Mazda 5w-30 shelf life?
Hi all
I have looked around the forum and on the web and cannot get a definitive answer on how long Mazda 5w-30 oil can be kept on the shelf before it is best to replace it. I have two 5 litre bottles that I used for topping up purposes. One is about 3 years old the other only 12 months.
Some dealers I have spoken to say max 6- 12 months before throwing it out. some say its fine indefinitely???? It is just sitting on the shelf in its sealed container.
It is the Mazda factory oil API-SL 5w-30 Any feedback appreciated.
Thanks
Ice

That's what I am getting generaly. Either its fine for ages, years perhaps. Then I am told no, it is a mineral oil that should not be kept once opened for more than a year.
It cant hurt to have some fresh oil though, so I may go buy a new batch.

i wouldn't say it has an indefinite lifespan since the additives in the oil will break down over time and offer slightly less protection but you likely aren't going to let oil sit on the shelf for 5+ years anyways.
