I recently bought the Rouge S AWD model. I filled it with regular and someone told me that premium is better as this increase the mileage and performance.I have switched to premium but did not noticed the difference.

I would like to know what type of gas that the owners are filling their Rouge, is it Regular or Premium? and what did you noticed on performance and mileage.

Regular, 87 as stated by the owners manual. The rogue is designed for 87 and anyone who tells you it'll benefit from anything else is full of it.

Save some money and just use regular.

Always use factory recomended fuel octanes. Using a higher or lower rated octane can reduce performance and reliability in the long run.
