Today's gasoline is good stuff even if the octane rating is lower.

Correct. And I'd wager to guess it 99% of M6 owners never track their M6, especially in winter! You will notice a decrease in power and a decrease in miles per gallon. But so what if you notice a decrease in power from 575 horsepower to 550 horsepower and lose 5% fuel economy.
93 octane is typically 25% more costly. So is it worth spending 25% more to get 5% more fuel economy and to get increased horsepower that you will absolutely never use on the road? Your choice. But bottom line is your car will not be harmed with 87 octane. |
Yea I dont track and don't push the car that hard. Too many cops in my neighbourhood and I enjoy cheap car insurance.
Just worried about the well being and longevity of my S63. I'm out of warranty and not a believer in extended warranties so I just need to be on the cautious side.
