Basics
- This page aims to cover the various ratios of Fuel (typically Ethanol Free Gasoline ) and 2-Stroke Oil for use in Total Loss Lubrication 2-Stroke Engines
- Common ratios will be covered and compared
- Impacts on Longevity, and Engine Deposits / Carbon Buildup (in particular on the Spark Arrestor / Muffler assembly
- Digging into information on (Malicious) Regulatory Compliance, and if engines REALLY ARE just telling people to use 50:1 for emissions, rather than actual design changes, will also be covered
Common Ratios
50:1
- 50 Parts Fuel, 1 Part 2-Stroke Oil
40:1
- 40 Parts Fuel, 1 Part 2-Stroke Oil
Other Ratios
- 25:1
- 32:1
- 16:1

- A Video by the YouTube Channel “Dave’s Small Engines” Titled “Will my chainsaw last longer if i use more oil? Is it safer? (25:1 VS 50:1 temperature testing ( ‘’’~15 Minute Watch’’’ )
- Main downside is the only thing they did was measure Cylinder (outer) Wall, and Muffler Temperature, both with a Laser Thermometer . The procedure was through + well thought out, but no investigation on Engine Deposits Carbon Deposits, or of Wear (On the Cylinder, on Valves, etc). Cut tests were alright, but more Project Farm esque jigs, or a Dynamometer test would be nice for quantification of power etc
