Propane & CNG Conversion
Propane and CNG vehicle conversion specialists in Kelowna since 1987. Originally founded as Okanagan Propane & Automotive — our alternative fuel expertise runs deep. BC rebates available.
Book This ServiceOkapro Automotive's roots are in alternative fuel systems. When the company was founded in 1987, it operated as Okanagan Propane & Automotive, a name that reflects the core expertise that has distinguished this shop from general repair facilities for nearly four decades. While the shop has grown into a full-service automotive facility serving European, Asian, and North American vehicles, our propane and CNG conversion and maintenance capabilities remain unmatched in the Kelowna region. No other shop in the Okanagan combines this depth of alternative fuel experience with comprehensive general automotive service.
Propane autogas (LPG) is the world's most widely used alternative vehicle fuel. Over 25 million vehicles globally run on propane autogas, and for good reason. Propane delivers compelling economics: propane fuel costs have historically run 30–50% below gasoline prices in Canada, and the price stability of propane is generally better than gasoline because it is less exposed to crude oil market volatility. For fleet operators — delivery companies, utility crews, municipal services, agricultural operations — the fuel savings on high-mileage vehicles can represent tens of thousands of dollars annually. For individuals who drive significant annual mileage, the payback period on a propane conversion investment is often under two years.
Beyond economics, propane offers genuine environmental benefits. Propane combustion produces significantly fewer particulate emissions than gasoline or diesel, lower NOx emissions, and reduced greenhouse gas emissions. In terms of energy source security, propane produced in Canada doesn't carry the geopolitical supply risk associated with petroleum imports. British Columbia has supported alternative fuel vehicle adoption through rebate programs — our team can advise on current provincial incentives available for propane and CNG conversions.
A propane vehicle conversion involves replacing or supplementing the gasoline fuel system with a propane delivery system. Modern bi-fuel conversions allow the vehicle to run on either propane or gasoline — the driver selects the fuel or the system switches automatically when one tank is exhausted. This flexibility eliminates range anxiety and ensures you can always fuel up even in areas without propane fuelling infrastructure. Dedicated propane conversions, where the vehicle runs exclusively on propane, offer maximum system simplicity and cost savings but require reliable access to propane fuelling. Kelowna and the surrounding Okanagan have reasonable propane fuel availability.
The conversion process begins with a thorough evaluation of your vehicle to confirm it's a good candidate for propane conversion. Not all vehicles are equally well-suited — engine type, existing fuel system condition, intended use, and annual mileage all factor into the recommendation. We consider the vehicle's emissions certification, whether the conversion will maintain compliance with BC emissions requirements, and the practical infrastructure of propane fuel availability for your driving patterns. For fleet operators, we also consider maintenance schedules and driver training requirements.
Compressed Natural Gas (CNG) is another alternative fuel option we service. CNG vehicles run on the same natural gas that heats homes and businesses, stored at high pressure in purpose-built cylinders. Natural gas is the cleanest-burning fossil fuel, producing very low particulate and CO2 emissions. CNG is particularly compelling for vehicles that return to a central depot each day — the home-fuelling or depot-fuelling model works well for CNG because of the fuelling infrastructure requirements. Transit fleets, refuse vehicles, and large delivery fleets in Canada have adopted CNG widely. For the right application, CNG delivers outstanding operating economics and emissions benefits.
Okapro Automotive services existing propane and CNG systems as well as performing new conversions. Propane systems require periodic inspection of fuel cylinders (hydrostatic testing per Transport Canada regulations), fuel line condition, regulator function, vaporizer service, injector cleaning, and ECU calibration. We perform this specialist maintenance to keep alternative fuel systems safe, compliant, and performing optimally. Call us at (250) 861-4354 to discuss whether a propane or CNG conversion makes sense for your vehicle or fleet.

Our Process
Vehicle Assessment & Consultation
We assess your vehicle or fleet to determine propane or CNG conversion suitability. This includes evaluating engine condition, current fuel system state, your typical annual mileage, and local fuelling infrastructure. We calculate realistic payback period and annual savings estimates based on current propane pricing, and discuss whether a bi-fuel or dedicated system best fits your needs.
Conversion System Installation
We install the appropriate conversion system for your vehicle type. This includes fuel storage cylinders (installed according to Transport Canada safety standards), high-pressure fuel lines and fittings, regulator and vaporizer assembly, fuel injectors or mixer system, fuel selection switch, and ECU or fuel management system. All installations comply with BC safety and emissions regulations.
ECU Calibration & Performance Optimization
Modern propane conversions use sophisticated fuel management computers that must be calibrated to your specific engine. We calibrate injector pulse width, fuel trim tables, and air-fuel ratio parameters to ensure clean, efficient combustion on propane. Proper calibration is critical for both performance and emissions compliance — a poorly calibrated system will underperform and may fail emissions testing.
Safety Inspection, Documentation & Handover
Before returning your vehicle, we perform a comprehensive safety inspection of all fuel system connections, cylinder mounting, and system operation. We provide Transport Canada-compliant documentation for the conversion, explain the operation of the bi-fuel switch (if applicable), advise on propane fuelling locations in the Okanagan, and brief you on the maintenance schedule for your new system.
Frequently Asked Questions
Savings depend on your annual mileage and the current price differential between propane and gasoline. At typical Okanagan fuel prices, propane autogas costs 30–50% less per litre equivalent than gasoline. A vehicle driving 30,000 km per year might save $1,500–$2,500 annually in fuel costs. Fleet vehicles with higher annual mileage see proportionally larger savings. The conversion investment typically pays back in 18 months to 3 years for high-mileage vehicles.
Propane vehicle systems installed and maintained to Transport Canada standards are extremely safe — in many respects safer than gasoline systems. Propane tanks are built to withstand significant impact and pressure, with safety relief valves to prevent over-pressurization. Propane is heavier than air, so any leak dissipates into the atmosphere rather than pooling under the vehicle as gasoline vapour can. Propane also has a narrower flammability range than gasoline, meaning it's less likely to ignite accidentally. Our conversions are performed to the highest safety standards with regular inspection.
Most gasoline-fuelled spark-ignition engines are candidates for propane conversion. Diesel engines can also be converted, though this is more complex. Vehicles with very high existing mileage or significant engine wear are generally not good conversion candidates — the conversion investment requires the vehicle to run reliably for years to achieve payback. We assess each vehicle individually. Electric and hybrid vehicles are not candidates for propane conversion.
Transport Canada requires propane fuel cylinders to be hydrostatically tested every 10 years. Beyond mandatory testing, signs that your propane system needs service include: hard starting on propane, rough running or loss of power on propane, smell of propane (indicating a leak — this is urgent), excessive fuel consumption compared to baseline, or fault codes related to the propane fuel management system. Annual inspection of all fuel system connections and components is good practice.
BC and the federal government have periodically offered incentives for alternative fuel vehicle conversions as part of emissions reduction programs. The availability and specifics of rebate programs change over time. When you contact us about a conversion, our team will advise you on any current provincial or federal incentives for which your vehicle and application may qualify. For fleet conversions, there have been particularly attractive programs available through CleanBC and similar initiatives.
