When I fill up my truck I've been putting 5 gallons of diesel into cans to save for upcoming hunting trips to save a few dollars. This diesel has been stored for about 6 weeks and wont be used until mid August. Is this ok to do?
It generally depends on how good the fuel quality is to begin with and the conditions it is stored in, but you can usually store diesel for about 6 months. Weather plays a big factor. If you live in a hot and humid climate, the storage may be as little as 3 months. If you live in a cold and dry climate, you may be able to store it for a year or more.
Its always a good idea to dose the fuel you are going to store with something like Power Service or Stanadyne...
me and my dad own a lumber company and we buy huge amounts of diesel and store it in an above ground tank the last tank we used it over a span of about ten months i put some power service in it all and it kept fine
