How to improve gas mileage

Post by Vinny » Thu Aug 30, 2018 6:39 pm

Greetings All,

I'm hoping that you could share your advice on how to improve gas mileage on my 2008 Taurus X. I did change the Motorcraft air filter and changed to full synthetic oil and filter. I have just reached 90000 kilometres.

I estimated that I'm getting a combined mileage of 21.5 miles per Cdn gal (4.4 lt)

Thanks in advance from Canada

Proper tire pressure, make sure the brake caliper slides, calipers are free, fresh angle gear oil, rear oil, fresh plugs.

Aside from that then you dive into modifications that improve Volumetric Efficency (VE)

VE is easiest improved by less restrictive air inlet and exhaust. So cold air intakes and larger freer flowing exhaust.

Free flowing muffler will not improve mileage as the small gains will be made at the top of the engine power range...that means 5-6k rpm.....90% of the time you will never drive close to that range .
The cold air filter at best will give you a 2-3hp gain again at the top of the range when volumetric efficiency of a regular air filter gets to restrictive.
Having a good quality clean regular air filter will maintain a sharp accelaration response.

My 2008 Taurus X still gets a 8.5-9l /100km with AC on long trips.
The fastest way to improve fuel economy is to shed more weight ie drop the rear seats if you don t use them, use lighter rims, keep clutter at a minimum.
Just keep the throttle body clean, change spark plugs and air filter, use syntetic oil and you should be good.
Any other solutions will render any savings worthless as they will by far negate any fuel savings with their high cost.

2005 AWD SEL

I bought my Freestyle with 88k I changed the gas filter noticed a better MPG also a few other things used a fuel injector cleaner 44K improved acceleration also installed a K&N air filter and replacing the FRAM filter.

Also switched over to full synthetic oil NOT BLEND.

Over all MPG improved a few MPG with better acceleration.

Scotty even do your car is almost identical with ours yours has a 3.0 l engine and CVT transmission, yours has 3.0l 200 hp ours a 3.5 l 267hp and a 6 speed transmission.
The 3.5l is more fuel efficient than the 3.0l, also the Taurus X gas filter is part of the fuel pump and can t be changed.

Another way to help is to keep the RPMs below 2000 as much as you can. Slower starts but great improvement.
