I have never heard of that. My Dad uses Peanut oil for cooking everything, I might have a hard time trying to use a bottle of his
All the valve cover and oil pan gaskets I get are rubber, so not sure why he said that either??. You should have countered him by saying "then why is there a rubber gasket on an oil filter?"
There are also many types of rubbers today. The type a tube is made out of, I would think engine oil would deteriorate?
I just hope he's not pulling your leg? like when I was an Auto Mechanic and I would ask people if they rotate there spark plugs every 5k miles. ( as a joke)
I think you misunderstood. The mechanic wasn't saying you couldn't use oil on rubber. When I asked about the oil deteriorating the rubber, he basically said, if that were true, then why do they make rubber valve cover and oil pan gaskets, that are in contact with oil. And as you said, there is a rubber seal around the base of an oil filter, which states on the directions, lube the rubber seal with used engine oil before installing.
