I refilled my gas tank last night, the last two tank fulls have been 91 octane gas. Bad habit I got into driving my bi-turbo Audi. This new tank of gas was 87 octane and this morning driving into work I notice the car needed a bit more gas pedal to get the same acceleration. The 3.6R certainly can use Regular gas, but it really likes 91 octane. having the higher octane gas allows the ECU to advance the timing and get a few more horsies.
I've been trying lately to get better gas mileage after seeing a news story on Nightline about Super Milers. Lots of coasting is the key. But I also love the sound of the 3.6R at WOT! What's a boy to do?! Vroom!
