Talk:Cetane number

Anybody know what the story is on finding out the cetane number of fuel at the pump? I see octane rating at every gasoline pump these days, but I've never seen a cetane rating. Are they required to display octane, but not cetane? Or is there just no demand for it?

I'm not sure, but maybe they believe owners of diesel-fueled cars don't consider the cetane number (or don't care/know about) while purchasing their fuel. Most people consider diesel just for its fuel economy.
It may also change with seasonal changes to composition. Rmhermen 00:50, 4 March 2006 (UTC)

The CFR engine is slowly being replaced by newer test instruments such as the Ignition Quality Tester. (www.aet.ca)
