"Slicker Oil Additive
Misty/Slicker 50-K is an oil additive that puts an anti-friction coating on the moving parts of your engines, drastically increasing performance and increasing wear protection. Measurable gains in lap times expected. Note: Do not mix with oil. Put oil in crankcase as usual less 1 ounce, then pour 1/2 to 1 ounce of Slicker on top. Use once every 3-4 oil changes for maximum performance. Do not use too much. Misty/Slicker should not be used with Super Green, as it may cause additive conflicts."
and, this is the one i like best!
"Fragrance
If you do not like the smell of certain additives you can add compatible frangrances to your oil and fuel. FHS provides special mint, lemon, strawberry and tropical smells to your choice which you can safely use in your oil and fuel without being worried to change the characteristics of them."
