The quest for increased Fuel economy

I will be "tuning" the focus for better MPG. Any suggestions?
I did this with my daily driver (Lincoln towncar) with an intake and custom exhaust 2 1/2 center section , 2 1/4 tails, and high mileage synthetic blend sounds awesome and I get 21/34mpg city/highwa,y more if I pay attention.

Honestly the focus should be tuned from the factory with fuel economy and emissions in mind.

Allowing more air into and out of the motor will increase its efficiency - however everything I have read on the subject states that additional power does not relate to more miles per gallon.

I too am on a quest to increase MPG but I'm taking a different route - I am planning on decreasing the Coefficient of Drag. I plan on sheeting the underside of the entire car to reduce drag as well as dropping the suspension.

Which engine & trans. you have would help with mechanical suggestions.

That said, your easiest & largest gains with the Focus will probably come from removing excess weight (a pursuit taken to the extreme by some members, but just cleaning out the trunk helps), then selecting a high mpg tire set over a more performance oriented type & running an extra 5 psi. in the tires.

While newer tire designs constantly get better at balancing performance vs. mpg & long wear, "factory" types generally favor mpg while most replacements (even of the generic variety) favor increased traction over mpg & long wear.

So, in general terms, when shopping for "mileage" tires you will be looking for high tread wear numbers & lower traction ratings. The more "summer" type the better - almost all are "all season" these days, but for your objective the LOWER the winter capability the better.

The Town Car had a LOT more room for improvement in the intake & exhaust area than ANY of the Focus models, so beyond using a K&N type filter or a cold air intake system your main gains would only be from making sure the "tune up" items are up to snuff. (Plugs, wires, filters, belts, oil & filter etc.)

The other "obvious" area that commonly gets overlooked is the brake system. "Stickiness" in calipers, drum brake hdwe. or E-brake cables - even when not "bad" enough to require immediate attention will drop mpg noticeably.


Oh, By the way, the alignment info. in the Wheels Tires & Brakes area will be very helpful in increasing mpg & reducing tire wear if yours isn't set to those recommendations yet.

What engine do you have? That info might make it easier for others to help you out.
2011 SES 5spd #006 >> SR #213

What other people think of me is none of my business.
