Why You must Use the Right Oil?
Oil acts as a lubricant that helps the proper functioning of intricate parts of the motor. It drastically reduces the friction between the parts which in turn cools it down to avoid overheating things up.
Very heavy oil or the wrong oil can gum up the piston, valves and other internal motor parts hereby causing the motor parts to move slower than normal.
Subsequently, using lighter oil will not lubricate the internal parts well enough hereby causing overheating of the piston and valve.

How to Check the Oil level of Your Lawn Mower
To check the oil level of your lawn mower, take the following steps:
- Apply a little clockwise pressure to the dipstick cap to twist it open
- Remove the cap and clean with a rag to make for clear reading
- Place the clean dipstick cap back into the groove ensuring that the teeth of the cap match the groove top.
- Apply some pressure again by turning the cap anticlockwise to lock it.
- Now remove the cap again as before to view the oil level
- Pour oil via the groove in ounces at a time if oil levels are low.
- Allow some time to elapse before rechecking oil levels.
When is the Best Time to Change Lawn Mower Oil?
The right time to change the oil in engine largely depends on manufacturers specifics. Some engines are designated as “no–oil change” meaning all you need do is check and add. Consult your owner’s Manuel for specific instructions on when to change the oil. Ideally, you should change the oil once every spring or summer mowing or after every 55 hours of mow time, whichever one comes first.
Can I Mix Oil with Gas in a Mower?
Most residential lawn mowers are made with 4 cycle engines that move gas and oil into separate reservoirs. So don’t attempt to mix them up together. Consult the manufacturer or Manuel to find out the engine type of your lawn mower.
