Does a car converted back from gas run more fuel-consuming?

Converted back cars from gas run more fuel-consuming. Introduction to gasoline-to-gas conversion: It involves installing a set of natural gas devices for ordinary cars, enabling them to switch between burning gasoline and natural gas, equivalent to dual-power vehicles. When the water temperature exceeds 60 degrees, the switch between natural gas and gasoline can be completed. When the natural gas is almost burned out, it can also be forcibly switched or run on gasoline. Pros and cons of gasoline-to-gas conversion: The advantages are full and clean combustion, less prone to carbon deposits, superior anti-knock performance, etc., and it does not dilute lubricating oil, effectively extending the service life of internal engine components. The disadvantages are that some cars converted from gasoline to gas experience a power drop of 10% to 20%, and the vehicle's self-weight increases, making the operation slightly softer than burning gasoline.
I have experience with this – cars converted to run on gas can indeed become more fuel-consuming after being converted back. The main reason is that the fuel system gets tampered with during the conversion process. If not properly restored, components like fuel injectors or fuel pumps may accumulate residues or get damaged, leading to uneven fuel injection and incomplete combustion, which silently increases fuel consumption. I’ve also encountered cases of improper engine tuning. If the ECU parameters were adjusted during the conversion but not properly reset afterward, the engine’s efficiency drops, and burning an extra liter per 100km is quite common. My advice is to thoroughly clean the fuel system, inspect the ignition system, and have a professional workshop perform the tuning before reverting. Cutting corners here could cost you more in the long run—poor conversion quality easily turns your car into a gas guzzler. I often recommend friends to get a comprehensive maintenance check just to be safe.
I personally tried converting my car to run on gas and then switching back to gasoline, only to find the fuel consumption increased. My old car ran on LPG for two years after conversion. When switching back, I did it myself for convenience, but residual gas remained in the fuel lines, causing uneven fuel injection and slight engine vibrations. Highway fuel efficiency was noticeably worse than before the conversion. It improved only after I spent some money at a professional shop to fix it. Conversion is a big deal—fuel lines and fuses must be handled carefully. Switching back requires thorough system cleaning; otherwise, gasoline won't burn cleanly, wasting money. Such issues often arise from aging wiring or incompatible conversion kits, especially in older models. If you want fuel efficiency and eco-friendliness, think carefully before converting. Don’t let unexpected repairs strain your budget. I now check my fuel lines regularly to ensure stable efficiency.
