High mileage engines will need thicker oils. Thicker oils have additives such as conditioners, antioxidants, seal swells, detergents and friction additives that are engineered to take care of high-mileage engines. Gaskets, seals, and non-metal parts start decaying as an engine ages.
Is Thicker oil better for high mileage vehicles?
Is Thicker Oil Better For High Mileage Engines? A: Yes. An older, high-mileage engine can benefit from this practical method of improving oil pressure. If you don't hear knocking or serious mechanical noises from your engine, the heavier oil should extend the life of your vehicle by many miles.
Is high mileage oil thicker or thinner?
Drivers commonly use 10W-40 motor oil in vehicles with higher mileage because it is thicker while the engine is running, which helps lubricate older parts of the vehicle.
What oil is recommended for high mileage vehicles?
High mileage oil is designed for vehicles with more than 75,000 miles. Such oil features additives that help protect seals. This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it's suggested that you go with this type of synthetic oil.

When should I use 10W40 motor oil?
So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option. This higher viscosity oil is designed for hotter temperatures and can handle the added heat stress from the environment.
When should I use thicker motor oil?
There are some circumstances where drivers have used thicker oil in an engine. If, for instance, clearances between engine components have increased, gotten sloppy, a thicker oil can help to fill the void. Within reason, thicker oil maintains a better lubricant film between moving parts.
Is 10w40 good for high mileage?
Is 10w40 Good For High Mileage? The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.
Can I put 10w40 instead of 5w30?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What happens if I use 20w50 instead of 5w30?
A 5W-30 oil is commonly used in passenger cars for normal use throughout the year. A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle.
What happens if I put 10W40 instead of 10W30?
Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.
Which is better 10W40 or 10W50?
At 100ºC, the 10W50 has a viscosity of 18.1cS, the 10W40 is at 13.1cS. What this means is, at low temperature, they perform similarly, but at operating temperature, the 10W50 has better protection (higher film strength) than the 10W40.
Does 10W40 hurt 10W30 engine?
If you were to put 10W40 in an engine designed for 10W30, the “thicker” oil would lead to friction in the engine and an increased load on the oil pump. The car would have to do more work to get the oil around the engine block.
Can you mix synthetic oil with regular oil?
regular oil and advising whether mixing motor oil is okay. So, can you mix synthetic oil with regular oil? Yes. If it's something you do only occasionally, mixing shouldn't damage your engine.
Can I use 10w50 instead of 10W30?
Yeahh, you can use it. In 10w50, 10 is the viscosity of oil at low temperature and 50 is viscosity of oil at operating temp.
Which SAE grade would you recommend for an engine with high oil consumption?
Although some field tests have been carried out on xxW-20 oils, for the moment SAE xxW-30 oils remain the most recommended when it comes to saving fuel.
What happens if I put 10W50 instead of 10W40?
Can I use 10w50 instead of 10W40? If you have a modern engine that calls for 10W-40, it will not benefit from the increased protection of a 10W-50 oil. You should just use the manufacturer's recommended grade for your make and model of vehicle.
What does 10W30 mean?
The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.
What is 10W-40 oil used for?
This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.
Is 10w40 better for older cars?
When you put more pressure on your vehicle's engine at high temperatures, 10w40 will reduce wear and tear on the engine and make it more durable. 10w40 is also an excellent choice for older vehicles. As a result of the increased viscosity of 10w40, the engine's life was prolonged because it held metal to metal contact.
Can I use 0W40 instead of 10w40?
A thinner oil like 0W40 is better because it can reach engine components faster even in winter. 10W40 is better in the case of oil consumption. However, you should always use the recommended oil from your car manual at all times.
What does the W stand for in oil?
The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. The long answer:The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics.
What vehicle uses 20w50 oil?
20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.
Will 20w50 hurt my engine?
Will 20W50 Hurt My Engine? There is not a lot of traction to the 20W-50 viscosity. If used incorrectly, it can leave your engine aged or with sludge, excess friction, varnish deposits, and problems with oil burning and oil pressure.
Can thick oil damage engine?
It's best to use the oil viscosity recommended in the owner's manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.
