I would love to try this stuff.

My experience with the Saab is that the current model I have has lasted
nicely since 95.  I only have 40 K on it.  But that is partly because
when I got it in 1995, I still had my old 1981.  It had about 160k on
the odometer, maybe more.  The odometer died at 95000.

The support staff at the dealership here has only one Saab technician
at present.  Most Roanokers (and I fully intend to insult all Roanokers
here) are pretty much incapable of getting over their fear of working
on a computer driven car, even now, 15 and more years after they were
introduced.  WHile I don't usually like Roanoke naysayers, I agree with
them that the problem with Roanoke is Roanokers.  I like the cost of
living.  I do not like most of the weird attitudes that come from here.

Anyway the average Roanoker is scared to death of working on Saabs
because it is a computerized car.  They are also afraid of working on
electronics and they are afraid of the two years they have to devote to
get the Saab certificate of accomplishment.  This is amazing because
the mechanic salary for Saab dealerships is a lot.  There is a base
dollar amount and then a piece work rate they make.  If you get fast at
it, you can make double your salary maybe more on the piece work.

The service here is excellent, but there aren't many people who will
work on the car and they are currently looking for another mechanic.
They have even been advertising in national newspapers to get a
permanent second mechanic.

Their staff is nice.  Service has always treated me well. They have
told me when something was under warranty even when I didn't know.  You
have to follow their schedule of warranty checkups to stay in warranty
but that is ok.

They offer a shuttle service, so that you never have problems getting
home or to work

I am not at all familiar with what you are talking about, but I imagine
I will need to invest in a new car soon enough and this is interesting.

Well Charles, I don't have a Saab but I do have an '03 CTD in which I use
Stanadyne Performance additive.  It takes care of jelling and lubricity
issues.  I would rather use a known/tested additive in my Cummins.  I paid a
lot for it and want it to stay around for awhile.

Don't use gasoline. Gasoline removes the lubrication quality of the fuel
faster than it lowers the cloud-point. It's dangerous and damaging to your
injection pump. Too much gasoline blended in your fuel could cause
catastrophic engine failure.

Biodiesel is great for boosting the lubrication quality but it does cloud
and jell at a warmer temperature than #2 diesel fuel. That temperature is
dependent on the base stock that the biodiesel is made from. If the
biodiesel is made from canola (rapeseed) oil, the cloud-point /could/ be as
low as 14°F (-10°C). If tallow (animal fat) or palm oil is the base stock
the cloud point /could/ be as high as 45°F (7°C). That's a very large
variance in temperature, but that's for 100% biodiesel. You are only using
5% biodiesel. When mixed with #2 diesel fuel at 5%, the cloud point won't be
nearly that high. I wouldn't be surprised if you could go down to 0°F at
that concentration without clouding, but the only way to know for sure is to
test your fuel. If you are buying it commercially, get a sample in a clean
gas (or diesel) can. If it's already in your truck, the easiest way to get a
sample of your fuel is by using the water drain on the fuel filter. To
determine the cloud point of your fuel, put a sample in a jar and stick it
in the freezer. When the fuel turns cloudy check the temperature.  If you
expect the ambient temperature to drop below the cloud point of your fuel
you have to do something about it. I recommend blending kerosene (or #1
diesel fuel). It is very good at lowering the cloud point of diesel type
fuels without hindering the lubrication quality too much.
