Can you put a heavier weight oil in your car?
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.What happens if you put a heavier weight oil in your car?
Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.Is it OK to use a heavier weight oil?
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.Will 10w40 hurt a 5w30 engine?
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.Does it matter what weight of oil you put in your car?
There is no objectively “best” viscosity, or weight, for your motor oil. You should use the motor oil viscosity your car's owner's manual recommends.Pat's Perspectives - Thicker Oil (#2)
Can I put 10w30 instead of 5w20?
Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.Can I put 20w50 oil in my car?
Most modern car engines are not well suited for heavier oil like 20W-50, and it can damage your car's catalytic converters. 20W-50 oil does not have a reliable low temperature viscosity grade. It won't perform well in cold weather and will deliver below-average cold starts.What happens if you 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.Is 10w40 good for high mileage?
Designed for high mileage vehiclesMobil 1 High Mileage 10W-40 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils†), including: Cars. Trucks.
Can I use 10w40 instead of 30?
However, in general, I probably wouldn't recommend using 10w40 instead of SAE 30 in your lawn mower. Most lawn mower engines are designed to use oil with a viscosity rating of 30. Because 10w40 has a higher viscosity, your engine might not be able to lubricate itself as easily.Will heavier oil hurt my 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.Can I use 0w40 instead of 5W20?
Re: Can I use 0W-40 high performance synthetic oilThe 0 part means its got the cold-weather viscosity of any 0 weight oil, and will pour even thinner than 5W20 when cold. That's good.
What happens if you use 10w30 instead of 5w30?
Both 5w30 and 10w30 engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digits 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.Should I switch to thicker oil?
The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well. As long as you're not hearing knocking or serious mechanical noises from the engine, the heavier oil should buy you many more miles of service from your vehicle.What if I put 5w30 instead of 5w20?
If you use 5w30 oil instead of 5w20 when it is not recommended or approved by your owner's manual, it can void your car's powertrain warranty, reduce engine efficiency, and possibly even damage your engine in the long run. Hopefully, this helps!What happens if I put 5w40 instead of 5w30?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.Is 10W-40 too thick?
A low viscosity oil will move quicker through the engine to keep it lubricated and cool. Additionally, if your engine has a lower running temperature, 10W-40 motor oil might be too thick. Its higher viscosity at running temperature can reduce engine effectiveness as it'll need more energy to keep the engine operating.Which engine oil is best for hot weather?
The ideal motor oil for your car is one that can withstand the hottest temperatures in your region while still being able to flow when the weather is at its coldest. SAE 5W30 oil is suited to a broad range of temperatures, making it one of the most commonly used oils on the market.What oil is best for high mileage cars?

Is it OK to use 15w40 instead of 10w30?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40.Can you use 10w40 instead of 10w30 oil?
The short answer is yes. Because both oils are formulated to give the same performance, it will be safe for you to use either oil. Some differences between the two oils include viscosity and base oil.Is 10w30 better for high mileage?
10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.What happens if I use 20w50 instead of 10w30?
The main reason for using 20w50 is to slow down oil burning. If this is the case, using 10w30 would speed up the burning. I have had oil burners before, and used 20w50 in the summer, with no problem. But, your car will be hard to start in very cold weather with 20w50.When should I use 20w50 oil?
