Evenin all,

I have a need to stock up a bit of ulp, not just cos price dropped, but anyhow was wondering if any issues putting in diesel containers.

I have a few of the yellow diesel containers, used for diesel, but dont wanna buy a heap of red uns just for this.

So I'm thinkin.... a dribble of diesel in bottom wont make any difference if filled with unleaded?

and vice versa going back to diesel, shouldnt matter if a capful of unleaded remains in container before filling with diesel again?

any opinions?

I think the ratio of 'cross contamination' would be too small to be significant???

Hi Ron,

I have the red ones and I know you have stated you have the yellow ones but I constantly switch between ULP and Diesel and have had no dramas.

Ron, I do this regularly. When I travel, most of the gerries are full of diesel. When camped, I regularly fill them with ULP for the boat and gennie.

Provided you ensure they are as empty as reasonably possible, there should be no problem. I have not had any anyway.

I use the black gerries for both. I think the red / yellow colours are just for identification, but not certain on that.

??
Yellow = Diesel (or ULP if need be) (Willow)
Red = Petrol (or Diesel if need be) (Willow)
Lite Blue = Water (Willow)

Black = whatever fuel? (Rheem)

As said above, yellow & red can have either fuel, as long as you know what's in there.

Sprint-GTO ,, what the?? Yellow =Diesel - Red = petrol ,, STANDARD colours used world wide by Nato ect , White / light Blue / Blue = WATER , Green plastic jerries are imprinted with the words "WATER ONLY" so as not to be confused with green steel jerry cans.

Michael , think you will find that not all jerries are made the same , different forms of "plastic" for different purposes ,not just colour , water jerries must be 'Food Grade ".

Gday Axel,Hows it going?
You are right about food grade for drinking but it is still HDPE! the cost of food grade and non food grade are the same, you just have to specify what you want when you purchase it. I think the general conversation was about fuel containers and only HDPE is suitable for fuels. I have been in the plastics industry for over 30 years and i know no other suitable material that you can use for a tough container that doesnt soften or change shape with fuels. You can get some super tough Polypropylene grades now but they still dont like petrol or most chemicals, they change shape after fuel sitting in them for a prolonged time. Michael

+1

water container should be food grade --- also i got mine from bunnings -- it has the word " WATER" molded on it AND its a clear typre plastic so you can easily see if your container is contaminated or dirty ....

I can hardly dissagree with using food grade for drinking but i meant specifying from a manufacturing point of view. Michael

Keep in mind that you should use petrol within 3 months. It does go old. I have used 12 month old petrol but there was a definite lack of power.

I inherited my truck from my father, and he had a Jerry can bolted under the tray for spare petrol.
Thinking it was empty, I never bothered getting it out, till passing through Port Augusta heading west on a dark wet windy night.
Bloody thing was full of fuel from about 5 years ago, and I had just filled the tank.
Didn't use any of it till we got to Perth, thinking it might cause trouble. We 'shandied' it out to the tank over a couple of weeks while we were near towns and did not notice any difference.
Reminds me... must use the fuel now in it, very soon, must be at least a year old.
cheers

Boobook2,

I have often heard/read this with regards to fuel going "off". What I want to know is if it is in an air tight container how does is go "off". I would have thought it was like a can of food and once it is sealed and no air is getting in then it should in theory stay the same???

I was low on fuel coming into Broken Hill one night, i had 40 litres of diesel on the front of my trailer so i put it in the tank. It spluttered and coughed all the way untill i filled up again in broken Hil. It had been sitting on the trailer in black Rheem containers for 12 months in the back yard. I found no water in the sight glass, I think the sun and the heat drawn by the black containers kill the fuel quicker than if was sitting in a cooler spot, say in your garage.. Michael

Hey all.

Fuel degrades an octane rating every 2 to 4 weeks, depending on your environment. The chemicals break down, regardless of interaction with air, although if exposed to air the breakdown is quicker. Hotter equals quicker.

Its noticable more / earlier in high performance or small capacity engines, especially under load.

I've seen "people" put a couple of litres of ULP into a tank before realising the mistake, and filling with diesel. ULP has higher octane, and is not meant to be compressed to the same degree as diesel. Up to a point its adding power to your motor. After that your only adding holes!

Cheers!

Hi Michael,

Not saying it was or wasn't the old fuel as it may have well been but another thing I was thinking it could have been was the dregs in the tank running so low. I make a point of not filling up at servos that have a tanker dropping in the fuel and stirring up the bottom.
