.
