I have a 2007 2.4L Outlander which I purchased several years ago. I have always put 91 octane fuel in it, but recently when doing a deep clean I noticed a sticker placed out of normal sight on the petrol flap that said to use 95 or higher. The sticker has the logo of the garage I bought the car from, not Mitsubishi.
Am I doing harm to the engine by using the lower octane fuel?
If I change fuel type now, do I risk harm and what should I be looking for in terms of differences in the drive?

Hello, according to our data this engine only requires regular 91 octane.
it should be fine to continue with this fuel.
