Is 10w40 better than 10W50?
The difference between 10w40 and 10w50 is how thin the oil gets when it’s hot, 10w50 oil won’t thin out as quickly as 10w40 when oil temperature goes up, but it also might be too thick during regular running in cold temperatures. Company recommends 10W50, which is freely available. Don’t use different grades.
What is 10W50 oil used for?
10W50 oil is a high-performance engine oil that offers outstanding engine reliability and temperature stability under extreme driving conditions. It’s used for a wide range of motorsports and modern engines with turbochargers.
Which is better 10w40 or 15w50?
Because it is thinner, the 10W40 flows well at high temperatures leaving no residue in the engine. The 15W-50 engine oil is better for use during Winter than the 10W-40. 10W -40 is denser or thicker than what most engine manufacturers recommend. 15W, on the other hand, increases wear fuel consumption and reduces power.
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.
What is 10W 40 oil used for?
diesel engines
SAE 30 vs 10w40 (The Short Version)
10w40 is an oil that is mostly used in diesel engines and motorcycles. This is because 10w40 is slightly thicker when hot, and also rated for use in cold temperatures.
Should I use thicker oil in an older engine?
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 thicker oil damage my engine?
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.
What is 10W-40 oil used for?
When should I use 15W-50 oil?
15W-50 motor oils
15W-50 has historically been a viscosity recommended for high performance engines, and is used today primarily in motorsports racing where engines are stressed due to high revving and heat.
Is 10W40 good for summer?
They are both available in pure conventional form or as high-quality synthetic grades. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.
Can I use 10W50 instead of 10W40?
In short, you can use 10W50 if your vehicle is specified with a 10W40 grade, at the expense of a little less power and mariginally lower fuel efficiency, but using the 10W40 on a vehicle for which 10W50 is recommended, will cause faster wear.
Is 10W40 good for high mileage?
Designed for high mileage vehicles
Mobil 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 too thick oil damage engine?
Not only that, but the engine will waste energy pumping the thicker oil, reducing fuel economy. Since thicker oil doesn’t transfer heat as well as thinner oil, operating temperatures will increase, possibly leading to accelerated chemical break down (called “oxidation“) and harmful sludge and deposits.
Is 10w40 good for high mileage?
Is it better to run thicker oil in older engines?
Can I use 10W50 instead of 10w40?
Can I use 10W-40 instead of 15w50?
Is 10W50 a synthetic oil?
MADE WITH TOP TIER ADDITIVES
Steadfast 10W50 is a blend of high quality synthetic base oils and special additives that protect against high temperature oxidation, wear, and shear breakdown.
What is 10W-40 used for?
Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.
Is Thicker oil better for an older engine?
Is thicker or thinner oil better?
Engine oil viscosity
Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.
Will heavier oil hurt my engine?
What oil is 10w40 for?

What is 15W-50 oil used for?
Can I use 10W 30 instead of 10w50?
Hello, If I’m not wrong, they’ll both be the exact same thickness at 0°F but will perform differently at 212°F. Hence, simply put, the 10W30 will be thinner at 212°F (also read as the higher operating temperatures) than the 10W50.
