Do not use synthetic oil for the initial break-inNovember 17 2008 at 8:15 AM

Response to Probably should not blame the oil
I understand Porsche and Corvette, and perhaps others use a synthetic specially formulated for breaking in the motors, as their initial fill at the factory, and this is changed out at something like 1000 miles. I would NOT USE SYNTHETIC OIL FOR BREAK-IN of any motor, unless of course, it was a special blend intended for cutting in. Regular synthetic, such as the Mobil1 15W50 Extended Performance, would be WAY TOO SLIPPERY for a motor to properly seat the rings, etc. (of course that's my opinion, but I would just about bank on that one).
Interesting thing, the super clean 1989 Arizona Bronco I bought to haul my Sea Skiff (yes campers, that's part of the expense attributed to the boat restoration, as Janet's Volvo XC90 had to work way too hard getting that boat up our very steep driveway) had a lot of documentation of synthetic oil changes over it's life. I recently filled it with the Mobil-1 15W50 and it's as happy as a clam, with 120,000 on the odometer. The darn thing runs like a new one.
Funny thing about the Bronco, besides looking like the one OJ was driving, it was actually owned by Lyle Lovett's drummer, ha! Fuel consumption you say? A lot better than a Commander.
