Question: I’ve had a new quart in a never opened plastic quart bottle in my shed for about 6 or 7 years. The shed is in a location with hot summers and cold winters. Can I use it? Does engine have a shelf life?
Answer: As long as the bottle is sealed, the oil shelf life will be 10+ years. It won’t be affected by changes in temperature while in storage
Question: My dealer says I have to use the OEM lubricant in my motorcycle or my warranty is void.
Answer: This is not true and may, in fact, be illegal. Have the dealer put this in writing on his letterhead. We doubt he will. All you need to do to fulfill your warranty requirements is to use a lubricant that meets or exceeds the OEM specifications. Spectro products meet or exceed all manufacturers performance requirements. Spectro Performance Oils.
