When the piston expands from heat, space tolerances between the piston and cylinder walls become tighter and the likelihood of piston scuffing increases dramatically. Tightening within the cylinder increases friction and wear, robbing valuable power from the engine. The less friction within the cylinder, the more power the engine will produce.
Oil maintains a higher lubricity level than conventional petroleum oils.
Carbon build-up in the ring areas causes ring sticking, and on the spark plug causes plug fouling. Racing Oil is specially formulated to burn clean, ensuring optimal engine performance. This test was conducted on a Husqvarva TM chain saw model 266XP5.
