The GOV auctions have lots of good stuff but, I find the best deals at property room;

Well, I committed to buying that tractor that I was looking at. It's a Farmall. I'm going to have to buy a straw hat and learn to "chew"

I wish there were home made/makable fuel stabilizers for diesel, and, gas...
the prices are dropping, but, for how long?
it'd be nice to be able to store some for a year or better.......

anyone got any info on this?

that's why I like propane for generators, it never goes old.....

They make a stabilizer for petrol that works.
I don't know about diesel, but I would expect it to be far more stable.

Some types of gasoline are far more stable too.
Ethanol isn't helping anything.

and, diesel stabilizer is good, and cheap,
but, for gasoline, it's really expensive.....
I was hoping for a formula.......

I use Stanadyne for diesel.......

I found Sta-bil for $15 for 32 ounces, enough for 80 gallons.
Doesn't sound too bad if it works.
I found gallons for about $44, $53 with shipping to me.

SAE should have some technical papers on fuel stabilizers.


My volvo is gas, in this model the preferred engine.
The best way to raise compression is with the proper pistons, but you can always build up carbon on the heads.
The engine is 9.5 to 1 lowered from the european settings.
I'll probably change to a better cam too.

I recently found out that the ignition system I have is independent of the bosch fuel injection and identical to a chrysler, so cheaper to replace.
If I can satisfy one cue to the fuel injection, I can ditch the ignition and install my big jacobs system and add a manual advance setting on the dash.
This will also allow me to double the plug gap.

The ultimate tweak will be ditching the fuel injection control for a newer mappable one.
There are plenty available and some add ons for a few hundred now.

This is an option for all older cars now.

I got the industrial stanadyne for 24 bucks for 2,000 gallons treatment........
still using it........got it several years ago from a farm supply online.
only for diesel, though.........

I"ll have to try more research......find a formula for fuel stabilizers.......

are volvos fuel injected?
could you shave the head to raise the compression?

Mass air by 1986.
Probably the same system as the Mercs.

You can shave the heads, but it's never a good idea and the improvement is limited.
I'd rather upgrade the pistons and have better squish control and put in better balanced pistons at the same time.
I could go lighter or use forged for more strength, and I could move up to gapless rings if I chose, coated pistons, etc.
Since the heads may go forever without needing work, it seems like a bad idea to tamper.
Head strength and resistance to warping is such a crucial thing, I hate to risk it and if you have any issues, you have no metal to remove left.

Curiously my rail type on my 1980 seemed to get better mileage and better acceleration.
This seems to be common and I can understand the power but the rest is a bit baffling.

Absolutely.
And the efficiency goes up with that.
It's a bargain.

If you have manual control, you can set for regular and dial it up and down at will.
Best efficiency is with the most compression you can get by with though.

My 408 is 12.5 to 1 and gets 25 mpg with 500 hp/500 lbs.
I can get by with regular if I don't push it hard, but the mileage goes down.
Unless there is an unusual jump on the premium, it's cheaper if you exploit the power.
You can buy race fuel and mix with regular too.

As gas goes higher, the difference is smaller by percentage too.

Homemade fuel stabilizer for gasoline.

No warranty make at your own risk etc etc.

Ingredients are as follows

Heavy Aromatic Naptha AKA Solvent Naptha
92 percent

Isopropyl Alcohol
4 percent

Napthalene
4 percent

For extreme cold change to 88 percent solvent naptha, 8 percent iso pro alcohol, and keep the napthalene at 4 percent.

10 ounces will treat 25 gallons or so for about a year.

FYI The Stabil MSDS I have lists the petroleum distillates at 95 percent and 5 percent "additives".

Edited to add:

I know very little about chemistry but as I understand it what fucks up gas is that the lighter (molecules?) evaporate and the heavier stuff thats the moral majority of the fuel winds up gettin gummy. This recipie will "revamp" the fuel for awhile (12 months) at which point you should use it, don't think you can keep adding sta-bil forever as the formula will get all screwy or some shit.

how would you manually control compression?

Thanks for that.

is the isopropyl alcohol 190 proof? I'd assume so, and, would wonder where to find it so strong....seems the best I've seen is 140 in some drug stores......
Where to get napthalene.......?

I wonder what the 'additives' are? maybe colorant and perfume to make it smell nice, or, mask the smell so people won't guess what it's made from?

hhhmmm, I'll try that..

I was talking about ignition control, although they use variable compression on the new state of the art engines, usually by varying a supercharger.
There is one that alters the combustion chamber.
It's the same idea.
I can't find the jacobs dual system anymore- one for load and one without.

You can buy lead, but it's very toxic and only a false octane, a knock reducer.

408= 408 ci ford small block.

oh, ok......I get the ignition adjustment thing......a fancy one of what I made so long ago, when I drove cars with distributors and spark plugs.......

wow, that must be interesting to vary a supercharger for compression........and, or altering the combustion chamber, how would they do that?
yeah, tet/lead is quite toxic, but, IMHO, the best octane increaser....

are you sure it's false octane? I thought that was a measure of burn rate/volatility, and, therefore, knock/ping resistance........higher allowing for less pre-ignition due to either increased compression or advanced timing .

dang, that hurt my brain.......

