    VP C14+
    Posted by Riley on Thursday, October 8, 2015 8:34 PM

    Just have a question.  I purchased a 5 gallon can of Vp C14 + last weekend.  After I got the can home I noticed it had a date of 2011 stamped on the can.  It is a sealed unopened can.  Will this gas be fine to run or should I contact the seller and see if I can get a fresher can?

    Thanks

    Mr Riley good after noon Jim C from DTR has been in deep discussion of testing 5 Gal sealed pails because what is being found is that the plastic spouts are being seen to leak the front ends out thru that seal watch the video here. http://www.drumpreserve.com/ Also Jim has developed a pretty slick home testing unit and has a video on building 1 for home use. lots of info on the super sled forum on facebook from Jim C at DTR http://www.dynotechresearch.com/techarticles.asp# Fuel Volatility discussion of fuel's "front ends" stale fuel is rampant, testing RVP at home, effect of volatility on combustion chamber conditions Hope this helps. But I would not want a few year old can of sealed fuel . its a *** shoot of fuel running thru you're motor. unless tested.

    I'd bring it back. 

     

     

    Ive decided to buy 15 Gal Drums and I do have the  Drum Preserve kit and picked up a 40 CF nitrogen bottle  to keep fuel fresh and dispence fuel when needed. This seems to be the best bet

    To piggyback off the previous post. We asked Jim Czekala at DynoTech Research about this. Here's his take. As the previous commenter suggests, DynoTech is a great resource for this type of question.

    I would be terrified to use fuel that old in a well-tuned race engine, even in a sealed pail. You must return it and ask for a more recently filled pail (should be a date on the bottom).
    VP’s Chief Chemist, Duane Minazzi, explained to me that the fuel’s “front ends” (ie: easiest to vaporize components like butane and isopentane) can escape out of the flexible plastic spouts on sealed pails, causing a reduction in volatility (indicated by lower-than-spec Reid Vapor Pressure). The “front ends” are vital. They’re the first to transition from non-flammable liquid / globules to flammable vapor in the intake tract. One study indicates that by the time the fuel reaches the combustion chambers, 80% of the front ends are vaporized, but only 20% of the heavier ends of the fuel are ready to burn! So you can see, when the front ends are lost you can have an extremely lean HP-robbing, piston-sticking net mixture in the combustion chambers, even with safe-looking EGT’s (the unburned globs cooling off the probes), and dandy wideband A/F readings (the globs finally vaporize in the heat of the exhaust systems, and finally burn there too late, fooling the A/F gauge). Watch those piston domes!
    It’s quite practical to do your own fuel testing. RVP is a sure indicator of present or lost front ends. I have several informative YouTube videos showing RVP testing on my DynoTechResearch channel. You can also check out the DTR blog (www.dynotechresearch.com/blog) that explains how you can create a Home [Reid] Vapor Test unit for $30 that works nearly as well as systems that cost thousands.

    Never assume that any pail, even one filled yesterday, is fresh because it may have been trans-filled from nine month old bulk or an old opened drum, then sealed. RVP testing is cheap and easy, and if you get substandard stuff you should complain loudly! – Jim Czekala, DynoTech Research

    I contacted the guy that sold the can to me and he said no problem exchanging for a fresh can.  Thanks for the reply's.

    Finally got the can of gas swapped out for a fresh can.  Should be good to go.
