    What if?

    What if you have two 5 gallon cans of kerosine and you don't remember if you put turbine oil in them?
    Would you throw it away or just add another quart just to be on the safe side? Never done this before.
    I don't like getting old. Thanks, Mike

    Mike too much oil is as bad as not any. Instead of the balls rolling they skid and that is not good either. If you had 2 five gallon jugs would not one weight a little more with oil in it. Maybe you could weight the two if they were alike and figure out.

    I wouldn't think it would be a good thing to add double oil to the fuel, if that is what ultimately happens if you've already added and now add more. Isn't there a way to test the fuel to see if oil has already been added to it? I've been involved with salt water aquariums and we test the water for different things with a very simple test kit. I'd think there would be test kits for turbine fuels as well which would work sort of the same where you take a sample, add in some chemical and see what color it turns, indicating turbine oil.

    Thanks Kevin. Just to be on the safe side I think I will put it in my Motorhome tank and and start over.
    Not worth taking a chance.

    Why not mix them both together and add another quart!

    For each jug in question, pour a small amount into a glass jar and set it out in the sun. If oil has been added you should see an oily residue left in the jar after the kero evaporates.

    Actually, if its turbine oil. put the glass jar in the sun and if it turns darker, its got oil in it.

    Personally, I make it a rule to *never* fill a jug with kero unless I put oil in the jug *first*. That way I don't have senior moments about whether or not its got oil in it.

    Get another 5 gallon jug fill it with 2.5 gallons from each of the unknowns and put in one pint of oil. mix the remaining left over together and put in the remaining pint. Simple. If you can't find a 10 gallon jug

    Better safe than sorry so dumping it in your rv is a good option. Only thing I would add is if the motor is an AMT, just add another quart and run. I've had similar brain stoppages and figured what the hell just add another qt. motor didn't know there was an additional qt.

    better safe than sorry with these newer / lighter engines.

    Good luck

    How is this different that adding putting a quart into 10 gallons?

    What if, you call Bob Wilcox. I'm sure he's heard it before.

    It's very simple really.
    Do you want to save money on some fuel and possibly ruin a few turbines in the process.
    Its a no brainer.

    I've been through this before and my turbine seller just told me to add more. That's what I did and no problems accept a little extra smoke

    keep the fuel and mix a gallon of it to each future 5 gallon jug that you have already properly mixed. That will lower the percentage to 4%, worst case.

    Of course this assumes you are mixing 5% (4.8% to be precise)

    Do a burn test with a small amount in a small metal container. Use a pie tin or something similar. The kero will burn off and the oil will remain behind if it is in there.

    Fairly sure I had same last year and compared the questionable kero with some that definitley had no oil by pouring some of each into separate jam jars and visually comparing. If it's oiled you can see the globules?

    Mike,I think you have answered your own question.

    Motto:- if in doubt chuck it out!

    Mike listen to your head and chuck it out as mentioned.
    Fuel is worth nothing compared to a turbine and possibly a jet if the failure happens in the air.

    Just a quick question to to Original Poster. If it was turbine oil you added, was wondering if you took 2 clear jars and added fuel from each jug into each jar. Wouldn't the fuel with the turbine oil be a tad darker in color than the Kero without it? When I worked on Jet engines we used turbine oil if memory serves like aeroshell among others. All of them were brownish orange in color.

    Seems that in a 5 gallon jug you would be able to see the darker tint in a clear jar.

    I've gotten close to being in the same predicament, but I now put tape on the handles and label them as mixed or not mixed to be safe!

    The oil, being heavier than the kero you would think would settle to the bottom of the jar?...because if you see globules, then it could more than likely be water in the fuel.

    Thanks

    I was in the same situation, But I solve the problem by pouring both in two separate clear drinking glass and observing them together. I was as clear as day which have oil in it. I'm still pretending to my wife I don't know where both glass went

    Been there, ran 10% before. Smokey in a jc rabbit.
    I always wonder if 1 liter would have a weight difference..

    I like the motor home fuel idea. Not the cheapest fuel but good way to burn it
