Robert Civil aviation standard for drum stock is 12 months then retest. Store with drum bungs horizontal under cover.
You can use in your diesel car however common practice is to add an additional lubricant eg auto trans oil or two stroke as the low sulfur reduces lubricity. Buy a new DG approved jerry can and buy fresh fuel when the engine turns up. Fuel fungus is an issue if any moisture gets into the storage drum and grows on the fuel water interface. Will block fuel filters very quickly and resembles a fine filament. Make sure everything is bonded as Jet is a Dry fuel which builds static easily. Regards Peter Heath ---- Anthony Smith <[email protected]> wrote: ============= Robert I can make some enquiries for you. Some very rough answers: 1. Defence stores Jet A-1 (that is A one) for years in bulk supply tanks. It is a heavier fuel and takes an awful long time for the lighter constituents to evaporate away (flash point increases as a result). They do a flash point test to verify that it is still OK to use. 2. The quality of the storage container will determine rates of ingress for particle contaminants and water. 3. Anecdotal evidence says yes. Jet fuel is typically a 'finer cut' than ordinary diesel (which has a broader temperature range of constituents). If anything your car will run far cleaner than diesel with less deposits. Most military aviation organizations are using jet fuel for the diesel vehicles and generator sets now. Saves them carting two kinds of fuel around. I am not aware of specific alterations to the vehicles to enable jet fuel use. Some manufacturers of cars do not recommend the ethanol -diesel due to the lower flash point (ignition temperature). 4. Sulfur content is really based on source of the crude and is highly variable. There is technology creeping into the refineries to remove some to most of the sulfur. Look at mercaptan content if you can get the data - can be broadly classed as Thiols. 5. Given that you are likely to buy a reasonable quantity and use it sparingly over the course of 12 months: All the usual issues with long term fuel storage.

The advice is that I should use Jet A1 rather than diesel as it must be low sulphur diesel and that is hard (apparently) to guarantee here. So I beg your indulgence about a few issues 1. What is the shelf (or tank) life of Jet AI? 2. Will that shelf life depend on the sort of tank it's in (aircraft, jerry can, 44 gallon drum etc)? 3. Once Jet A1 has passed its (aviation) use by date, can I use it safely in my diesel car (as that would be a way to avoid throwing it away somewhere). 4. Is low sulphur diesel really that hard to find (guaranteed) here in Australia? 5. What other things should I be thinking about in terms of fuel? -- Robert Hart [email protected] Darling Downs gliding weather information <http://the-white-knight-speaks.blogspot.com.au/> +61 438 385 533 _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
