Snowmobiles Prefer TC-W Quality Lubricant

Snowmobile field tests were conducted using a variety of two-cycle gasoline engines to evaluate deposit and scuffing control tendencies of lubricating oils compounded with several additive types. Results from these field studies showed that the BIA TC-W quality lubricant performs best in snowmobile engines. Specifically, this snowmobile field test which used higher fuel/oil ratios than those currently used showed that an ash-free amide additive was superior to either a low ash imide-sulfonate combination or an ash type sulfonate, and scuffing problems can be significantly reduced by the use of supplemental additives.
