  1. The differences are easily explained by the differences in the blending. Fuel is never made with 95, 97 or 98 RON exactly, but is different components which are blended ( using an actual engine in the plant) to make a fuel that is around ( plus or minus a small amount, depending on the day and just how the output is at the time) the right figure. Your BP ULP and the ADSA ULP might actually have come from the same tank in the same tanker during delivery, but depending on what the actual RON of the rest of the tank ( and whether there was more or less water in the fuel) was easily explains the differences. The 97 and 98 RON fuels are exactly the same, blend wise, just a different additive pack ( or coloured dye in most cases to tell them apart in the tank) added at the refinery. I doubt they are all different refineries, likely all came from the same refinery in the vicinity, and just were delivered to the different garages in a tanker, either branded for the garage or plain white, depending on who was paying for the delivery. BP green tanker if BP was paying, white if the refinery was paying. Here all the same fuel, all delivered in the same tanker from garage to garage, so the BP tanker is a common sight at all garages, even non BP branded ones.

  2. I worked with a guy who did aircraft tyres. His test station for the first inflation was a concrete room with 3 foot thick walls, with a blast proof steel door, and a roof designed to blow off in case something went wrong. Nicely far away from anything else, and he made sure that he never had to call in to get the roof replaced because of a fault he did. Those old aircraft tyres are sought after by farmers for agricultural trailers, simply because they are so tough that even driving through heavy thorn bushes will not puncture them, your tractor might need a patch on the big drive wheels, but the steering axle with those on will never puncture, though they are not street legal at all. But for the farm tractor perfect, lasting for many years.

  3. +EazyDuz18 Could also have been the winterised fuel with ethanol and methanol, added to the original summer fuel mix it likely had. A good place to look for the hesitation would be to clean the inlet system, and the PCV as well, to get the carbon out. Classic flat spot of a dirty inlet system and blocked PCV piping and valves.

  4. With the modern misfuel they put DEF into the fuel system, which will destroy it totally. If you find it, and have not turned the ignition on, then all you need is a drain of the tank, and a new fuel pump, filters and a flush of the fuel lines. If you started it you need to replace injectors, fuel rails and fuel lines, along with high pressure fuel pump as well, because they will be destroyed.
