November 9, 201015 yr hi, hope you guys doing great. : ) some questions: 1. i know the difference between manual and automatic LPG system, but does it has any difference in engine performance? 2. i have noticed from my friends LPG system that his top speed decreased after running the car for 2 years, is it because of the dirt inside the engine? Do we have to clean inside the engine every after some specific miles? thanks.
