Save your money. Seriously. Unless you are top pro, just twist the throttle more.
Or really cut that down, say 1 gallon of C 12 for 4 gallons of Pump.

Tehachapi is 5.73 for 100LL as of Nov 7. .

Just called a airfield and they won't sell gas to the public why. How do I get it ?
LA County airports won't let you inside the fence. I get it at Cable Airport in Upland. They are really cool about it. they do a fair business as it helps them keep fresh gas in their tanks

Does the vp haves options for t2 vp gas that's what I need vp t2 for my 2 stroke

More false info. Most hydrocarbon blends freeze or slush at around -70F or less on their own. Some hydrocarbons begin to slush at -135 to -140 on their own.

Also, AV gas is designed for max power, max load, and detonation resistance during take off at sea level.

Not sure if it’s any cheaper, but there is a station not far from you that sells VP out of the pump. You’ll have to see what VP it is since I can’t remember off the top of my head but have had friends get it from there multiple times.

No, it’s not a big name station. But from what I’ve been told, the VP there is quite a bit cheaper

I didn’t know about that station. There’s one in Lancaster and another one in Van Nuys on Sherman Way and Woodley that sells Trick 101. I believe there’s also another one in the Chatsworth area as well that sells VP

Ok can u ask them for me please and ask if they have selections like t2 there for 2 strokes ?

It wasn’t always that way. I had a muscle car with solid lifters that would only run on aviation fuel and it always amazed me (and frightened) how easy it was to get the gas. You will be fine.

Don’t call, go on http://airnav.com/ and find a local station that is SS self serve. It’s that easy. Type in my tail number when the pump asks, it’s “000”

When doing self serve at an airport, the computer screen, where you swipe your card will always ask for a tail number. Just make it up, its never mattered. I used that airport about 1.5 years ago, I'd be surprised if they changed, bummer if so.

Park by the gate, walk into the office, 1st or 2nd door on the right inside, tell them you would like to get fuel, they will open the gate and you drive up to the fueling station.

I know this is a 100LL thread, but here's an interesting Leaded vs Unleaded writeup from Renegade for those who need clarification.

IIRC, you’ll need to jet a little leaner due to 100LL having a lower specific gravity than pump gas.

Wouldn’t agree with Renegades lead claims 100%. Hardened valve seats in US car/truck engines were introduced in 72-3-4 depending on the make and model. Older engines don’t all agree with unleaded.
As far as dirtbike engines. Excess lead will gum up power valves and ports on two strokes. Doesn’t hurt four stroke valve seats. Does lubricate the valve guide some also to a degree. The cleaner the fuel and if it’s octane meets your engines needs to eliminate knock. Is better in the long run. Unfortunately today there is quite a difference in consistency of most pump fuels. Then add in winter blends and chemicals. If we could just buy non ethanol fuel. Storage problems sure would be drop.

People will say no, but you can with no issues. I run it half and half with 90 octane non-ethanol gas. I've heard the argument that it's designed to run at high altitude, but where does a plane need the most power? To get it off the ground is when. Many race gas companies use it as a base for their fuels.
Actually, the formula is more dependent on where you are flying from. Some areas of the country are very flat
and there's no need to fly at high altitudes. So the formula is different. Per the instructor in class.

Actually fuels with a lower Specific Gravity are less dense, so you are getting less fuel through the same jet size meaning you would need to go larger on the main jet. In reality most engines are jetted on the rich side, so running avgas leans the engine out a little which may show an improvement in HP as long as you don't go to lean. Avgas is higher octane (but don't confuse Aviation Octane Numbers (AON) with Motor or Research Octane Numbers (MON/RON) as they follow completely different testing criteria.

I thought due 100LL being lighter, given the same amount of vacuum it would pull MORE fuel...? Maybe I'm wrong, that's just what I remembered reading.

It's a nice marketing piece I guess, but that's all. ie: TEL has zero BTU content, and being heavier or more dense has no correlation to energy content. Water is heavier than gas and has a BTU rating of zero. And higher RVP is not necessarily a bad thing...Higher RVP is what makes your car easier to start on cold mornings, and lower RVP helps it from Vapor Locking in hot weather. I know the gas powered RC guys use to run VP C-16 only because of the low RVP, as it was the only fuel that would not vaporize in the fuel line.

That's an interesting thought, I've never heard it before, but I understand how it could make sense. API gravity uses different numbers and you might be thinking of that.

A bigger factor is the temperature of the gas. Gas expands a lot and the difference between running 60 degree gas or 80 degree gas through a jet is significant. All lab testing is done at 60 degrees
