is ur garage climate controlled and air purified like OntheReel's??Oil and tranny fluids have a decent shelf life. If you can keep it in the house you probably can get 5 years! I have kept Amsoil in the garage for 3-4 years. It still looked good. (10w-30 for the lawn equipment and 0w-16 for my dad's car...so that I can do the work for him when he stops by) Brake Fluid does not last long. Max 12 months if factory sealed. If it is opened. maybe 2 weeks.
