40 + mpg out of a mid size truck?

[alohaspirit]

good points.
im for the use of wvo in any shape or form. im just against it being dumped. PERIOD.


i wish there was a better way. ive talked to many fast food owners and they noted that a lot the oil made its way into the landfill. (even while illegal to do so) and another thing to note is the island of oahu doesnt have that many septic systems making your option a little less viable.

we have a large biodiesel company now, but people are still dumping waste oil.
were running out of space for landfills or pretty soon all you will see is:
HOTEL --- LANDFILL --- CROWDED BEACH --- LANDFILL --- HOTEL --- LANDFILL ---

on a side note, local temperature is rarely under 70F
so WVO as a fuel is more feasible here than a colder place such as PA.


Each year in the United States alone, 3 to 4 billion gallons of Waste Vegetable Oil (WVO) are being dumped into landfills, added to pet food and cosmetics as well as filtered and sold as "cooking oil" to people in third world countries. This same waste oil can be used to cleanly power our vehicles. After reheating the oil numerous times, restaurants must pay someone between $1 and $2 a gallon to dispose of it. WVO makes economic sense in today's high priced, petroleum monopolized, fuel market.

Walt Bacharowski, president of Silicon Valley Biodiesel, points out that in the San Jose area alone, some 8000 tons of trap-grease per year goes into local landfills. If all of that waste oil were converted to biodiesel, it would amount to about 1.4 million gallons of biodiesel from the San Jose area alone.

We can agree, I hope, that either straight WVO and BD are better than petrol, and that better mileage is a plus no matter the fuel source?
We're kinda taking over the thread, when there is a forum section specifically for this argument.

In case anyone thinks that glycerine gets burned in the engine, look up the combustion temperature for Glycerine... it's about 1,800*F, or ~1,000*C, and needs to be sustained there. Guess what temps your engine doesn't reach and sustain?

acroline is the only toxic I can think of and that is only if your motor isn't getting enough air and running cold, the others are considered particulate and more benign than breathing Dino diesel particulates.

Glycerin burning technology from AlterHeat

Anyway diesels do internally get very very hot along the flamefront but for brief periods of time (although longer than a gasser) I cannot think of anytime a diesel is sitting under 300c in the chamber during burn except during warmup

Also acroline lein whatever is produced by burning wood, it can also be found in small quanitites in normal diesel exhaust during warmup, alcohol blends of gasoline and many other combustables when the temperature isn't high enough.

So I am uncertain if it is any more dangerous than anything else and it biodegrades in water.

Just don't sit by the tailpipe and you should be OK as the stuff tends to break down.

meanwhile, back in the big trucks with big mpg's thread......:-)

I have seen this MPG one time before,but at a steady 45-mph for 200 miles.
I think 40 is doable,but for the T-100,I think it will require the trailer.

You forgot one tiny fact. Cloudcroft is at about 8000 ft MSL. Artesia is about 3500 ft.

Sorry to get off subject which seems to be WVO vs biodesiel.

5,122 foot drop.

OK what is fe in the other direction?

Let's see, that's almost a mile, so subtract 1 mpg right?

With the CRX,I continued on to Denton (around 565 miles trip total) and pulled 75.8 mpg.The uphill 565 miles was 57-mpg.
With respect to the T-100,I was curious to see how the downhill leg would impact mpg.
If R-R or aero were reduced to yield the same average "load" as assisted by gravity,one might presume that in level driving,the truck could return that kind of mpg at that velocity.
Since Alohaspirit is going for 40-mpg in a mid-size truck,I thought the data might be insightful.

its not my thread, but ill take 40 mpg in any car, van or truck

Yes that could be mathed out but I'm not going to try it!
