MPG with different diesel fuel brands
A little bit of interesting data some may like to know. A little back story..... Due to farm tax expenses and other side businesses I have had over the years, I recorded my full ups for my truck. ...

Related maybe, but both this truck and my 7.3 have always got noticeably less mileage on US purchased fuel vs Canadian fuel .
That is across any state and a couple of provinces,I was told canadian cetane minimums are higher?
44 vs 40 ?
I dont know but I buy both sides of the border since 2001 and its been consistent and noticeable but very slight.
it is possible the canadian diesel must be higher Cetane. Most of european countries have much higher Cetane requirements than the U.S. as well. Primarily because so many of the vehicles are small displacement high RPM diesels which require a higher Cetane rating to complete the fuel burn at the rpm they run. In the U.S. Cetane ratings initially were set based on what a industrial diesel (class 8 truck etc.) required and those being very low rpm engines could run on a much lower Cetane rating.
As a result U.S. "high rpm" diesels are designed to run on the lower Cetane rating, which does restrict the power that could be attained with a higher minimum Cetane rating.
interesting
thanks
