Hey Guys,
How can I tell when my nitro fuel goes bad? I have a quart of NVX15 I bought around August.. Never opened the cap, stored in dry environment.. Is it still good to use?

yep its still good, moisture is about the only thing that kills it.

if your still unsure try it.

Normal nitromethane is pale yellow in color. If nitromethane becomes blue in color it may be contaminated, and be dangerous to handle. Do not use blue nitromethane. Immediately dilute blue nitromethane with twice it's volume of methanol alcohol and consult Klotz S.F.P., Inc. for methods of disposal.AVAILABILITY: KL-661 gallon; 30 & 55 gallon drum Klotz Special Formula Products, Inc. * 7424 Freedom Way * Fort Wayne, IN 46818219-490-0489 * 800-242-0489 * 219-490-0490 fax * www.klotzlube.com * [email protected]®LUBRICANTS

Hi Steve,

Could you explain more about the blue nitromethane? Is it toxic or explosive when in blue color? Thenks for your input

Oops, Pylanton was not asking aboot straight nitro, sorry.

nsxrr, I would think it would be explosive, but I really don't know.

Light will break down the nitro in the fuel. I always store my fuel in the cardboard box it came in.

Hi Gang,
I know from working with different refrigeration oils some will grab moisture right out of the air.
I was just thinking if any one had info on how hydroscopic the oil in R/C fules are

Oil is not hygroscopic, methanol is very hygroscopic. Nitro is somewhere in between. Concentrate on keeping methanol and mixed fuel dry.

. Thanks very much Ross,
I had a feeling that it may be and I see a lot of R/C car racers just leaving the cap off the jug.
Not a good thing to do especially on a humid day.
Thanks for the info
Have a great week
