(yes) Still, it's really not going to cool down with the engine running unless you leave it running for 10 minutes or more. I suggest you wait 30 seconds after pulling up to let the turbo spin down to idle speed AND using synthetic oil in any turbo motor. Back to the OP's question: turbo spin-down used to be a more serious issue when turbo units were not water cooled. MY .02, Bob
