Can you use 100LL in place of engine oil???

[UnAnswerd]

Just wondering, because a member of the CAP almost did. Fortunately, someone stopped him.

Uhhhhhhhh............

 

[jackotron]

try it an let me know what happens

 

[UnAnswerd]

Uhhhhhhhh............

No joke. It occured in the FBO. Guy asked for oil, and was questioned: "What kind"? He then replied "100LL", and was dead seriouse. You should've seen the look on the FBO guys face.

what do you expect from a cap...umm...cadet? yeah. we'll say cadet.

One hundred weight, yes. One hundred low lead, no.Avgas is used in diluter systems to put in the engine oil prior to shutdown, but it's an older system and does more harm than good.

Unpaid bureaucrats are worse than paid ones? I think it was Deming's Principles that said that money was a pacifier, not a motivator.

I've flown the 180/185 with an oil dilution system, although I was under the impression that this was more for start-up in very cold temperatures (yeah Canada) I had never thought of using 110LL or av-gas as an oil. It was used as a dilution so the oil wouldn't freeze in very cold temperatures.

Oh, sure you can. For a while. Then, uke:
watch out, you'll have a problem.
Heck, you can even run it without oil. Just not very long.

 

[GravityHater]

nah, he had a brain fart. He wasn't going to put any fuel in the crankcase, he just mixed up the 100LL with Aeroshel 100W or something.

The real interesting question is... why is Aeroshell 100 a 50 weight oil? Wouldn't it make more sense to be Aeroshell 50? I know. If it makes sense.....

Because the two are different grading systems. Aviation oils use a number which is based on a viscosity index called Saybolt Seconds Universal. This comes from the time it takes a certaion sized oil sample to drip through a specified orificie at 210 degrees farenheit. 100 grade, for example takes 100 seconds for a sample to drip through. The Society of Automotive Engineers (SAE) grade, commonly referred to as "weight" is a different grading system

So, what about when you use, say, 15/50w? Is it just like a car, 15w when cold, 50w when at temperature?

 

[flydrummer]

So basically gas goes in gas tank and oil goes in crankcase. got it!:biggrin:

We had a line guy here try to fuel a Citation XLS through the sh!t chute. That was his last day.

Yeah, the multi viscosity oils give thier grades in SAE values
