For the most part... some turbo diesels are 18:1 or so, but normally
aspirated diesels are 22:1 to 25:1 CR

the rate of combustion would be too high and the detonation resistance too
low... Basically would blow the heads right off the engine!
(Seen it happen on a mercedes 300D... guy filled up with Regular gas and
drove off... about a block later, heard a large BOOM and he was at the side
of the road with lots of smoke...  Opened the hood and it appeared to have
sheared the head bolts... head was about 1/4" above the block!)
