This has to be a trick question and the answer is blue. Your mixture ratio would be 0% 80 octane and 100% 100LL as the 80 doesn’t exist anymore.

What is the difference between avgas 100 and 100LL?

The key difference between both types is the percentage of the included tetraethyl lead additive. AVGAS 100 has high lead content, while AVGAS 100LL (low lead) includes low amounts of tetraethyl lead, as the name refers. AVGAS 100 is dyed green, whereas AVGAS 100LL is dyed blue.

Can you mix auto gas and 100LL?

Yes, the STC does state it’s fine to mix the two but doesn’t state whether or not the 100ll can be used to boost the octane to meet the requirement.

Yes, you can mix any of our race fuels. But remember – if your engine needs an unleaded fuel, you don’t want to mix leaded with unleaded. The percentage of the 100 octane fuel in the mix is 2/5 = 0.40 ( 40%).

What color is 100LL fuel?

Avgas 100LL is dyed blue. To read more about the fuel, download the Avgas 100LL MSDS now.

General Aviation aircraft with reciprocating engines like the C-172 or C-150 burn Aviation Gasoline. The gasoline is leaded, 100LL is the standard in the US. So that’s an octane rating of 100 and the LL stands for ‘low lead’.

What is the danger of using a fuel that vaporizes too readily?

If the gasoline vaporizes too readily, fuel lines may become filled with vapor and cause decreased fuel flow. If the fuel does not vaporize readily enough, it can result in hard starting, slow warmup, poor acceleration, uneven fuel distribution to cylinders, and excessive crankcase dilution.

What does the 100 in 100LL mean?

Acronym. Definition. 100LL. 100 octane Low Lead (Common Aviation Gasoline)

Lead in avgas prevents damaging engine knock, or detonation, that can result in a sudden engine failure. Lead is a toxic substance that can be inhaled or absorbed in the bloodstream, and the FAA and EPA and industry are partnering to remove it from avgas.

Why is jet fuel cheaper than 100LL?

Jet A fuel costs less than 100LL (avgas) fuel because it is less complicated and expensive to manufacture, less expensive to transport via pipelines, and used in significantly higher quantities leading to economies of scale.

How long will AVgas last?

The short answer is that, under most conditions, the shelf life of avgas is about one year.

Can I run AVgas in my 2 stroke dirt bike?

AVGas works well in 2-strokes, but shouldn’t be used in 4-strokes because the distillation curve is all wrong and will cause a super lean condition.

But if you are just mixing 100 and 91 octane fuel then its simple. For a 12 gallon tank that would be 9 gallons of 91, and 3 gallons of 100. This would bring you to about 93octane.

Does AVgas burn hotter?

The first is that a two stroke motor will run hotter with AVgas. The higher octane of AVgas makes the fuel burn slower and more efficiently. Also the lead in AVgas helps to dissipate heat and acts as a lubricant.

What’s the difference between AVgas and car fuel?

The Main Difference Between Gas and Avgas: Lead

Aviation gas still contains tetra-ethyl lead additives to lubricate the engine. Lead was taken out of automotive gas in 1986. Using leaded avgas in a modern car would ruin components such as the catalytic converter. Conversely, Jet-A wouldn’t work in a gas engine.

What octane booster actually works?

When it comes to the best overall octane booster, we love the Torco F500010TE Unleaded Fuel Accelerator. This octane booster can serve a wide range of engines and boost your car’s octane levels as high as 102. It’s also compatible with oxygens sensors and catalytic converters.
