Two-Stroke Vs. Four-Stroke Lawn Mower oil
There are two kinds of engines that lawn mowers are equipped with and these are the 2-stroke and the 4-stroke.
The 2-strokes required a combination of oil with the gasoline as combustion happens in one chamber.
However, there must be a proper combination of oil and fuel whenever you need to add fuel to your 2-stroke engine.
You cannot also combine regular lawn mower oil in the gasoline or use automotive oil because the detergents and additives in these oils can damage the parts in the combustion chamber.
With 4-strokes, mixing oil and fuel is not an issue because there are 2 chambers for each element.
You can also use all types of lawn mower oil including synthetic oil and even automotive oil included in your User’s Manual list.
The 4-stroke engines are now the most common types among the push mowers we use today.

Types of Oil Your Four-Stroke Needs
When it comes to 4-stroke engine oil requirements, we always recommend that you prefer first the type of oil specified in your user’s manual.

However, generic lawn mower oils are also safe to use because these are already formulated to use by all 4-stroke engine lawn mowers.
In fact, you can save more money with generic types because these are cheaper and easy to find.
Going back to the viscosity, there are actually four or five types of lawn mower oil today having SAE grades and these include the synthetic types.
Each grade conforms to viscosity or thickness of the oil and each type is blended to be convenient for lawn mowers on certain temperatures.
Common Grade Types of Oil That Are Easily Available
The SAE 30 oil is most commonly used by homeowners because they need to use their lawn mowers during summer.
The only problem with this oil is once the weather changes and the temperature drops below the freezing point, your lawn mower will experience a hard start.

Lawn mower manufacturers including Briggs & Stratton recommend that for new lawn mowers you have to change its oil 5 hours after the first run and 25 hours thereafter. This is to let the clean oil circulate properly around the crankshaft and the engine.
Moreover, if you are only cutting a small area of grass on a neatly cared for lawn.
Only mowing during spring or summer, changing oil every 50 hours would not be a problem.
Unless, of course, if your oil show signs of needing replacement.
