Red Solo Cups and Diesel

Red Solo Cups and Diesel Fuel Don't Play Nice Together: Need a little container for draining a Racor fuel filter? Don't use a red Solo cup!

File this one under OOPS. Yesterday Dave went to drain the Racor filter and grabbed a red Solo cup to do so.

Great; it was the perfect size to fit the space in the engine compartment. He even made a comment about how much easier it was than the bottle he’d used the previous time.

After draining the Racor (mostly diesel fuel), Dave set the cup down in a drink holder while he put things back together in the engine compartment.

Five minutes later he spotted diesel fuel on the cockpit floor. Tracing it back, he found that the diesel had eaten holes in the bottom of the cup.

We won’t make that mistake again.

The Solo cups have a recycling number 6 stamped in the bottom, I assume that any cups with a number six would be a problem. In a quick Google search, it turns out that #6 plastics are styrofoam and its relatives (polystyrene).

Hmm, I knew that styrofoam melted easily with many chemicals, I just didn’t realize that red Solo cups were made from “styrofoam.”

  1. I once put the fluid from our compass into a water bottle for temporary storage. Didn’t hurt he bottle any but while it was sitting there somebody picked it up by accident and took a drink!

  2. We put gasoline in a solo cup once… Oops!

  3. Use a plastic milk jug. Made of HDPE, same stuff as the plastic car bumpers and in my case my water tank.

    • Mike, no way is there room in the engine compartment under the Racor drain for a plastic milk jug. This was what he was draining the Racor into until he could transfer it into something “better” (such as a milk or water jug) to take it to the recycling center.

    If my memory serves me well, number six is PS, or polystyrene. So called styrofoam is EPS or expanded polystyrene. Cheap but not impervious to petrochemicals and oils.

  5. water bottles work, mixer bottles like tonic water etc also work. We have a pocket that holds several mixer bottles of diesel for filter changes.

  6. Empty quart lube oil containers…

  7. I find that containers with recycling numbers 2, 4, and 5 work for most things. 2 and 4 are High and Low density polyethylene and 5 is polypropylene. Those “semi-disposable” food containers they make now are usually one of those and I’ve found handy to have around outside the galley.

    Be glad it was only diesel and not something like gel coat or your mess could have been much worse.

  8. Holy crap! Good to know.

    Incidentally, last time I was in France one of my co-workers asked me, “Do all American parties really have red cups?”

      Gimme Shelter, that quote had me laughing. It’s like everybody thinks we ride horses here in Texas.

  9. Your timing is incredible – as always. I’m changing my fuel filters today! Thank you!

  10. one red solo cup filled with gas from a jerrycan by the bikes by the trees and carried to stoke up the wet fire resulted in a flame that went from the throw point up the arm then trailed back to the trees, jerrycans and bikes. makes me laugh now but seeing my guy at the time go up in flames well…lesson learned

  11. Need to ad rum and chug-a-lug it!

  12. Made the red cup mistake when bleeding the fuel line last year – can be quite messy.
