Post subject:  Premium Diesel Q's

I've seen posts regarding Premium Diesel and was wondering if the pumps are marked "Premium". I've been to Shell, Mobil, and Chevron stations in the Phoenix area and have yet to see a pump that is marked with Premium Diesel.

The word premium is not really a good source for defining quality of diesel fuel. To be able to call a fuel premium there are 5 standards for which the seller of the fuel only has meet two. One is minum cetane value of 42 (if I remember correctly) another is for minium clean standard. Most fuel by those old standards in US then can be called premium fuel. If you do a Google search for the premium diesel fuel maybe you can find the actual standard and post it here. I haven't looked at it in at least 3 or 4 years.

Premium diesel????? I think the only way to get premium diesel in this country is to import it from Europe!!

There are no markings of any kind on the diesel pumps here in Indiana. No centane, and no indication of premium of standard diesel. Sometimes I see a co-op advertising premium diesel on their sign, but it's not on the pump.

I went to a sporting goods store and bought a little 21oz aluminum fuel bottle made my MSR to hold my PowerService. This way, I create my own version of premium when I fill up as I dump about a third of that bottle in each tank.

Yes unless you know for sure the Power Service is a must. The fuel bottle is one way to do it, but afer years of trying everything under the sun I have finally hit what has worked best for me. The plastic 12 oz soda pop bottles are the cheapest and best thing for hauling the PS in, they don't leak, free, and can be thrown away on trip no smelly emptys with PS on outside stinking up the Jeep. Remember if you spill just a couple of oz of the PS it wil stink up the vehicle something awful for days if not weeks.

Thats for sure! I keep the bottle in a one gallon zip-lock bag with a few paper towels so I can clean it up before I seal it up if necessary.

Take a small funnel and collect some soda bottles (rince before using) and fill them with PS and stow them on shelf and/or throw them in the storage net in the back. Just a hint from a long time user and traveler with diesels and Power Service. These 12 oz soda bottle hold just the right amount for each fill up, and then tossed.

I use the Stanadyne one shot bottles. About 3-4 bucks a piece, one to a tank. I store about 6 or so under the hood behind the battery, never had a problem with them leaking or even getting hot.

Hey alljeep, the Co-op in Noblesville has 51 cetane B2. They call it "Premium Diesel R"..

What's the price on the 51 cetane. I'm paying 2.91 for B99 from Western States Petroleum in Phoenix, no idea what the cetane is.

B99 will be 50 to 55 Cetane, depending on what is the bio base stock.

They are using Soy based bio. The price is actually closer to 4.00 a gallon but they recognize all of the tax incentives which drops the price down to 2.91.

Do they sell fuel in bulk? like 55 gal. drums etc.... or anyone for that matter, there isnt any Bio-D within a 100+ miles of me that I know of.

Yes they do. Go to westernstatespetroleum.com/biodiesel.htm

Biodiesel is a great way to boost the cetane of US grade diesel fuel. Seems like a little B100 is all it takes to settle things down, at least in my CRD. Does anyone have a chart of biodiesel percentage vs. cetane boost?

Depends somewhat on the feestock used to make the biodiesel. But lets say you are using a feed stack that has 50 cetane and you are mixing it 50/50 with 42 cetane fuel, I would assume you would end up with 46 cetane fuel. A Google search should be able to help us find out for sure.

What most here notice when using almost any mix B2 to B100 is how the engine noise or rattle goes away, what causes that is the lubrication effect of biodiesel. This cleaning and lubrication effect is not increased beyond about 5% to 10%, there is an exact amount point but I'm too lazy to look it up.

Love this headache first thing in the am, must be my allergies.

Judging from my CRD experience, just don't think it is a simple average of the two fuels. There is something about the blending of these two different fuels that changes the combustion charactoristics. B15 to B20 seems to burn as clean, strong and quiet in this unit. It would be nice to have some Euro grade ULSD to try as a comparison. Last week while in England several CRD's drove past, didn't notice any of the diesel rattle I hear from mine running on straight petrol diesel. The TDI's (which are everywhere) sound very quiet.

I guess it depends on the cetane rating and what lube additive used by the fuel supplier. Most fuel in Europe is 50 to 60 cetane and that will also lower that rattle effect as will the lube additive be it a bio additive or some chemical lube additive.

I was in western europe last month and also noticed all the diesels. About 50% of all vehicles seemed to be diesel and virtually all the taxis were jetta/passat tdi (except for a few mercedes). Oddly enough, the city streets did not have a strong "diesel" odor. Maybe it was the ULSD fuel?
