Being a new owner, but not new to construction equipment, I have a question about diesel fuel. I have only filled up once (citco) where the fuel smelled "normal" and was green. At pilot and sunoco, it looks clear and literally smells crappy--like sewage!! What gives? The red stuff at the job always smeels "good" like I think diesel should. The truck does not run any different with fuel from the three places mentioned above. I only got 2,500 miles and am just trying to find a "regular" fill up spot--without using the red stuff at the job--course it is much cheaper! LOL! I have read that BP/Amoco is the good stuff, but it is really out of the way. Is my sniffer bad, or has anyone else noticed this bad smelling fuel?
