Hey Folks, I own (almost) a $45,000 sticker price automobile, which I did not pay that much for of course, with a handbuilt AMG $13,000 engine. Someone way above my pay grade decided that 0W40 MOBIL 1 was the oil to use. I am not going to bet my Blue Boy against a few $$$$ for some cheap a** sludge builder to save a few bucks. To each their own, but I just bought 17 qts of Mob 1 @ Pep Boys for $6.99 each. That's enough for 2 oil changes, for a total of 15,000 miles book recommended. I cheat a little and change the filter at 5,000 miles add some, and then change both oil and filter at 10,000 miles or less. So what's the problem? That's a year's worth of driving for about $125. I don't hear about anyone using 87 or 89 octane..
