I have one of the 2004 Subies with the stock turbo. I've been using 93
octane gas as recommended, which is normally no big deal, since I usually
only fill up every few weeks. But soon I'm going to be taking a cross-
country drive, and the extra cost of the premium gas is going to add up
over thousands of miles.
I'm not really a car expert so hopefully someone who knows about these
things can fill me in. The car has a knock sensor right? And a knock
sensor lets you use regular gas by changing some timings or something
right? I've heard it takes some of the power out of the turbo. Other than
that, is there a big downside?
Basically, the big question on my mind is if I can somehow save some $$$ by
using regular gas for my trip. I can't really imagine needing the turbo
boost when I'll be mostly on cruise control at 75. Is this practical?
