Last I overheard, Stanley Cty (VUJ) was the cheap place for fuel.  So

without verifying, I went there to fill up last night...$3.64.  Ouch.



On a related note, I've started cruising at lower power settings, 21 MP/23

RPM instead of the 23/23 I've been using.  Cooler CHTS, at least 1 Gal/Hr

less fuel and 6-7 Kts slower....

Guys, FYI, Elizabethtown, NC (EYF) is pricing 100LL at 3.25 right now. Just 

in case anyone is going that way,

If you guys want to save some bucks on gas, why not use auto gas? Or at 

least a autogas av gas blend?

No not stirring the pot.... if I were to stir the pot I would say something 

to the effect of if you can afford a near 100 thousand dollar plane, why 

worry about how much the gas costs?  Kinda like the owner of a Porsche 

taking his car to Walmart to get a oil change...... lol



Gas is gas and using good premium 93 Octane car gas is a alternative fuel 

that will work just fine in most of our airplanes. I use it in my RV-4 with 

no problems whatsoever. I save usually around a dollar per gallon over 

Avgas.  And for me, price of gas does make a big impact, I am a Walmart 

shopper afterall.

Why use 93 Octane?



If your engine is certified for 80 Octane, like mine, regular unleaded

at 87 Octane will work just fine.  If your engine is certified for 100

Octane, than you shouldn't be using mogas anyway.

I'll bite.  I probably burn 10 gallons of hi-test mogas for every gallon of 100LL... the latest round of avgas price increases makes the $2.85 and up for 93 octane seem more bearable.  Amazing how fast the American con sumer gets accustomed to higher prices.

because higher compression 160 hp engines want to have 91/96?  That's my story and I'm stickin' to it.

I thought the minimum octane rating for these "high compression" engines

was 100, not 91/96.  My mistake.

Maybe for some, Bill.  Certainly not for the 160 hp O-320, though.

Darn it, that undermines my last reason for the 140 hp O-290-D2 I'm

installing my -9.  Oh, there is still that low price thing for a O SMHO

Lycoming, can't forget that.

I was told by many people including the folks at the EAA that handle the 

autogas STC for certified planes, that with my 0-320 160 HP engine I would 

need at least 93 Octane autofuel or av gas. I ran 87 in it for a month or so 

when I got it and at times I could hear some pinging so the 93 makes sence 

to me. No pinging or other issues with the 93.



Bill, off topic but do you really think your bird will go that fast on that 

engine and with that fuel burn?  I have had 2 other planes with 0-290 

engines and both burned between 6-7 gallons per hour at best. In my RV-4 I 

am burning nearly 7 gallons per hour going 170 mph.

Ron,



All I know is what I've been told by another guy who has an O-290-D2

powered RV-9 (Tail wheel), like what I'm building.  His empty weight is

998, and I suspect mine will be a bit higher.



Van's lists the cruise speed for this combination as 175 mph.  From what

I keep hearing, Van's numbers are usually on the mark.



Also, the prop makes a big difference.  Craig Catto cut one for me that

he suspects will get me to 180 top speed.



With all that background info, I sure am keeping my fingers crossed for

a 75% power 175 mph cruise.  The GPH thing, well that may be a bit

optimistic but then again, I'll be burning regular unleaded in that 80

octane, low compression engine



Bill

Ron,



The following was just posted as part of this thread:

it works better than you might think

I had the chance to fly an O-235 powered RV-9A off and on for about 18

months and learned to really like the airplane. As with any RV, you make

engine choices based, no so much on the airplane as the job you will be

asking it to do.



118 hp was good enough to give the 990 lb airplane good take off and

climb and excellent cruise. I'd quite commonly cruise 155-160 mph, which

I though was pretty darn good for that hp -- especially considering that

every other airplane I'd flown with the same engine was lucky to break

100.

	




I may have to rethink the fuel burn a little but if that holds up, my

dream of a 175 mph RV on only 135 hp sounds like a possibility, more so

since I won't have the nose wheel to slow me down.



Bill
