Two Cycle Oil Shelf Life

[Grabber48]

Anyone ever heard of a shelf life for 2 cycle oil. I bought a boat and the owner through in a case of oil that I think is about 6 years old, he hadn't used the boat for 4 years, I had to dump a tank of mixed gas that had sat for that long but I don't think unopened oil would deteriorate?

Thanks in advance

It wont, sealed in bottles, etc. Your oil is fine if a good quality brand.

From evinrude.com:

Q - I have some oil that has been sitting on the shelf for a few years. Is it any good? Can I still use it?

A - Yes, just shake it up and it will be fine (it may need to be room temperature).

Q - I have a lot of TCW-2 oil. Can I still use it in my motor?

A - Yes, as long as it's a 1992 or older motor. You may want to use Carbon Guard to minimize the formation of carbon deposits in the engine. Using TCW-2 oil in a motor that requires TCW-3 oil will void your warranty, should an oil related failure occur.
