The lifespan of a gasoline engine machine often depends on the quality of the oil used. This is the case for the gasoline mower, which must be drained with high-quality, environmentally friendly oil.
Types of Oils
For the engine of a gasoline mower, you can use mineral oil, synthetic oil, or a blend of both.

Mineral Oil
Mineral oil is the one most commonly used by owners of gasoline mowers. It is derived from crude oil. However, mineral oil is a processed and refined oil to be less polluting. The oil, once treated, is stripped of most harmful compounds present in petroleum. Some additives are then added to make it cleaner for use and for the life of engines.

However, this oil remains one of the most polluting, but at the same time, the cheapest on the market. It can only be used in low-power thermal engines (2500, 4000 watts). Beyond that, mineral oil can pose a health risk.

Synthetic Oil
As one might guess, this oil has a purely chemical composition. Nevertheless, it is more efficient. More expensive than other oils, it is only used by those who can truly afford it. However, many are willing to make the sacrifice to keep their machine’s engine in good condition.
Synthetic oil performs its role as a lubricant regardless of the engine temperature. Its ability to maintain its fluidity at any temperature allows engines to start on the first attempts. It is also more economical, as using it means oil changes will be less frequent than with mineral oil.
Semi-Synthetic Oil
This corresponds to a blend of synthetic oil and mineral oil. This oil helps maintain the good condition of less temperamental engines. It can be obtained at an average price on the market. The composition, however, leans towards a larger percentage of mineral oil (65%) compared to only 35% synthetic oil.
Engine Oil Standards
The API standard (American Petroleum Institute) certifies the quality of engine oils. Oils are labeled with an S followed by a letter of the alphabet (SA, SB, SC, SD, SE…) The letters indicate performance. The further the letter is from A, the higher the quality of the oil.
The SAE standard (Society of Automotive Engineers) provides information on the fluidity of engine oil according to temperature. It indicates whether at low or high temperatures, the oil becomes heavier and does not lubricate well or retains its consistency. The following annotations are used depending on whether the oil is monograde or multigrade:
- 10 w (monograde);
- 10w40 (multigrade);
- 20w50 (multigrade).
In the annotation, the first number indicates fluidity at low temperature (cold) and the second indicates fluidity at high temperature. W stands for Winter.
