2-Cycle Oils VOA Analysis

[SubieRubyRoo]

They increase burn time by burning as much fuel as possible before the exhaust port opens. Burning as much fuel as possible means less unburnt fuel going out the exhaust port and leaving residues.

Is anything like this used in race fuels or 4-stroke fuels?

@Rollins Why is a 5W30 engine oil (557224) even listed??

English is the preferred language for BITOG.

The guy used the opportunity to test the passenger car Shell Helix he uses for his own vehicle along with a Yamalube 2 imported and made in the Arab Amirates vs another Yamalube 2 sold by the official Yamaha Importer (turned identical despite the slight difference in labels).
The 2M is TC-W3-certified.

Also notice that some (but not all) later 2-cycle fluids have a 100°C viscosity hanging around 7.0 cSt, versus the earlier 10.0 cSt oils.
