I’m not sure why everyone is surprised the cost of fuel has gone up a few hundred over the past 10 years.
If I remember correctly, when NHRA banned Schumacher nitro (2008), the price of Sunoco or VP jumped from $900 a barrel for 55 gallons to $1200 for 50-52 gallons and is now in the $1350-1450 range. It’s damned expensive.
However, over the same time period, the VP C12 racing fuel I used to run has jumped roughly 100% from $8.00/gal to over $16.00/gal.
It probably doesn’t cost that much more to produce the good, in fact I’m sure the process is more refined (no pun intended).
