It seems that the majority of the problems occur when buying Sunoco products off of the trucks at NHRA National and Divisional Events.. Sunoco products have been proven to be very inconsistent, and even if the lower fuels test OK, are you getting the right performance out of your set-up, or are you blaming the track, or the weather??.. and actually, it's been proven that Sunoco shelf life is non-existent.. so, just cause your car runs when you put it in, doesn't meaning that your car is actually running..
I actually couldn't believe that on the Sunoco chart, VP C-14+ crossed over to Sunoco SR-18, but to use the SR-18, I found that I had to make a timing and jet change, and couldn't get the car to come close to a decent idle.. THANK GOD that VP showed up that day.. took the rest of the 5 gallons to fuel check, and it failed for SR-18.. but I was told that I could use it.. WTF???... but don't listen to me, back to back it your self..
SOOOOO, I got a chance to back to back the fuels, at a good track (Maple Grove), with good weather (SPRING TIME), and the SR-18 got poured into the motorhome... IMAGINE THAT!!!
I watched dyno pulls on a current Pro Stock motor, back to backing fuels.. on the best tune-up, SR-18 was down 30hp... wonder what you're down in your combo... OR, if you're using Sunoco, how much better would you be with VP RACE FUELS???
NUFF SAID!!!

I've been buying Sunoco off the truck and in pails for the past 4 years with zero issues with fuel check, consistency or performance. I've also have had zero issues with storing fuel from October to April. I've also lucked into winning a few races and setting a record or two. To speak of Sunoco as if its an inferior product is just being naive.
Last time I checked this was the Stock/Super Stock section of the forum where fuels like C14+ and SR18 most likely are not primarily used so I cant speak to these products....I can tell you we've run VP C11, C12, C25, Sunoco Blue, Purple, Maximal and Surge and they all perform well and pass tech if handled appropriately. So to your answer your last question, for most stock eliminator engines the answer is not one bit.
