Navi is well known to lecture nonsensical things, so I'm not surprised. He can live his live thinking that oil "expires" after 5 years when there are hundreds of threads and discussions here that flies into the face of his whitepapers. I'll put on my foil hat for a few seconds by saying that most oil companies publish such things to encourage you to buy more of their product vs hedging inflation, plain and simple.Why bother? My uncles small gas yard equipment has been sipping on the same barrel of 1974 era hd30 he got cheap since I was a child up to the present day. No oil related failures yet, maybe someday it will empty.
So Anyone in the know doesn’t need to argue this topic. Reminds me of the expiration date on rubbing alcohol, molasses and c&c white sugar.
