This just hit me like a ton of bricks after picking up some Mobil Super 5000. This is a stupid name. For an oil which is rated SN/GF-5, why on earth would they claim that the product only protects up to 5,000 miles!? Most manufacturers recommend <6,000 miles OCIs. Does Mobil think that consumers will see that and choose to pay more for Mobil 1 instead? I certainly hope not. 90% of consumers would simply put down the MS5K and pick up PYB, etc. Of course I also realize that 90% of DIYers wouldn't even think of this but some definitely will. Of course we all know MS5K can protect for more than 5k miles, I just don't get the business model Mobil is using in this marketing.
