Check with Mobil like I did. Their synthetic blend is 90% conventional oil/10% synthetic. Nothing special or unique about the additives. The only creative thing they are doing is with the pricing. Mobil conventional goes for $1/quart and synthetic $4.75/quart. Somehow Mobil arrives at a price of $2.50/quart for the synthetic blend.
Dick, maybe some people wait until conventional oil is oxidized/broken down, but test data have shown this typically happens in the 10-12K mi ballpark. Vehicle manufacturers recommend oil changes in the 7-8K range, and most people change in the 3-4K range. The base oil is still perfectly OK- you change the oil to refresh additives- that is the weak point. That is also the weak point of the argument for synthetic oil.
