Done.

 

Go ahead and throw your money away buying cheap low octane gas. Just be sure to set some aside to repair the motor later on.

 

So the answer is.. No, use 91+ Octane gas. Period.

 

So what if I run regular gas but ask it really nicely to burn at a higher temp?

 

found a place in town today, run by a little old man, that sells ethanol free 93

 

I try to stick to the major name brands like Shell super premium 93 octane or Sunoco 93 octane. Even at 30 cent a gallon more than 87 octane it does not amont to all that much in a tankful. I'd ratrher put in less 93 octane than more 87 octane for the same cash price. Suit yourself dude.

 

how about the opposite question. is there such a thing as too super of super unleaded? im remembering the clark station (do any of those still exist) in winthrop harbor illinois that sold i think 104 octane "racing fuel" 15 years ago it was 2 bucks a gallon. id hate to see what it is now if that place still sells it. and i wonder if it would work better than the type r sticker im planning on putting on my fender lol

 

93 octane tastes better than 87 anyway!

umm, no "Gas Huffer" smiley?

 

I have from new a 93 range rover, a 96 discovery and a 2010 range rover... I only use premium fuel... I was told by my service tech that this will help with the longevity of my vehicles..... so far so good... I still have all three vehicles ( 93 RR with 198,000 miles, 96 Dico with 68, 823 miles and 2010 RR with 23,000 miles... Frequent oil changes, and Good fuel are a MUST with these vehicles... I hear horror stories every day from people who skimp on maintence and pay for it later... just don't do it...

 

I remember in 1998 I was driving through Tennessee in my 1972 Dodge Dart, and I came upon a gas station selling 109.5 octane racing fuel. It was called blue something or other. Any way, it was $3.something a gallon, when everything else was less than $1. I wanted to try it, but as a poor teenager, it didn't happen.

It was leaded, so it would be very bad on any car with a cat. Also, since higher octane fuel ignites more slowly, if you were to put it in a standard low compression engine, you might actually get reduced power. higher octane fuel is usually SLIGHTLY more dense, so you might get more MPG, like .5, but at 3x the price, it's probably not worth it
