Advantages of autolube

1. Consistent lubrication and oil consumption is reduced greatly

2. More effective lubrication results because the oil enters the engine in larger size droplets

3. There is much less unwanted carbon deposited on the spark plugs, cylinder heads, pistons and exhaust system.

4. There is much less exhaust smoke

5. Refueling is simplified
