Good luck with those numbers. Exxon/Mobile get much of their diesel in New England from Irving. I talked to the delivery driver and he said no additives to distinguish between the two. Mobile sells Irving diesel, period. And I am sure that is the case with many stations.

In my research #2 diesel is much like gasolines in that the base fuel is the same across brands and it is the additive package that makes the difference. With that in mind I feel like I am getting as good of a product as if I had added my own extra fuel conditioner for about the same cost without the extra hassle.

YMMV

I run Southern States as well here at home. They have truck lanes. It runs well and I the turn over is good.

A Cetane rating above 50 begins to lose its percentage of effectiveness especially when comparing cost and effect. Ford recommends a Cetane number, not index, of 40.


Most states have adopted ASTM D975 as their diesel fuel standard with a minimum cetane number of 40.


BP (Amoco branded), 51
Chevron, 49 (51 with Techron D)
ConocoPhillips, 48
PetroCanada, 47-51
Shell, 46;
Sinclair, 46
Marathon 45
Exxon/Mobile, 43-46
BP, 40-42 (Powerblend 47)
HESS, 40-45
Husky, 40 (Max 41-45)
Sunoco, 40 (Sunoco Gold 45)
Holiday Stations, 40-43
Love's: 40
Pilot: 40
Valero: 40
Sheetz: 40
Flying J, 40
If I look at the sticker on the pump at my local Exxon/Mobile it has the number 40 on it? Come to think of it, I don't think I've ever gotten fuel from a pump at any filling station in CT that had a sticker with anything besides 40 on it

I would take those stickers with a grain of salt, they are likely a minimum rating rather than an exact rating of the particular fuel.

It would be nice to find an inexpensive cetane test kit. I spent the last 30 minutes looking for one and the only one I could find was $20,000.

40 CN is the minimum that most states have adopted IAW ASTM D975

I guess I'm lucky. I'm in the part of Texas that has the "good diesel" with a minimum cetane of 48.

I guess I'm also lucky to have plenty of places to get diesel and have never had to settle for a shady hole in the wall place that may/may not have dirty/watery diesel.

When I go on long trips and/or tow the 5th wheel I always carry at least two 5-gallon cans of diesel in case I get low on fuel and can't find a decent store. Learned that lesson the hard way. lol

Changed my fuel filters today for the first time (23k miles) and the frame filter was almost spotless. Only a few tiny particles I could see.

I wouldn't count on 48 Cetane minimum, there are rather a lot of "alternatives" listed:


Basic Requirements

The TxLED regulations apply to all diesel fuel sold or supplied as fuel for motor vehicles and non-road equipment operating in 110 central and eastern Texas counties.
TxLED must contain no more than 10 percent aromatic hydrocarbons by volume and must have a cetane number of 48 or greater, or else must use an approved alternative formulation or comply with the designated alternative limits.
Diesel producers may also use an approved alternative emission-reduction plan to comply with the TxLED regulations.

True. I wonder what those "alternatives" amount to....

I always run some sort of fuel treatment too just to be safe. Probably wasted money but it makes me feel better lol.

I'm "too you what" retentive and don't trust the fuel because how would you know? Once I learned that an additive package for lubrication is added to our crap "ULSD" fuel by the oil refineries, how would you know it's been added and therefore in there for the added lubrication that the fuel now lacks?


I've been using K-100 since the first fuel up after I bought my truck. Only have 14,500 miles with no problems, hopefully stays that way.


Good thread with good info...

IF putting an additive in does nothing but make you not worry about the fuel you put in - IMHO - It is worth it.

I'm still using and still a fan of Chevron here - Min. Cetane is 48. All the Chevrons by me only sell "Xtreme Diesel" - Chevron takes my supermarket fuel points so I typically pay $1 off per gal. when I get it. I just topped off the max. allowable amount of 25 gal at $1.89 per gal, rather than paying $2.89. I don't use additives with this brand.

One thing I noticed was that when I filled up at the "supermarket" pump because it was more convenient, didn't run additives, for the first time I got the "drive to clean" filter warning. Maybe it isn't related.... just seemed like an odd coincidence.

When I was on my 12k mile summer drive, I could immediately tell when I got low cetane fuel vs. high cetane fuel... Mileage dipped a little, noise up a little, regens more often. Which is why unless it was "premium diesel" or that Roadmaster XL stuff - I started routinely putting in additives. My Truck to me is like a high end sports car, you don't buy a sports car and put regular in it.

Just my .02.

I fuel up mainly at a station that advertises "Extreme Diesel". It's not a top tier fuel from the research I've attempted. It's #2 Bio Diesel with power service added and can contain 5-20% of bio Diesel. Don't know anything about Power Service Diesel Additive but I add 4oz of PM-22 to each tank. I'm one of those guys that fuels up when the tank is nearly dry because 200 miles between fuel stops is too short.

PM-22 costs me around .10 a gal additional to the cost of Diesel Fuel. Fuel prices in my part of the country are some of the cheapest at $2.35 gal, and is currently the highest I've paid for a gallon of Diesel since December of last year. Well worth the expense in my opinion.
