I'm a history teacher, not an engineer. And, I'm very old school and probably overly conservative with OCIs etc. Even I spotted some questionable stuff.
1. 2000 mile OCIs? This is patently untrue.
2. He seems to be implying that 3000 mile OCIs are necessary when using synthetic. Although I have yet to go 10000 miles on a synthetic oil change (and probably never will), I knew even before I found BITOG that synthetics could go beyond 3000 mile OCIs with the right filter.
3. He states that extra oil should not be added until the engine is down 1 quart or more. I fail to see how adding a half a quart if necessary is harmful, assuming the crankcase is not overfilled.
4. Most Americans drive exclusively in the city? This guy needs to see the USA in his Chevrolet. In fact, I was born and raised in Jersey and I can tell you that many, many people who lived in NYC didn't even own a car because of the expense. Look at a map and see that the majority of square mileage in the U.S. is still suburban or rural. The world is not one big traffic jam.
Anyway, this is the stuff I saw.
