I have never run into your "plenty", tho' I'm sure "they're" out there somewhere. No spectators, I've met at any track care. I'm highly opinionated (can't you tell....) and, again, I could care less as long as they're ICEs.  |
To give a brief history, from 1996-2005 the IRL used pure methanol. In 2006, the IRL began to make the transition from methanol to ethanol, using a mixture of 90% methanol and 10% ethanol. This was primarily due to the late Paul Dana, who had brought the Ethanol Promotion and Information Council as sponsors, when he drove for Hemelgarn Racing, in 2005. When he moved to Rahal Letterman Racing, EPIC sponsorship went with him.
In 2007, the IRL switched to E100, advertising itself as the first competitive series to use renewable fuel. From 2012 season the Ethanol fuel blend was changed to E85, to match the mix used by road car engines.

NaBUru38 said: "In the early 1960s, cars would do just one pitstop, therefore they would carry many more gallons that the current 18."
To which I replied: "That's incorrect. For example in the 1963 Indy 500, race winner Parnelli Jones made 3 stops, on lap 62, lap 125 and lap 160."

I'm not too sure what you mean by that, this isn't a competition to see whether one discussion carries more weight than another.
