Can I use 10w40 in lawnmower?
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.
What happens if I use 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.
What happens if you put 10/40 oil instead of 5w30?
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.
Is 10w40 good for small engines?
Unless your engine calls for 40 weight oil, or is older and tends to burn or leak oil often, 10w40 oil is probably a bit too thick for most mowers. In addition to working harder, multi-grade oil could be seen as overkill.
Which is more fuel efficient 10W30 or 10W40 engine oil?
Technically, a lighter weight oil will provide better gas mileage as it’s lower viscosity makes it easier to move through the oil system. However, the difference between 10W30 and 10W40 will be indistinguishable.
What oil is thicker 10W30 or 10W40?
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.
Which oil is better 5w30 or 10W40?
The 5w30 oil will flow better at low temperatures than the 10w40 oil. This means that the 5w30 oil will protect the engine better at low temperatures, usually when the engine is just starting or during weather conditions such as winter.
What does the W stand for in 10W-40?
In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the “W” number the better the oil’s cold temperature/cold start performance.
Is 10W-40 Synthetic?
Semi-synthetic oils such as 10W40 have long been the standard. Their base is refined crude oil, which is then blended with additives. However the market is moving towards synthetic oils.
