I monitor mileage closely to figure out which gasoline gives me the best mileage. I noticed a lot of difference in my Aerostar, but I haven't driven the Focus long enough to figure out whose fuel works best with it. Give me a few weeks and I'll post my findings here in this thread.
25 city 75 highway
Near future mods will be geared towards mileage... I want 40
Right now I'm looking forward to getting an SCTX2, Marcy CAI, possibly exhaust, 3.41 gear (the big highway mileage booster), and possibly some ignition upgrades, but I doubt those add as much as is claimed from my previous experiences. I'm going to email Marcy when I order the stuff to see if cam alignment tools could void my warranty (probably) because as I recall from old school pushrod days- increasing lobe spread & cam retarding (I'm already retarded
)should increase fuel efficiency.
Some time next year I hope to have figured out how to plumb in a remote mounted low pressure turbo (3-5psi check www.ststurbo.com-
the *******s only do Chevy/Toyota/Honda- mostly trucks) in hopes to have my cake and eat it too.
