Auto LPG Inclusion Backed for 5-Year Age Limit Extension

New Delhi — May 7, 2026

The Indian Auto LPG Coalition (IAC) has asked the central transport ministry to include auto LPG in the proposed five-year age-limit extension for older vehicles. In a formal representation, the industry body argued that LPG-fueled cars are being left out of the policy even though they meet the same emissions and safety standards expected of CNG and electric options.

The proposed extension, currently under inter-ministerial consultation, would allow private vehicles that cross the existing age threshold to stay in service for up to five additional years. Owners would need to obtain a fresh fitness certificate, pass an emission test, and pay the applicable road tax. The policy is seen as a middle path between forced scrappage and unrestricted use of old vehicles.

The IAC’s core demand is simple: treat auto LPG on par with other clean fuels in the age-extension framework. The coalition stressed that LPG is not only a cleaner alternative but also one that offers immediate cost benefits. LPG produces lower particulate emissions than diesel, lower nitrogen oxide output than many older petrol engines, and lower lifecycle CO2 than both, according to the group.

“We aren’t asking for a new subsidy or a special incentive,” the IAC said in its statement. “We are asking for regulatory parity. If the age-extension route is meant to reward cleaner vehicles, LPG-fuelled vehicles should be allowed to use it.”

The comments were submitted during the current stakeholder-consultation round. Ministry sources said the transport wing is still reviewing responses, with a final notification unlikely before the close of the consultation window. The coalition’s representation also asks the ministry to confirm that certified LPG retrofits will be treated in the same way as factory-fitted LPG or CNG systems. That matters because many first-generation LPG cars were aftermarket conversions, and any ambiguity in their approval status could affect fitness renewal.

Analysts following the policy say the decision has wider implications. An older vehicle, whatever fuel it uses, is still an older vehicle. Engine wear and poor maintenance can offset fuel benefits. But IAC points out that the proposed extension already requires an emission test. If a car can pass that test on LPG, the argument goes, there is little reason to push its owner toward a more expensive conversion or replacement.

For owners, the practical benefit is cost. Retrofitting a petrol car with a certified LPG kit is less expensive than buying a new vehicle, and in many Indian cities the retail price of LPG is lower than petrol. The coalition says that including LPG in the extension would also support used-car buyers, especially in commercial and semi-commercial segments where operating cost drives decision-making.

The IAC wants the policy to create a clearer link between age-limit extension and normal fitness requirements. It argues that vehicles fitted with an approved LPG system should not face an extra layer of scrutiny beyond an ordinary emission and road-worthiness check. The same principle, the coalition notes, applies to CNG kits, and the two fuels should be treated equivalently under the rules.

There is also a fleet-level angle. Taxis and last-mile delivery vans, which frequently run on LPG in regions with fuel availability, would benefit from a predictable five-year horizon. Without that certainty, fleet operators may start registering older vehicles for scrapping or switch to fuels that don’t have the same cost profile. The IAC says this would be an unintended outcome of a policy intended to provide a transition, not a cliff.

Beyond India, the discussion is a reminder that LPG still struggles for policy recognition in many markets where electric and compressed-gas options are prioritised. In the United States, for example, propane autogas is used extensively in school buses and commercial fleets, yet it often sits outside federal and state incentive programs. The Indian proposal could become a test case for whether autogas is treated as a legitimate clean-fuel bridge or as an overlooked incumbent.

For now, the ball is with the Ministry of Road Transport and Highways. If the final notification includes auto LPG, the policy will likely accelerate interest in both factory-fitted and retrofitted LPG vehicles. If it doesn’t, the industry says the five-year extension will be less effective than it could be — and a cleaner, available fuel will have been left off a list it should never have missed.
