I have an unopened 2 quart bottle of this oil left over from my KTM dirt bike. The oil is around 10 years old and has been stored in a hot/cold barn for most of those years. Maxima guarantees a 2 year shelf life and to pour out and look at it after 2 years. It's ester based and to my knowledge I have never used an ester base oil and I'm not familiar with its storage properties. I also have another open 1/4 full 2 quart bottle that I have been using in my string trimmer and worn out Poulan saws without any problems. I recently bought 3 new saws and "new" is a first for me. Should I take a chance and use the unopened container in my new saws or just discard it? It's not a money thing but I have been brought up to not waste and it's really bugging me. How about a little at a time in a vehicle crankcase? I have 2 oldies that use oil.
