1. How often should Hi-Tach be used?
In an engine, Hi-Tach should be used to replace 20-25% of the motor oil with every oil change.

2. Is Hi-Tach another type of "Slick 50"?
NO! Slick 50 and some 28 other brands on the market rely on P.T.F.E. (Teflon) to provide protection. Hi-Tach is 100% petroleum and can cause no harm to internal engine parts.

3. Because Hi-Tach appears so thick, will it make my engine hard to start?
No. Because a coating of Hi-Tach is always present and is more slippery than untreated oil, starting is actually easier.

4. Will Hi-Tach impede oil flow in cold temperatures?
No. First, the concentration used will normally be 20% in crankcases. Second, Hi-Tach assumes approximately the same viscosity as its host oil as the engine approaches normal operating temperatures.

5. Will Hi-Tach stop my engine from burning oil?
Hi-Tach will reduce oil consumption in many cases. However, you must remember that no chemical substance can rebuild a worn out piece of machinery.

6. Are there any instances in which Hi-Tach should not be used?
There are some. Automatic transmissions and torque convertors should be limited to an absolute maximum concentration of 10%. Automatic transmission valve bodies are made to operate on extremely thin fluids. Introducing heavier fluids will modify shift points and may inhibit valve opening and closing. Positraction rear ends and motorcycle oil bath clutches should not use Hi-Tach. These devices rely on clutch mechanisms which require a minimum coefficient of friction to perform. Hi-Tach will reduce friction to the point that they may not be able to function properly.
