Philip,

How cold is it where you are in SoCal? Or perhaps you are in a colder area?

I spent two weeks housitting (and chicken-sitting etc.) in the Cascades, just high enough to see snow several times during the stay
I have been starting down to 30* on Biodiesel with no block heater, once fired up everything is great.

VERY nice today... 67 degrees and clear. Right now, (7:00pm, 48 degrees). The coldest overnights of late have been 37.

The fuel experiment is -not- about cold starts, rather MPG in colder ambients using overly winterized fuel, very heated air, and altered fuel timing.

yep...i do have about an extra 100hp though....and a bit extra weight..and 2 more wheels to drive..and another diff..and another gearbox....but still 39mpg!!!....

the new landrover using the ford v8 diesel is getting high 30's though and 300hp!!!that must be some engine!..(and american too!!)

Happy New Year to you, Zen.

As I have come to expect, you throw figures about with the reckless abandon of an astronomer. Amusing. :P

1) We know your turbo addition did not provide an "extra" 100 hp.

2) Ford's new diesel V8 for 2007

"Ford will offer a diesel engine for its light-duty F-150 pickup, likely around 2008, according to a former Ford executive in Automotive News earlier this week. The engine will come from Land Rover's diesel-powered Range Rover in Europe. It's a 3.6-liter turbodiesel V-8 that makes 267 hp and 472 pounds-feet of torque in the Range Rover – and it helps the Rover get around 31 mpg on the highway."

(Philip says: Your fuel mileage and horsepower will be LESS because the EPA test sequence is being changed this year to reflect a more realistic drive sequence.)

3) You are not supposed to be driving all four wheels while on pavement ... which is where MPG tests are done. :wink:

4) But your Rover certainly has more rolling resistance. :idea:

Thanks for the advisory, Zen. :wink:

Refering to 100hp more than 48hp.(sd22..i thought they put out more than that??). not another 100 on top of my 95 n/a power!! sorry for the confusion..:wink:

Elsewhere on this forum, SD four cyl output in various trim has been detailed. Here's the "advertised" hp on my EPA engine sticker. :wink:

Just got back from a 131 mile (indicated) trip to San Fernando Valley and back. 3.0 gallons. Even if you adjust 3% for odometer optimism (127 mi), that's still 42.3 mpg. 60 mph travel speed, all highway. This is the best ever MPG and the truck will still peg the speedo when there's enough road. :D

Weather
79-83 degrees
17% relative humidity
Fresh NAPA 15w-40 All Fleet oil

I drove 455 miles in the past week in the '82 Wagon, ran it way down on the gauge. Filled it last night, just did the math: 32 MPG. That's got to be bogus, I'd never seen better than 29 in all the years . . .

Today, I drove another 160 miles. I should fill the tank again and recheck . . . nah.

Oh Dear!

A rash of high mileage reports.
Congrats guys.


Is your odometer accurate Al?

Philip: Is the truck in stock configuration, other than the OFV mod?

It used to be. I haven't checked it in years. I've got new tires on it recently but they are the same size.

Last tankful was 26, which is more like what I expect: 25-28 most of the time. I have just done more highway driving in the last week than usual, but again I've never seen better than 29 in this Wagon.

Perhaps you have a personal tailwind.

It's better than a personal storm cloud, as seen in older cartoons.



My speedo is dead accurate according to those radar speed-displaying signs that pop up in areas with a speeding problem, but my odo is about 5% off.

I had to erase the first thing I wrote. This is the replacement, isn't much, is it?
