[Healeys] Test--is the list down?

That is completely consistent with my understanding Mike,

Question for Bob. Through my aircraft engines training and experience and many years in the automotive industry I have learned that "octane" is only one of many properties of gasoline which have affects on engine performance.  Octane is a measure of fuel's resistance to pre ignition and has been grossly over sold to the unknowing public as "the" measure of the quality of fuel. There are many other properties of gasoline which can profoundly affect the performance of gasoline but these are seldom mentioned. 

As I understand it as long as the octane rating is high enough for the effective compression ratio of the engine in which it is being used higher octane rated fuel is of no benefit. Is that a correct statement?

Bob--

 

I live in MD where both 93 octane gasohol and alcohol-free fuels are available.  Aside from some gasoline-powered garden tools for which I bought the long-lasting stuff they sell by the gallon I have always used pump gas.  

My 2007 Tundra was great in that it would run on 87 whereas my Audi A4 requires 92--which works out to 93.  

As for the Healey I always use 93 gasohol though I think I am wasting money and could probably get by with 91.

As for my Ginetta G4 (Ford Kent precrossflow) and Elva MK IV (Coventry Climax FWB) race cars I buy unleaded high octane (110) at the track and pay whatever I must in order to play..

OK, I'll get the ball rolling.

I have a background in chemistry, and have always been interested in stuff chemical, including motor oil and fuel. This is, to me, an interesting take I hadn't given a thought to before. I've always run premium in my Healeys, Lincoln (required) and Mustangs (of course) and my two-strokes* (chainsaws, blower, trimmers), but have made do with regular--mostly Costco--in my other equipment (Ranger, tractors, mower, edger, quad, squirrel gasser, Gator). My engine builder told me the engines he sees in the best shape have been run exclusively on Chevron premium, so the Mustang and Healeys get that whenever possible, the Lincoln and two-strokes get Costco 91; everything else gets Costco 87 (note Costco gas claims to be 'Top Tier'). 

* My Stihl 4-stroke string trimmer specs 89-octane, but Costco only has 87/91 so the 2-stroke mix gets 91.

It's just been very quiet on the list lately. Seems to be less busy, I guess everyone's cars are all running just fine! Ha!
