The second series of testing was with a Yamaha 338 twin cylinder, twin carburetor snowmobile engine. Each carburetor is fed with a different gasoline oil mixture. This allows you to run one test with two oils under the same conditions. This procedure was conducted to measure carbon deposits. Racing Oil produced less deposits than all oils tested.
Some oils couldn' t even complete the test due to engine seizure.
The data obtained for the graph used on the TCR bottle is from the independent lab. Racing Oil took 18 months. Variations of the new oil while it was being developed have been run in outboard boat engines and snow-mobiles for field testing as well. All events are television on ESPN and ESPN2. The Series 2000 line is the next generation of oils resulting from new synthetic technology that has come out in recent years.
