ULSD, vs Regular, Additives????????????
- How careful do I have to be about where I go for diesel fuel? Are some stations - Shell, BP, Sunoco, etc. better than others?
- Can I mix ULSD with Regular, or if I run with ULSD, do I stick with ULSD?
- How necessary are additives - ULSD vs Regular, summer vs winter? I live in Michigan and the winters are always below freezing and can get down to 0 F.
- As this will be a new vehicle, do I need to do anything special with the fuel during break in?
1. Go with a major brand - stay away from low volume dealers
2. All you can buy in Michigan is ULSD as far as I know. But every pump is to have a tag on it showing what fuel is being pumped during this phase in of ULSD fuel. If your truck requires ULSD then look for the tag stating it is approved for engines made in 2007+ and it will state fuel is 15ppm sulfur or less.
3. Fuel here is automatically winterized from October thru April.
4. Nothing required
As soon as you get your new wheels. Read the diesel suppliment manual from front to back. Especially the break in area. After 1000-1500 miles change the oil. After that follow the severe duty reccommendations. This will keep your motor and you happy.
One thing on fuel.... If you can find a station which has a Premium diesel use that. The 6.0 likes premium vs regualar diesel fuel. some truck stops have it. Like Don's truckstop in Diamondale (Lansing rd exit) on 96
Enjoy and welcome to the diesel club....

By the time you get your truck all that will be available will be ULSD. It will work just fine without adding anything ever.
I have never used any additives in my truck in the last 368,000 miles & don't intend to start now.
I agree on reading the manual but not on adopting the sever duty maint. schedule.
Actually I stretch my oil changes out from what Ford recommends.
Nope... No break in needed. Just enjoy and come back with any more questions you have.
P.S. I buy my fuel at the cheapest place I can find, large or small. I do like places where I can pay at the pump better though.

Check out the Stanadyne products, they are the only OEM approved additives available. For winter MI use get the Performance Formula, cetane improver, winter gel protection, cleaner and lubricity all in one bottle. Summer use the Performance JR, same featues but no gel protection!! Call us if you have any questions on it.

- The article referenced above clearly states the lubricity of ULSD is less than previous fuels. Does that then mean that additives should be added to increase the lubricity to previous levels?
- One station I observed sold "bio-diesel". Is this something to consider using or stay away from?
- I compared prices at several stations. Diesel was anywhere from 32 cents to 57 cents more than their regular grade of gasoline. Is this large of a spread reasonable, or is there something better about the more expensive ones?

It might be a little "less" but it is still more then enough to run new & old trucks without adding anything.
"One station I observed sold "bio-diesel". Is this something to consider using or stay away from?"
Bio-diesel has been tested & proven to be safe for use in our trucks (or any other diesel engine) . If the price is right ...go for it.
"I compared prices at several stations. Diesel was anywhere from 32 cents to 57 cents more than their regular grade of gasoline. Is this large of a spread reasonable, or is there something better about the more expensive ones?"
No... This is just plain & simple GREED. If you check futher, You'll notice as much as 20 or 30 cents difference for fuel in the same city at the same brand station.
Like I said, I use whatever is cheapest & haven't had ANY problems in over 368,000 miles.

As mentioned either here or on the Diesel-Stop forum, it's not the reduction in sulfur that's the problem. It's what goes out with the sulfur that causes the reduction in lubricity - for which Chevron and other refiners have to make formulation adjustments.
