I've used it once on my Silvia and it worked well. It is a good alternative if racing fuel is not easily accessable. A lot of local draggers here use some of the formulas listed since most are pinched for cash.
Someone posted this same link a while back which is how I found out about it. Perhaps you may get better input or long term use experiences from others.
