A friend of mine asked what oil I thought would be good to use in his 150,000 mile truck. He has owned it from new and always had the dealer do religious 3,000 mile oil changes. He is a competent restorer of old cars and has decided to start DIY maintenance of his modern vehicles.
He takes excellent care of his vehicles and the truck runs perfectly. Smog tests are likewise very clean. No oil leaks and minimal oil usage. He lives here in Northern California, so most of the weather conditions are mild.
I recommended that he run one of the 15W-40 heavy duty oils such as Chevron Delo or Shell Rotella which are both widely available here. I also suggested a Motorcraft filter as an easy to obtain quality filter at a reasonable price.
He picked up the Delo and a Motorcraft filter today.
Personally I think that for his application synthetics oils would be a waste of money, especially if he is most comfortable with a 3,000 mile change interval.
Does anyone want to try and talk me out of these recommendations?
