Should I use thicker oil in a high mileage engine?
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..
Do high mileage oils work?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. … In addition to having seal conditioners, high-mileage oils usually boast more detergents designed to clean out sludge inside the engine, plus other additives meant to reduce wear on moving parts.
Is 5w30 good for high mileage?
For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40. If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.
What happens if you put thicker oil in your car?
The higher the number, the thicker the oil. Thicker oil protects engine parts better than thinner oil under tough conditions. For instance, if you’re driving in Arizona in the middle of summer, a 20W-50 motor oil would protect your engine better than a 5w-20 viscosity.
What is 10w 30 oil used for?
For Example: 10W30 This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.
Is 10w30 better for high mileage?
Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.
Does 10w40 hurt 5w30 engine?
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.
Is SAE 30 thicker than 10w40?
The viscosity of hot oil is measured using different test parameters than when the oil is cold, so the numbers after the “W” don’t relate to the numbers in front of the “W”. The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
When should you use 10w40 oil?
When to Use 10w30 vs 10w40 Using 10w30 oil in cold weather will help reduce excessive oil temperatures and drag as the engine warms up. Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.
Can I use 10w 40 instead of 10w30?
Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles. But, if you are still not sure what to use, talk to your local mechanic or check the vehicle’s manual.
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
What does the 10w 30 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 labeled 5W30, which has a thinner viscosity when the engine is cold at 5W.
What is 10w 50 oil used for?
10W means that the oil is suitable for winter temperatures down to -30 °C. The second part of the SAE class, the number ’50’, indicates the kinematic viscosity at 100 °C. With the ADDINOL POLE POSITION 10W-50 this is in the range of 16.3 – 21.8 mm²/s and can therefore also be used in high-performance engines.
Does thicker oil increase oil pressure?
Yes thicker oils will increase oil pressure, but will reduce engine horsepower. Excessive oil pressure may explode the oil filter, damage seals, blow out oil passage plugs or even damage bearings.
Is Thicker oil better for 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.
Is 10w oil better than 5w?
Automakers usually specify a 5W-20 or 5W-30 oil for colder temperatures, with a 10W-30 oil as optional for higher ambient temperatures.
When should I use 10w30 oil?
At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.
Can I use 10w 30 oil instead of 5w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Which oil is better 5w 30 or 10w 30?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.
What happens if I put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
What happens if I use the wrong oil?
You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.
