This begs the question: is there ANY truth in the nugget about good diesel vs poor?
Ford recommends BP and I "think" Mobil diesel. Several mechanics have told me this over the years too, and to avoid Woolworths-Caltex/Coles-Shell/Costco/United (and very definitely Tesco in the UK
)...
Is there even a tiny bit of truth in that? My Ford runs beautifully on BP Premium diesel, but put even a 1/4 of a tank of Caltex top up, and it runs like poop. Within as little as 20km! So, I run the car almost exclusively BP (as per Fords advice). My fuel economy on the highway is 2.3L/100 and about 6L/100 city/town on BP, and almost DOUBLE that if using Caltex (Shell is a little better than Caltex)
Are formulations per company drastically different now that all diesel is a concoction of 51 herbs and spices instead of actual diesel? Last time I changed the diesel filter (after using Caltex for most of a year) it was putrid black and water coagulent present. Recent filter change after nearly exclusively BP and I reckon I could have put that old filter right back in, and the filter bowl was clear.
