Toyota Hycross & Maruti Invicto Owners Must Use Only 95 Octane Petrol – Why?

Toyota Hycross, Maruti Invicto Owners Warned: Use Only 95 Octane Petrol!

Why is 95 Octane Petrol Necessary?

Toyota and Maruti recommend that owners of their hybrid MPVs, the Hycross and Invicto, use 95 octane (RON 95) petrol. Using 95 octane petrol improves engine performance and helps prevent problems in the long run.

Toyota has updated the owner’s manual for Hycross models manufactured after March 2025. It clearly states that only 95 octane fuel should be used. Owners of the badge-engineered Maruti Invicto MPV should also follow this advice.

Dangers of Low Octane Petrol

Using low octane (e.g., 91 RON) petrol can damage the catalytic converter, which is one of the most expensive vehicle parts—costing over ₹50,000. Over time, this damage can lead to issues such as reduced power and lower mileage.

Different Specifications for Hybrid and Non-Hybrid

Only the hybrid version of the Toyota Hyryder SUV requires 95 octane. The non-hybrid version with the K15C engine runs smoothly on 91 octane. For the Hycross, Toyota has not specified different requirements for hybrid and non-hybrid versions—meaning both require 95 octane.

What is 95 Octane?

95 octane petrol is a premium-grade fuel with a high octane rating. It is designed for engines that demand high performance. It protects the engine, provides good fuel efficiency, and reduces pollution.

Catalytic Converter Performance

A catalytic converter is part of the exhaust system that converts toxic gases from the engine into less harmful ones. As emission norms get stricter, this component has become essential. A damaged catalytic converter can increase pollution and cause serious mechanical problems.

What We Want to Say Is…

If you own a Toyota Hycross or a Maruti Invicto, always use 95 octane petrol. This will keep your car performing well for a long time. Using low octane petrol can damage the catalytic converter, leading to costly repairs. So, spending a little more to use 95 octane petrol is a smart way to avoid bigger problems later.
