Why "Honest John" is a tosser 204

OK, I was right, here is the first part of one of his FAQ's. 8. What's the best way to run-in a petrol engine? "Put the car on a rental fleet so it is driven by a lot of different drivers with different driving styles. Seriously, modern petrol engines are built extremely 'tight' so they need a bit of wear during the first 10,000 miles for the piston rings to bed properly into the bores. An early oil change to fully synthetic can prevent this happening, as can driving at low engine revs and driving at steady speeds. So, depending on the engine, self-impose yourself yourself a rev limit of between 4,000 and 5,000 for the first 1,000 miles, and be sure you vary your revs and occasionally reach that limit. After 1,000 miles, common sense dictates that you won't rev the nuts off the thing straight away, but you needn't be too worried about hitting 6,000 rpm occasionally as long as you vary the engine speed." That's his theory, but I'm not saying that I agree with it.

I've always understood that the best way to run in a modern engine is to let it rev fairly freely, but avoid labouring it at low revs, and vary the speed from time to time. This would agree with what is said above. My fear of a rental car would be the many drivers who stuck it in fifth at the earliest opportunity and never let it rev. DavidR's point is a good one - a rental car will have been driven badly at some point, but also driven well at some point. The "one owner" car may have been driven all its life by a total cretin. You pays your money...
