With gas I never noticed a difference either, I think its a placibo affect. People think Mobil or Shell is better than say Stop & Shop. But modern cars will run on any 87 piss you feed them. Unless you have high compression and really need that 93 to be 93 I think its all in peoples heads.

With both diesel and gas I buy whatever is cheapist, they all come down the same pipe.

All of what you said makes sense up until you started talking aboutu gas, I believe the plecebo effect only comes into play for the octane portion or the gas equation, if the car has a lower compression engine that does not require Niger octane to control preignition but you use it any way because it makes you feel all warm and fuzzy inside then you are wasting your money.
But as a Mercedes technician I have seen first hand the benefits of quality gas, a good one that will always come to mind is one of my customers owned an Arco station and he only used Argo gas. Well one day his car was towed in with a no start condition, turned out he had so much carbon build up on the valves they were all partially stuck open and would not allow compression to build. I know it is in the additives (techron) but you do not see this with chevron or any of the large companies.

CR from Texas,

I've always used the Redline Diesel Fuel Catylst and Startron...Long before the
LSD and ULSD.(North American Diesel fuels have been Low Cetane ever since
the Refiners started "getting away with it" after WWII/Korea.)During WWII the
Diesel fuels refined in USA were second to none.
The Redline just happens to have a lubricity additive...But not enough to
overcome ULSD's lack of lubricity.Hence the TC W Synthetic.

Thanks CI,
It's been a long time since I bought any 2 cycle oil (lets see, 1950's Allstate moped) but I'll start - seems like cheap insurance against IP issues. Looks like I'll also start looking for some viton tubing for those return lines.

after filling up in juarez, mexico I got 31.4 mpg in my 300td, driving 75-80 with the ac on. all highway, ok but that pretty much told me what quality diesel you get in the states...

could have been 33.4, it was a while back. all I know is that it was 4 mpg more than with "usa diesel", i tested it on a road trip back then.
