I wonder how many of the sludged motors were in leased vehicles? If a person does not own the vehicle, what is their incentive to maintain it properly?
Unfortunately, we will never know the truth about sludge, whether it be in a VW, Lexus, Toyota, or anything else. The reason is two-fold:
1. The drivers/owners-or-leasee(s) of any vehicles that were not maintained properly are not going to be honest, because of their own $$$ concerns.
2. The manufacturers won't give us the truth either, because they don't want to admit they make engines with design flaws.
FWIW, I bought a new '99 Toyota Tacoma Pre-Runner in June '99. It had a 2.? liter 4-cyl engine. I did 8k mile OCI's for 44k miles, all service done by the Toyota dealer & when I sold it in '01, the inside of the valve cover was clean as a whistle.
