Who knows of any recent engine that has failed because the oil went bad?

So far I have never heard of any, modern or old normal engines that may have failed because the oil failed or too much dirt caused it to fail. Of course, I want to hear some science to back up the diagnosis, not 'it must have been the oil'.

Don't know but I have seen (and heard) many more modern cars running like crap because of stuck hydraulic lifters... could it have been caused by dirt and varnish??
