Sentinel’s® 2 Stroke is a unique, premium quality synthetic two cycle engine lubricant specifically for use in two strokes engines at fuel-to-oil ratios of up to 100 to 1.

Additionally, SLC 2 Stroke was tested in this same procedure at one-half the level of lubricant prescribed for TC-W evaluations. Even at this lean ratio, SLC 2 Stroke met all the requirements of the TC-W oil test procedure. In fact SLC 2 Stroke was the first two stroke lubricant to achieve outstanding performance.
