Question:
What's the Shelf Life on Opened Bottles of Mobil 1?
I could not find an exact answer in the FAQs. I did read that Mobil 1 has a maximum shelf life of 5 years for un-opened containers. Is this true also for opened containers? I have a quart of Mobil 1 Extended Performance (15W-50) that is eight months old, kept in a cool dry place and was wondering if is still good to use and what is the shelf-life on open containers? Thank you very much!!

Answer:
An 8-month-old oil, even opened, should work well in your engine. As long as the bottle is capped and kept dry, the product is safe to use for up to 5 years. Keeping it cool and dry are the key conditions to control degradation and additive drop-out.
