Sorry for reviving a 5 year old thread, but I thought it's better than starting a new thread just for a post.
My mom's boyfriend
claims that on his 2010 Nissan Versa hatchback w/ 5 speed manual he gets about 10% better FE than with regular. He also claims premium (91 octane) is better for the internal components, keeping them clean and keeping the catalytic converter in top shape for the life of the car. He's a car salesman, started with Subaru & with GM now, so "
he knows cars".
I just get the regular gas from a brand-name pump since they have great points & rewards and 2% discount with the card. I basically get all the free car washes I need with the points.
Anyways, I've found something interesting produced by CBC - Marketplace. Hope you guys find this informative and I'm curious of your opinions.
