The oil Viscosity results (SUS & cSt) and flashpoint were also below average indicating the oil was easier to ignite and became a thinner grade (even though it looked very dark).
Not only is it alright, full Syn in small engines is basically an actual 'lifetime' fluid in terms of resistance to breakdown and degradation and the only reason you'd need to change it would be from contaminants in it. Small engines are so low-shear/stress and subjected to so many less thermal cycles (for consumer mowers and such) that a Synthetic will barely degrade for many years. I'm largely fine with newer mowers advertising no oil changes as the factory fills were switched to Syns to handle it. There's an enormous difference between the longevity of the conventional SAE 30 or 10w-30 that were used until fairly recently and even any decent semi-synthetic.
I use super tech or rural king synthetic once a year in my small engines made by warren oil it’s good stuff for the price it don’t have to worry about it under performing
Small engines are very hard on motor oil. Air cooled engines run very hot and often do not have oil filters. Use synthetic oil ( Amsoil has synthetic small engine specific oil ) and change oil at the END of the mowing season. You don't want dirty oil sitting in the engine all winter. Also, use a fogging oil prior to storage.
Excellent advice. I changed the oil in the fall so any acid from the used oil doesn't work away at the engine over the winter. Fogging is a great idea, still a few months before I mow so I'll pull that spark plug out soon. Thanks for watching!
I love AMSOIL Small Engine Oil 10w-30. It’s a really good oil. The Honda engine in my lawnmower only takes about 20 OZ or 0,6 liter and the engine runs smoothly.
Thanks for an interesting video! The dealership that sold the lawnmower to me did the initial break in oil change. After that they did the first service on the engine. I live in Sweden. The first real service was after the first summer season. That equals about 50 hours of run time. The next service I did myself. I bought a Honda OEM spark plug and filter and then 10w-30 Amsoil Small Engine Oil. The motor ran smoothly the whole season and the oil still looks very good. I have a 4-stroke leaf blower that will get the Amsoil Small Engine 10w-30 oil too. Before the next oil change I will just as a precaution use Amsoil Power Foam too.
I'll have to give Amsoil small engine oil a try. I have heard good things about their oil since it is designed specifically for small engines which most often are air cooled and don't have the same performance characteristics that automotive engines have.
@@stevenroche9874 I get it from Sweden, Poland and Germany. Amsoil is pretty big in the general motorbike world. I can actually come across Amsoil cheaper than Motul, Liqui Moly, Mobil1, Castrol or any other oil brand.

Blackstone is A1 for oil analysis. Thanks for sharing your findings.
Thanks for watching!
It's absolutely alright to run synthetic oil in small engines.
Do an analysis after running Amsoil Small Engine oil for 100 hours.

No need for special Amsoil, just use Mobil 1 or any name brand full synthetic from Walmart
Conventional oils are used to break in the engine so the parts mate better. After that, synthetic oil use is okay. 😊
Great point!

Great tip, I'll have to check it out.
Excellent
Thank you!

@@OwenLucas You're welcome. Great content on your channel for an engine and motor oil enthusiast.
synthetic is fine to run in a small engine
Best not fine

@@OwenLucas It is also very common among cross and enduro enthusiasts.
I didn't know Amsoil is available in Sweden. Did you have it shipped from the USA or did you buy it locally?
