I am not sure, however i also think the shell vs chevron gas thing is mostly marketing.
Hmmmm, not sure but if I drove a VW diesel don't believe I'd pull into the lane where Kenwworths fuels up and vice versa. Fuel is all the same as far as I know except for down in Baja California, Mexico. They don't have ultra low sulphur and sells for equivalent of $2.50 per u.s.gallon.I have seen signs that say truck Diesel and Car Diesel. not sure the difference though
I saw this as well, I asked the folks behind the counter and they could tell me it is the same fuel, just a different size nozzel.I have seen signs that say truck Diesel and Car Diesel. not sure the difference though
You're right on the money, cap. Winter blend, or #1 diesel, is simply an addition of kerosene at the bulk terminal or, in rarer cases, actually at the station. Winter blend should not be confused with winterized #2 diesel which actually has some rather complex additives dumped in the tanker @ the terminals. These vary by chemical make up & amount in different geographical areas. While diesel fuel actually has more additives than gas (primarily due to the short comings of the ulsd formulation), they seem to be relatively standard & none brand specific. One thing that I found incredibly amazing is the fact that only 1 of our 34 refineries are able to meet all 5 quality standard categories. Our government seems to be setting lofty goals & then make allowances for the shortcomings of the nations antiquated refinery system!!You are getting good answers. As for the "blend" or winter fuel, there are additives, kerosene is one, that drops the gelling temperature point. Think some places call a mostly kerosene product [URL=http://www.dieselramforum.com/forum/usertag.php?do=list&action=hash&hash=1]#1 [/URL] diesel.
Normally you will not get as good a fuel mileage using a bit more kerosene in the fuel. When I lived in the frozen north I would add an anti-gel component to my fuel as a regular practice.
makes sense and keeps everyone in their proper places...I saw this as well, I asked the folks behind the counter and they could tell me it is the same fuel, just a different size nozzel.
