That's *not* going to happen with a 3600 RPM air cooled diesel. I'll be surprised if it makes 1500 hours at half load, even if you change the oil every day.

I thought contemporary wisdom was that frequent, such as daily, oil
changes were a BAD thing with modern lubricating oils?

Modern oils with zinc and phosphorus additives require a certain
minimum amount of operating engine time to reach the lability point of
the organometal additives. The chelated zinc and phosophorus additives
are designed to be labile, so the ligand molecule will surrender its
metal load into a micro-void on the surface of a stressed engine part
(eg a bearing surface) when the ligand molecule has been stressed by a
heat/pressure event. The surrendered zinc, phosphorus or whatever
additive, by its deformation (because it's softer than the steel
bearing surface), is what protects the bearing surface.

Changing the oil too frequently prevents the additives doing what they
were designed to do. Of course, changing the oil frequently boosts oil
corporation profits. And if you're holding stock in Big Oil, that's
not a bad thing either.

Ah, Taxachussettes. I can understand why, now.

The rate reflects all those taxes paid by the company and all their
employees...It adds up quite fast.

What you say is true of a gasoline engine. But, in any diesel situation,
the big oil destroyer is carbon from all the blowby of the insanely
pressurized combustion caused by the 22:1 compression ratio and that
knocking explosion blowing it by even good rings.

The oil turns to carbon in a short time. Just pull the dipstick after an
hour of runtime and wipe it on your best shirt. It'll remind you to
change it OFTEN....not wait for amazing modern additives, now embedded in
lamp black, to coat the bearings. They can't even SEE the bearings!...

Yet another person who believes the myth. The Massachusetts tax burden
is lower than most states, about the same as SC. Also, our gasoline
taxes are lower than the national average, and the gas prices are lower.

It turns out that electric prices are particularly expensive, almost
double the national average, in all of the NE states.

I saw $2.96/gallon today. That low in Boston?

This is in Charleston, SC. Most stations are just over the $3 mark.

The discount stations in town, Hess and Getty, are $2.93 to $2.96

Out in the burbs its $3.09 to $3.19 and up

at $1500, approximately 1/4 the cost of the usual diesel
genset in this class, you can replace it 4 times to the break-even point,
spreading out your operating cost over many years, not at at the outset.

Here's my take on the numbers.

Let's assume a 1500 hour life which may be optimistic. That means you
are paying $1 per hour for equipment amortization which is more than
20 cents per kwh even if all your fuel is free. Fuel at current
prices would add another 20 or 30 cents.

Generating your own electricity is not cost effective if you can buy
it for 10 cents per kwh.


Let's take another shot at this one.
$1500 for 6kW of electrical power for 1500 hours
AND
6kW PLUS of heating over 1500 hrs
represents a combined heat and power capital cost of
8.3 cents per kWhr
Hence:
Generating your own power and heat can be cost-effective
if you buy power for 10cents/kW.hr

Then browsing the flyers, I saw a gasoline generator from Northern
Tool or Harbor Freight rated 5.8kW for $999 powered by a Subaru
Robin.... this might be an econimic possibility too.....

I wanted diesel because I have vegetable oil biofuel for it running out
my ears. All my cars and truck runs on vegoil we get free from Chinese
restaurants. I'm not going in the power biz with this genset. I live in
hurricane country. Diesel engines have a very long history of far
outlasting any gasoline engine made, of course.

They have diesel trains and ships for a reason...(c;

Since you brought the subject up =:-)

Do you have to heat the biofuel during cold spells?

Do you process the veg. oil or simply mix it with diesel?

Any problems with deposits building up in tanks.

I ask because I'm interested in using it in a sailboat where the fuel
may stay in the tanks for a considerable amount of time, depending on
the wind.
