Is there an easy way to check Octane Level

I need to do final calibration of my
engines. I put race fuel in at the Lake
Cumberland poker run last Fall and only used a part of it. Now I need to do final ECM calibrations with 91 octane. I have no real way of knowing what I have in there. Any easy way to measure this?

Do a lab test.... I can get you the contact info for who does all our fuel samples

Thanks, I'll get a sample and get it to them. Is the lab in Owensboro?

I was told several years ago that it's a very expensive test.....true?

If not, please PM me that info as well.
Thanks,

Doesn't the race fuel last longer?

There are kits you can buy. A speed shop near me has them. I bet if you google test for octane that a million things will come up. I got to imagine those tests from a reputable company like a Holley, or Mallory or..... would be accurate enough.

Our race fuel has consistenly held its octane level over 12mo's..... We test ever batch we blend before shipping....I will get you the price and address when I get back to the office. You can test some things without a lab but I am not aware of anyway to check octane fuel in house without buying a very expensive hydro machine. We can test specific gravity and lead content in house and thats about it.

maybe in sealed air tight drums ,definetly not in an open environment or boat fuel tank

Drums aren't air tight the screw in bung caps are made to breathe....that is so the fuel won't explode the drum or spray you in the face when you open it (even though it still happens occasionally in extremely hot temperatures). Fuel would be more opt to lose octane in a open air enviroment where it is losing more fumes though.

We use Dixie Labs and the cost is roughly $450/sample. I would say at this price you are better off to drain the tanks as mentioned before.
