What kind of oil should you use for a craftsman lawnmower?

Craftsman lawnmowers are one of the more popular lawnmower brands. There are both riding lawnmowers and push mowers from Craftsman. They are famous for their high cutting power. They owe much of this to their strong engines, further enhanced by the best motor oil. Using a suitable engine oil with the required specs and in the right amount is essential for any lawnmower. In the market, various oils are available for various working parameters. You must consider your environmental circumstances, workload, and engine type to decide on your situation’s most suitable oil. This article describes the details you must check when buying engine oil for your Craftsman lawnmower.

What kind of oil should you use for a craftsman lawnmower?

For craftsman lawnmowers, the most recommended oil grade is SAE 10W-30 with a capacity of around 18-20 Oz for climates where the temperature stays typically above 32 degrees Fahrenheit. SAE 5W-30 is preferred for colder climates as it improves cold starting due to its low viscosity. Synthetic-grade oils can be used when high-end performance is needed, targeting commercial use as it is more expensive.

To keep the engine in excellent condition, engine oil is crucial. Motor Oil is the lubricant that keeps the engine running and minimizes wear and tear. As time passes, small particles from the engine make the oil dirty and need to be replaced. Part of regular maintenance is to check the oil level and quality. Usually, it is advised to change the oil at least once per mowing season.


What kind of oil does your craftsman lawnmower use:

A Craftsman lawnmower is specific about its oil requirements. When you plan to replace the engine oil it is a good time to check the best type of oil for your situation. Use the following points to decide the best oil type for your situation.

● 1. Check the oil tank

You should first consult your user’s manual to find the oil type that is best for your Craftsman lawnmower. It will have some of the details. If you don’t have one, check your engine oil tank. Some models have some of the oil details noted on a small plate. This can give you some idea about the particular viscosity and working temperature range of the oil you should use. At the same time, you can check the tank’s condition and see if it needs some anti-rust treatment.

● 2. The company recommended engine oil

If you can not find the user manual for the company’s recommendation, the information can also be found online if you use the type and year of your Craftsman lawnmower. The exact amount and type of oil for your particular mower engine are important. Mostly, the oil type suggested for daily use is SAE 10W-30. For a craftsman lawnmower the capacity is around 18 to 20 Oz. If your mower is older, you should use a grade higher than recommended. But it is good to check with a professional for your specific situation.

● 3. Dependence on the environmental circumstances

The Craftsman 550 Series lawnmower manual specifies using detergent-type engine oil. The grades of viscosity normally depend on the air temperature. If you operate your mower mostly at a temperature above 32 degrees Fahrenheit, use SAE 30-weight oil. If you want to use the mower at a location where the temperature also gets below 32 degrees, use SAE 5W-30 multi-weight oil. Suppose your craftsman mower is used at a temperature between 32 and 122 degrees Fahrenheit. Use a 10W30 multi-viscosity oil.

The oil numbers represent the oil’s viscosity at different temperature ranges. Multi-weight oil can be used at warmer temperature ranges. But in that case, check the mower’s oil level more often than normal, as it often uses more oil. You can use the recommended oil type if you have a more recent Craftsman mower. You should use multi-grade thicker oil for older mower engines, as the engine has seen more wear and tear.

● 4. Different oils and environmental conditions

If the incorrect oil type is used in a lawnmower, worse case, it can damage the engine and lead to costly problems. Although car engines work by the same combustion principles, car oil should not be used in lawnmowers. Oils come in different viscosity levels, which describes the oil thickness. SAE 30 is a more viscous oil than SAE 20 oil. Check the Craftsman’s manual for the best engine’s oil viscosity level.

Colder engines require lower viscosity ratings for an optimum start. Hence, engine parts need less time wearing on each other without oil. Low-viscosity oils are thinner for that reason. While operating your mower in warmer temperatures, most high-viscosity oils benefit greatly because they can resist heat without burning out.

You can use similar-grade automobile oil when you need to add oil in an emergency but do not have the correct lawnmower oil. But generally, only use specific lawnmower oil as it has different additives targeting small engines like a lawnmower.

● 5.  Some synthetic oil recommendations

Craftsman lawnmowers can use synthetic oils as well. It is suitable for modern craftsman mower engines. Synthetic oil can cost three times more than conventional engine oil. However, it lasts longer than conventional oil because it can withstand higher temperatures and does not burn up quickly.

Synthetic oil in your mower can be left in the oil tank during storage because they are less prone to deposits and sediments, unlike conventional oils. One disadvantage of synthetic oil is that it does not lubricate new or rebuilt engine parts as well as conventional oil.

Synthetic SAE 5W-30 starts with low oil consumption and is typically used for all temperature ranges. Nowadays, synthetic oils for your Craftsman lawnmowers are highly suggested, as they can be used in cold and hot environments.

Step 6. Other parts where motor oil is used for greasing

The engine’s oil flows through several small parts of the engine. This helps to reduce friction and lower the temperature inside. It is mostly used in cylinders for lubrication and smoothens the working of shafts and valves.

When the oil gets crude over time, it can cause damage to the cylinders and worn-out the cylinder rings and the oil filter. The engine parts like cylinder walls, piston rings, lifters, and camshaft utilize this oil reservoir to work correctly.
