If I was a billionaire I would have some fun. I would have numerous vehicles undergoing different lubrication test. I would like to run a class 8 truck on 5w30 supertech dino @40k oci's, a Dodge cummins truck with 5w20 dino, a new Honda accord using an old API SA oil, a Audi with Mobil1 10w30 EP with only filter changes to see how long it could go and on and on.
