I am on my 3rd fillup,and the last two was from two different Speedway stations,both have big truck islands and they go through lots of diesel,but this time I fueled with BP and right off the bat I noticed a difference it my truck,it was quieter and seemed to have more power,no kidding.
And the mid range clatter I was always hearing is gone,I have been only getting around 15 mpg mixed driving I got 468 miles on the last tank and the gauge showed about an 1/8 left,but I managed to get 32.968 gallons in the tank this time right to the top and it stayed there,so I know I got more in this time from the last time.
I picked my wife up from work tonight and she noticed it sounded different so I know it wasnt just me

But it is sure smooth and no more pinging or the mid range clatter.

 

What is the difference in ceteane rating between the two. I know where I get my fuel it is 42. Just down the block the fuel is about .15 cheaper but it is only 40. That may make a noticable diffrence.

 

I am so ignorant I did not know there was actually a cetane rating. I have filled up at "Al Cheepo" almost every fill up and have not taken notice. What are the ranges in cetane? Is higher better and what is the highest?

 

Most places don't advertise the cetane rating (most don't even know about it). It doesn't surprise me that you noticed your truck running differently. I can always tell when mine gets good fuel and when it doesn't. Runs smooth (for a 2nd gen ), more power, better mileage. Now, if only I could keep finding that good fuel and quit getting the cruddy watered down they are serving up here.

 

I never noticed it with the 2nd gen truck,or with the Powerstroke,but this one is a definate difference,I dont know the cetane rating for either station,but I am going to try and find out.

 

This may be a stupid question, but what in the heck is BP? There aren't any truckstop type stations in my area, so I am stuck buying from the run of the mill convenience stations at grocery stores, stand alone Texaco's, blah blah blah. Most of these places don't even know the difference between #1 and #2 Diesel, let alone Cetane ratings etc.

 

British Petrolium is a chain of stations around the US.

 

BP bought up Amoco a few years ago

 

British Petrolium in the US?? Is Tony Blair responsible for that?
Thanks, I'll keep my eye's peeled

 

at the BP near me , there is a sign on the Diesel pump"this is not an AMOCO fuel"
My point being is that BP Diesel is no better than Maw, and Paw. By me that is.

I allways goto HESS, a good AMERICAN owned company. And thier cetane rating is 42, for the same price as Amoco`s 40

 

I wish Texas would require stations to put the cetane rating up on the pump.

 

Ditto for CA... and about 20 other states I've been to that don't... c'mon Feds, this is a time for you to do something USEFUL!

 

I'll bet the fuel you bought at the BP station was either BP Supreme, or Amoco Premier diesel fuel, both have a minimum 50 cetane rating.

Since BP took over Amoco here in the midwest, they continue to market the premium diesel as "Amoco Premier", and at least locally, it isn't priced any higher than what other stations sell regular diesel for.

 

So, if Cetane isn't listed on the pump, how do I know.

Is there a website listing them???

 

http://www20.brinkster.com/beowulf9/tdi/PremDiesel/ is a site that lists where premium diesel fuel is sold. There are also 2 different premium fuels that BP/Amoco sells, Powerblend, which is minimum 47 cetane, and the Premier, which is minimum 50 cetane. Looks like in general, premium diesel fuel is considered anything greater than 45 cetane.
