Porsche, for example, acknowledges that any of its modern production cars can be run on regular fuel without the risk of damage.

A spokesman for Porsche North America, Tony Fouladpour, added a caveat. “If you want the car to perform at its maximum capability, the best choice would not be 87,” he said. “But we do not forbid it.”

For the extra $5 a tank, I'd rather have better performance and less risk of damage. My car performs bad enough as it is with the 10% Ethanol they have added to gasoline in the past year or two. I've noticed a significant drop in mileage and "seat of your pants pull" since this change as well.

So how many of you are using 87 in your Boxster?

I m not gonna do it. I open her up way too often to go a full tank on 87. I always run 91 from 76 or Chevron.

This is just an FYI just in case other members have been feeling the premium pinch.

I just did the calculation and its like $3.20 to put 93 verse 87 a tank extra. thats roughly 80-100 bucks a year, most you guys make that in a few hours
Go with 93 octane

12,000 miles annually and an average of 20 mpg, a car will consume 600 gallons of gas in a year. Even at 30 cents difference a gallon as quoted, the annual saving of using 87 octane gas is only $180. I think most car enthusiasts will not mind to pay that to gain extra 7 HP.

Fast and sophisticated as modern knock sensors, it is still a reactive process. It retards the timing only after a knock/ping has occurred. It is a “protective” feature like PSM. I am not sure it is meant to be activated regularly. The car’s computer should be re-programmed for 87 gas instead.

It comes down to just a sale pitch to bait those penny pinchers that like to drive premium cars but don’t like to pay for premium gas.
