What’s thicker 15w30 vs 15w40?
This is not very relevant when it comes to lawn mowers since you probably won’t be mowing in freezing temperatures, but it is worth noting that SAE 30 will be thicker than 15w40 when cold. This is because 15w40 is a multi-grade oil with additives that lower its viscosity when cooled.

Do they make 15w30 oil?
Delo SAE Heavy Duty Motor Oil 15W-30, 1 Gallon, Pack of 1.
Can you use 10w30 instead of 15w40?
Since 10W-30 is thinner than 15W-40, 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 10W-30 to protect as well and last as long as 15W-40.

What’s the heaviest motor oil?
In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of 60, which is the thickest oil.
Is 15w40 good for diesel engines?
15W-40 is a very common viscosity grade for diesel engine oil. GTX Diesel is a 15W-40 diesel engine oil formulated to help extend engine life.
Why do diesels use thicker oil?
Higher the viscosity thicker the oil. It is believed that thick oils are better at maintaining film strength and oil pressure at high temperatures and loads. This oil is majorly made for the rare cars which are with diesel engines that burns oil excessively. It is a premium high performance mineral.
Which engine oil viscosity is best?
The smaller the number, the better it will flow. A 5W-30 will flow easier than a 10W-30 at start-up temperatures and a 10W-30 will flow more easily than a 10W-40 at normal engine operating temperatures.
What is 15W 40 oil used for?
MobilMobilMobil 1 Extended Performance is a synthetic oil designed to keep your engine running like new even during today’s longer service intervals. With Mobil 1 Extended Performance synthetic motor oil, you get proven protection up to 20,000 miles, guaranteed.https://www.mobil.com › our-products › product-faqsMobil 1™ and Mobil Super™ oil FAQs Gas Engine Oil 15W-40 is a premium fleet engine oil specifically formulated to provide reliable protection for trucks and buses using Compressed Natural Gas (CNG) or Liquefied Natural Gas (LNG). Mobil Gas Engine Oil 15W-40 is formulated from high quality base stocks and a balanced additive system.
What does 15W 30 mean in oil?
In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine’s normal operating temperature.
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.
What happens if engine oil is too thick?
If the oil is too thick (aka, the viscosity is high), your car may not start in cold temperatures (cold weather places more strain on a vehicle in any case). When this happens, the thick liquid can’t properly lubricate every part, and it creates enough resistance to impair the most important function–ignition.
What oil is best for diesel?
If you’re looking for the best oil for your diesel engine, you can’t go wrong with synthetic oil. Synthetic oil is designed to withstand extreme temperatures and conditions, making it ideal for use in diesel engines. It also provides superior protection against wear and tear, helping to extend the life of your engine.
Is 15w40 good for hot weather?
In tropical weather, most OEMs still recommend multi-grade products, such as SAE 15W-40, because the lubricant flows faster through the engine than a pure SAE 40 even at higher ambient temperatures.
What is the best oil for diesel engines?
Which oil grade is best for diesel engine?
5W40: This oil is considered to be good for diesel cars. It can perform equally good as 0W40 albeit not in cold weather conditions. 5W30 or 10W30: Ideal for modern petrol engines.
Will thinner oil damage your 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.
Is thicker engine oil better?
Within reason, thicker oil maintains a better lubricant film between moving parts. Some have even used thicker oil in a leaky engine to prevent oil from seeping out. But really, thicker oil is not good for your engine. Not when “thicker” means higher viscosity than the manufacturer recommends.
Can I use 15w40 in petrol engine?
Vehicle & Fuel Types
Semi Synthetic 15W-40 is suitable for use in passenger cars, 4WDs & light commercial vehicles and is compatible with Petrol/LPG (Dual Fuel), E10, Diesel (without DPF) and most other conventional fuels.
Which is better 5W-30 or 15w40?
Probably not. 15w40 is usually used in diesel engines and has a much different additives profile. 5w30 is usually used in gasoline engines. Diesel oil is designed with high antiwear additives such a ZDDP.
What happens if you put 10W40 instead of 5w30?
What will happen if I put 10W40 instead of 5w30? Being a thicker oil 10W40 can harm your engine if your engine requires a thinner oil. Although a bit of interchange in engine oils can be good, it is highly recommended not to use one to replace another.
Is thinner engine 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.
How often should you do an oil change on a diesel engine?
every six months
The average recommendation for diesel pickup oil changes is between every 5,000-7,000 miles or every six months on vehicles that perform moderate towing. If you do not tow, or don’t tow very often, you may be able to go even longer. If you are frequently towing heavy loads, you may need to change the oil sooner.
Why is my diesel engine oil so black?
The soot forms in cooler parts of the combustion chamber until it impinges on the cylinder wall and is scraped into the oil sump courtesy of the pistons leading to a faster blackening of the oil.
When should I use 15w40 oil?
ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.
