So I'm at Wal Mart last night and have to pick up some oil for my 2008 Chevy Impala which will be needing an oil change soon. I see that they're now stocking the Ultra...been using Platinum since I bought the car. The 5 quart jug of Ultra is $25.00 vs. the $20.50 for the Platinum. I must have stood there for 10 minutes debating my choice...finally went with the Platinum I've been using. I honestly don't see a big difference in the UOA's I'm seeing here for the Ultra vs. the Platinum (though the advertising on the Ultra jug claims it provides 35% better cleaning properties than their "next best" oil). Is the Ultra really that much better?...(I kept the receipt...just in case)...