YGMIR, octane is just a measurement of 8 atom ring molecules.... 8 atoms. Cetane is the measurement for diesel,,,10 atom ring molecules. Octane is a general reference to burning speed. The more 8 atom rings, the slower the burning speed. Knock is what happens when the flame propagation speed goes up too high. The newer engines have a knock sensor. You can connect up a knock sensor and crank up the advance. Not quite that simple but it acts to guard against knock. There are other things that will slow down the flame propagation speed
. Alcohol works,,, so does water. A good water injection system is a cheap way to slow down the burn.
When the long chain molecules break up, they make gunk. I think Sta-bil helps to preserve the long chains from breaking. Diesel isn't near as volatile. it doesn't degrade near as easily. I just started an old Detroit with 12 Y.O. fuel.... No smoke.
Some of the newer engines have a variable control on the turbo waste gate. They have a low cranking compression but a high effective compression. The dual-fuel engines generally had a third valve that opened to a small chamber. They operate on gas with the valve open and on diesel with the valve closed. Lotsa strange stuff.
I don't post things because I believe that they are the absolute truth. I post them because I believe that they should be considered.

In case anyone didn't already know.. gas line antifreeze is just isoprop alcohol with "additives". Often these additives are indeed a coloring like Red #5 or some shit and possibly a perfume agent to throw off the curious. Your paying for the container in many cases, in some cases a brand name does make a HUGE difference when it come to actual formulas that are unique to that brand.

When I lived up north I used regular ol iso alcohol from the supermarket to sort the gas line. You are adding so little that if its not "perfect" it will still do the deed. I remember someone had added a quart of oil to the gas tank after bring told they needed a quart, lots of smoke but nothing blew up.

Lead controls burn but adds no energy.
There are much better approaches.
Lead was used primarily due to cheapness and valve lubrication.
It does affect octane but without adding any potential power.
There are some much better mixes out there.
There are a few additives left with lead in them.
Reviews are mixed.

Variable Compression

http://www.saabnet.com/tsn/press/000318.html
Image
The Saab Variable Compression (SVC) engine is comprised of a cylinder head with integrated cylinders, which is known as the monohead, and a lower portion consisting of the engine block, crankshaft and pistons. The compression ratio is varied by adjusting the slope of the upper part of the engine in relation to the lower part by up to four degrees. This alters the volume of the combustion chamber and changes the compression ratio.

The energy in the fuel is better utilized when the compression ratio is as high as possible. However, if the compression ratio is too high, the fuel will pre-ignite and cause "knocking," which could damage the engine. Due to its variable compression ratio, the SVC engine can be run at the optimum compression ratio of 14:1 at low load in order to maximize the use of the energy in the fuel. The compression ratio can then be lowered to 8:1 at high load to enable the engine performance to be increased by supercharging without causing engine "knock."

The SVC engine concept reduces fuel consumption by up to 30 percent when compared to a larger conventional naturally aspirated engine of similar power output. It also provides the tremendous power output of 140 Ib.-ft. of torque and 150 horsepower per liter of engine displacement.

Engine displacement 1.598 liter
Number of cylinders 5
Cylinder bore 68 mm
Piston stroke 88 mm
Compression ratio 8:1 to 14:1, depending on engine load
Max. compressor boost pressure 2.8 bar (40 psi)
Max. monohead tilt angle 4 degrees
Maximum torque 224 Ib.-ft.
Maximum horsepower 225 hp

The hungry people with no jobs or food coming to take what they can from you any way they can.



Facts & Figures
The reason why we provide food to the community is not simply a moral one. Scientific evidence suggests that hungry children are less likely to become productive citizens. A child who is unequipped to learn because of hunger and poverty is more likely to be poor as an adult. As such, the existence of childhood hunger in the United States threatens future American prosperity.


295,000 children are living in poverty in South Florida.

Miami ranks 3rd among large cities in the U.S. with 35% of the population living in poverty.

42% of the children in the City of Miami live in homes with incomes below the poverty level.

59.8% of Miami-Dade County public school children were eligible for free or reduced cost lunches.

Between 2000 and 2001, poverty rose to 11.7% of the population, or 32.9 million people, up from 11.3% and 31.6 million.

The number of food insecure households with children has also risen since 2000 by 10,000 to 6.18 million.

During the 2003 fiscal year, 16.4 million low-income children received free or reduced-price meals through the National School Lunch Program. Unfortunately, just over two million of these same income-eligible children participated in the Summer Food Service Program that same year.

Poor children are at risk of nutrient deficiencies that can lead to serious health problems, including impaired cognitive development, growth failure, physical weakness, anemia, and stunting. Several of these problems can lead to irreparable damage to young children.

In the last decade, hunger-relief agencies have found that the greatest increase in hungry Americans has been among the working poor. Despite the strong economy and their own hard work, they cannot always make ends meet. And increasingly, they are turning to charities and non-for-profit programs for hunger relief.


Things are only getting worse here in FL, record turnouts for food handouts and occasional violence over food.

http://www.dailybread.org/

I try to drop off cans once a month. This month I can't swing it, pasta and rice for us all month :)

PS: Don't expect the millions of jobless to drop off the face of the earth or to leave the country. Obama is powerless to bring the work back, he cannot force people to stop buying from China or the Corp ppl to keep their manufacturing here. Vise Grips is gone now.. whose next? The exodus of jobs overseas continues unchecked since Clinton opened the floodgates fully. Since Obama is also a Dem I expect jobs losses will increase in record numbers.

Your country is STILL in debt from the Depression and is getting deeper in debt daily.
