Best synthetic oils for using in a lawnmower engine

What is the best synthetic oil that I can use in my lawnmower?

Did you ever watch Star Trek: The Next Generation?

Because they were supposedly enlightened people and had no apparent reason to get plastered to help them forget all the horrible stuff they went through and sew Picard's crew would drink synthehol.

And it had no effect on the body in terms of inebriation.

What a waste.

They should make real homebrew

What is not a waste is synthetic oil for your lawnmower.

The best synthetic oil will offer the best engine protection at all temperatures as well as improved starting with less oil consumption. They will ideally help ensure your lawnmower is more likely to start in a cold climate!

What makes synthetic oil so good is that it is simply more 'oily' than mineral oils. As it is more 'slippery' it lubricates better and faster meaning it is consumed more efficiently.

If you are looking to use synthetic oil in your lawnmower (or another small engine like a chainsaw), then you are thinking smartly because synthetics also have properties which mean they tend to collect dirt and debris in the engine system better than traditional oils such as 20w50), meaning that when the oil is changed, more particulates are removed from your oil system. That can prolong the life of your small engine and it will perform better if as it will be less clogged by engine gloop.

Yes, that's a technical term, ask Gwyneth Paltrow...

One of the most popular synthetic oils just so happens to be produced by one of the most famous lawnmower engine manufacturers, Briggs and Stratton.

This author bought a Briggs and he will probably only ever buy their engines in the future because that brand represents assured quality. And you can say the same for their synthetic oil, SAE 5W-30 or 10W30 which is ideal for use in all air cooled 4-cycle engines.

Why was synthetic oil developed?

These lubricants were first synthesized, or man-made, in significant quantities as replacements for standard mineral lubricants (and fuels) by German scientists in the late 1930s and early 1940s because of their lack of sufficient quantities of crude for the needs of their military.

This was because of the need to operate machinery on the Eastern Front, which if you know a thing or two about that part of the world, is damn cold in the wintertime. Those scientists were trying to find ways to keep the oil fluid in the cold.

At the other end of the spectrum, there was plenty of research into finding synthetic oils that worked better than mineral based oils at high temperatures.

By the 1970s, synthetic oils had developed to the point they were suitable for commercial applications and were released for the automotive market and lawnmowers!

 A significant factor in its gain in popularity was the ability of synthetic-based lubricants to remain fluid in the sub-zero temperatures of the Eastern front in wintertime, temperatures which caused petroleum-based lubricants to solidify owing to their higher wax content.

The use of synthetic lubricants widened through the 1950s and 1960s owing to a property at the other end of the temperature spectrum – the ability to lubricate aviation engines at high temperatures that caused mineral-based lubricants to break down. In the mid-1970s, synthetic motor oils were formulated and commercially applied for the first time in automotive applications.
