Toyota has revised its fuel recommendations for select hybrid models in India, advising the use of RON95 or higher-grade petrol starting with vehicles manufactured from March 2025. This update has been reflected in the latest owner’s manuals for the Toyota Innova HyCross and Urban Cruiser Hyryder.
For the Innova HyCross, Toyota has not differentiated between the gasoline and hybrid variants, implying that the RON95 fuel recommendation could apply to both powertrains. Meanwhile, the Urban Cruiser Hyryder and its sibling, the Maruti Suzuki Grand Vitara, now require RON95 fuel specifically for their hybrid versions. The guidance is aimed at ensuring optimal engine performance and avoiding potential long-term damage, particularly to critical components like the catalytic converter.
The non-hybrid variants of the Hyryder and Grand Vitara can continue using RON91 petrol, which has been the standard fuel for most Indian vehicles. However, Toyota has cautioned that using lower octane fuel in hybrid versions may lead to premature wear of certain engine parts.
Maruti Suzuki’s premium MPV, the Invicto, which shares its platform with the Innova HyCross, will also follow the same updated fuel requirement for units produced after March 2025.
While RON95 fuel typically comes at a higher cost, Toyota’s recommendation highlights a shift towards enhancing long-term reliability and efficiency in its hybrid powertrains. Though RON91 fuel might still run the engines, doing so could come at the expense of part longevity and performance.
