Its true - whether 20:1, 50:1 or just dumping it in your oil injection system (you lucky devil) oil, is really rad and completely necessary for most all internal combustion engines. I ran across a interesting test on a ski-doo forum that was a ASTM (American Society for Testing and Materials) run down on some common 2-cycle oils. This isnt some dude with a mullet who tossed a variety of oils in his chainsaw until it exploded. No, this is far more scientific than that. It shattered my illusions regarding one of my favorite oils - and made my cry. Telling someone their favorite oil sucks is dangerous, it can lead to deadly violence or at the least, a fistacuffs. That said, heres the results:
Wear Properties of Fluid Lubricants
Falex Pin and Vee Block Method
ASTM D2670
This is a comparison of anti-wear properties of popular 2 stroke snowmobile oils. This is an American Society for Testing Materials test that is a lubricant industry standard. This particular test incorporates 500 lbs of pressure on a steel pin and vee block for duration of 3.5 hours. There is a 5-minute break-in period with a 300 pound load. The overall wear is expressed in milligrams of lost metal.
The Results were as follows
Passed (listed in order of effecitveness):
#1 BG Hi-Performance Snowmobile Oil, Part No. 784S (15.2mg lost metal)
#2 Bel-Ray MC-1 (47.8mg lost metal)
#3 Bombardier XP-SII (66.3mg lost metal)
#4 Polaris Premium Gold Synthetic (82.5mg lost metal)
#5 Artic Cat Synthetic APV (112.9mg lost metal)
#6 Redline 2-Stroke Racing Oil (144.3mg lost metal)
#7 Maxima Castor 927 (156.4mg lost metal)
These Products Failed to reach the required testing pressure of 500 pounds.
