Sounds to me like there's something funny going on in schoolbus-land! In my career as an owner of a bunch of used cars, and a sometimes european-car mechanic, I've probably switched 100 or more cars to synthetic, with mileage ranging from 20,000 to 250,000. I've never seen anything close to a severe problem doing this. What I have seen: Higher oil consumption/leakage, presumably because the synthetic flows more easily. Mainly affects engines that had pre-exsiting problems. Increased valve-lifter noise. Can't quite figure out why this is, one theory is that the synthetic "breaks loose" existing dirt in the motor and it finds it's way to the lifters. What I have also seen: Increased gas mileage. Not huge, usually 2-3 MPG. Easier starting when cold. Reduced engine wear. I've got a couple of 900 turbo motors in the garage with > 200K miles, you can still see the hone marks in the cylinders, and all the bearings meet "new" specs. Longer turbo life. Bottom line: synthetic is all I'll use in any of my motors, right down to the lawnmower. And transmissions, diffs, etc. where appropriate.
