Oil & Fuel NH specific fuel question

[ccap74]

Thank y'all. The "Power Service" does ring a bell. That is what my dealer was talking about. Why would I need to add that to my fuel?

Well:
For one thing to guard against the fuel gelling be it for use on or off road.

Will it harm an engine to run it on winter blend diesel in the summer time?

I have not had any problems yet. PS also adds to the fuel's lubricity as well as increases its cetane rating. Jay

***************************
I was reading in my BX service manual and it says to use winter blend diesel when it's colder than 14 degrees above zero.
Technically this means I could get by with summer fuel nearly the year round because we probably don't have 20 days through out an entire year that it is that cold.
Shoot we may not even get 10 days of it !

I hear you Lbrown! See'ins I could walk a half a mile, get on a boat, and float to your town in a day or so! Besides, most of my tractor work will be in warmer weather, certainly above 14 deg.

I'm tightwad enough to try to find an off-road diesel pump, as the on-road diesel fuel tax in Taxylvania - opps, Pennsylvania, is 62.5 cents/gal

Poking around I get real confused. As Lbrown says, in his neck of the woods they have one choice, be it home heating or whatever. Others here are saying home heating isn't as clean as off-road diesel. There's lubricity issues, as well, associated with ULSD, from what I'm reading. And then, I can't even find any "off-road diesel" in my little area near the extreme northern point of the mighty Ohio River. It may well be home heating #2 is all I've got here.

And where do I read up on this Power Service stuff? And do I add Sta-bil as well, or does PS fulfill that fuinction as well? Glory, the last thing I need is premature engine wear...

Another twist about "winter blend"...

Fuel venders used to mix kerosene with diesel to creat the winter blend.

Recent road fuel gov't specs call for ultra low sulphur diesel (don't know the ppm exactly). The problem for the last two seasons around here is no refineries make ultra low sulphur kero - so lately (as far as I know) there has been no winter blend available .

My pickup gelled twice last year. School busses locally have had frequent gelling problems. I found a source of undyed kero, and now mix it myself. You could use any offroad dyed kero or diesel in the tractor. It's over a thousand dollar fine if caught with dyed fuel in your over-the-road vehicle.

The old spec. straight #2 diesel gelled at about 20 degrees f.
Winter blend mix was good down close to 0.
Beyond that an addative was needed.

ULSD gells just below freezing - about 30
So, more addatives are needed. Or mix the kero yourself - I add about 25%

The new ulsd is also less slick (lubricity) so most use addatives all year for better injector pump life.

1*Must be summer blend but 30 degrees sounds high even for summer blend.
Winter blend should be good for way lower than 30.
I can run summer blend down to 14 degrees so it's kunda hard for me to fathom winter blend only being good down to 30 degrees.
The trouble with doing this is you are diluting a fuel that's already been diluted if it's winter blend.
2*How do you know they aren't using the kero they have?

I knew ahead of time that I would have summer diesel still in my tractor come winter time. So I read around, and someone on one of the diesel truck sites did a study of the different additives-- I'm sure somewhere on TBN there is a link.

I chose Optilube XPD since it is lubricity enhancing and anti-gelling and rated almost as good as biodiesel for lubricity (BD isn't so good for gelling!). Fairly expensive, but avoiding having to wait for warm weather to move snow would be worth the cost. Some of the other popular 'brands' did not rate so well, I was surprised, and some things people use for anti-gelling do a job on lubricity. Late model injectors don't like 'dry' fuel, and I don't like hefty repair bills.

Thanks fellas'. Its a longer drive to get the "red" fuel, so I won't have to worry about making the longer trip and just stick with the "taxed" stuff.
