Can I use 20W50 oil in my lawn mower?
The short answer is yes, you can use 20w50 oil in a lawnmower but results may vary. That's not the end of it though. This kind of oil is not designed specifically to be used in a lawnmower. 20W50 is actually a fairly specialized petrol engine oil formulated for use in engines made generally before 1980.
What happens if I use 20W50 instead of 10w40?
The numbers 20W50 refer to the viscosity of the motor oil. The "20W" indicates how quickly the engine will start when cold or in cold weather while 50 refers to the thickness of oil while the bike is running. 20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin.
Is 10w40 good for lawn mower?
SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends. Often 10W-30 or 10W-40, the same motor oil types that are used in vehicles, can also be used in a lawn mower.
When should I use 20W-50 oil?
A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.
Will 20w50 hurt my engine?
Is 20W-50 Oil Bad For My Engine? 20W-50 is not a very popular oil viscosity. In the wrong engine, it can lead to sludge, excess friction, varnish deposits, problems with oil burning and oil pressure, and even affect your engine life.
What is 20W 40 oil used for?
It provides strong oil film for lubrication and total protection to engine viz. protection from rust, corrosion, with reduced wear under a wide temperature range in air-cooled new generation 4 stroke motorcycles.
What is the best oil for a lawn mower?
SAE 30- Warmer temperatures, most common oil for small engines. SAE 10W-30- Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30- Best protection at all temperatures as well as improved starting with less oil consumption.
Does it matter what oil I put in my lawn mower?
10W30 is a common motor oil grade suitable for many lawn mowers. Your owner's manual will tell you the exact grade required, but in almost all cases 10W30 is the right stuff for a four-stroke engines. Any brand of oil that's suitable for cars or trucks will work fine in your mower.

Which is better 20w 40 or 20w 50?
20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions.
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.
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 the difference between 20W50 and 10W40 oil?
SAE is the Society of Automotive Engineers. They have set standards on oil. A 10W40 oil acts like a 10 weight oil when cold and like a 40 weight oil when hot. A 20W50 oil is a heavier grade both cold and hot
Why use 10W40 oil in summer?
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. So , if you will use 10w30 in summer then it is pretty obvious that there will be some wear and tear. Related Answer. Olivia Billon.
What is the viscosity of a 20W pump?
The 20W means that the cold cranking viscosity, CCS, is a max of 9500 cPs at -15 °C and the low temperature pumping, Pumping visc, is a max of 60000 cPs at -20 °C. The 50 means that the kinematic viscosity, KV, at 100 °C is 16.3 to 21.89, less than 21.9, and the high temperature - high shear, HTHS, viscosity at 150 °C is a minimum 3.7.
What is the max CCS for 10W?
The 10W means the CCS is 7000 cPs max at -25 °C and the Pumping visc is a max of 60000 at -30 °C. the 40 means a KV of 12.5 to 16.29 cPs and a HTHS, for a 10W it changes based on the number before the W, of 3.5 cPs minimum.
Is 10W40 viscosity the same as 10W50?
The 10W40 and 10W50 have similar viscosity at 0º (they’re considered to be the same class, not necessarily identical , but at operating temperature (100ºC) the 10W50 will have higher viscosity than the 10W40. The 10W40 has a viscosity index of 160, and the 10W50 has a viscosity index of 167 - meaning, the 10W50 has less variation in viscosity over the temperature range. The 10W40 has a higher flash point of 250ºC than the 10W50 (232ºC) - so it will withstand higher temperature than the 10W50.
Why do engines need zero W?
More modern engines with smaller gaps between moving parts would typically require a thinner oil. Modern engines often require zero W twenty or zero W sixteen oils to match their more precise machining, tighter tolerances and to help improve fuel economy by reducing power robbing pumping losses required by thicker oils.
Is 10W40 the same as SAE40?
So hot 10W40 is the same as hot SAE40, but when the oil is cold then straight SAE40 is WAY thicker (SAE40 is essentially 40W40).
Which is better, 10W-40 or 0W-40?
A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.
How much difference between 40W and 50W?
It doesn't make much difference though. At full working temps a 40w and a 50w are virtually the same viscosity…A 50w is between 12–14cst, a 40w is around 10–12 cst….a fractional difference.
What does 20W-40 mean?
In a 20w-40 for example the 20W bit and W (WINTER), simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the "W" numbers the better the oil's cold temperature/cold start performance.
Why use 5W-30 oil?
Many hot and fast motors now use the 5W-30 range of oils because the engines are super efficient and have very low and strict tolerances that require an oil to be thin enough to get in-between them.
What oil weights do new engines use?
New engines have an ideal range of oil weights they operate under from cold to hot. Therefore the manual will specific an oil, say 5W-30, that is the perfect range the engine designers think the engine will operate best under.
Why do modern engines last longer than they did 40 years ago?
The ONLY reason modern engines last longer than they did 40 years ago is because 40 years ago we were still using 20w-50. Now we are using 0w-30 and 5w-40.
What is 30SAE oil?
So in old engines the manual might specify 30SAE oil which was a compromise between oil thin enough to run in the engine when it was cold, yet thick enough to provide lubrication when the engine was running hot.
Why use lower viscosity oil?
The main reason behind the use of lower viscosity oils today is due to flowability causes less friction to moment lowering emissions. Click to expand... True. But, if it's an older engine, the toerances aren't as tight, and 5w30 will tend to be way too thin.
Can a 5W-30 be used in a small engine?
I have NEVER seen 5W-30 okayed for use in any air cooled small engine except for wintertime temperatures.
Is 10W40 oil thick?
10w40 is too thick at temp to lubricate properly and help with heat dispersion. Air-cooled engines are picky like that. I always use 10w30 in the winter in all my stuff, (but my car) and straight 30w B&S oil in the summer. When the temp doesn't get below 60 at night, you don't see a lot of advantages to multi-vis.
Does Briggs and Stratton use synthetic oil?
Briggs and Stratton has approved the use of 5w30 synthetic oil in all of there engines. Winter or Summer for all temperature ranges. The 5w30 synthetic wasn't approved by Briggs until a couple of years ago or so and is retroactive to older engines.
Can you use 5W30 in a push mower?
You don't want to use 5w30 in a push mower, it'll just burn up, because it's so thin. Straight 30w will be thick as honey when it's really cold (that's why it isn't reccommended for winter use), but thin right down at operating temp. The advantage, as you saw, is that it'll take a lot more heat.
Is 5W30 synthetic or synthetic?
ILENGINE said: briggs is now recommending 5w30 full synthetic in their engines. Other manufacturers use 10w30 due to some mechanical requirements (hydraulic valve lifters in Kohler Command) which will overpump and cause valves not to close if 30w is used below 50 degrees.
