Carbon Cleaning Engine thru running it hard

[clivealive44]

Hi, I saw this comment on a thread about the above subject from a 25 year time served mechanic on Quora
"When I do tune ups on Alfa Romeo (especially spiders) after the filters, plugs etc I would take them on a 10 mile trip to burn off carbon build up in the cylinders. I'd take first gear up to redline and take my time on the one two shift due to the difference in ratios then run the hell out of it from second gear to fourth gear spending about a minute just below redline then when the owners would leave I'd get a call later that day or the next swearing I was a god because it hasn't ran like that since they drove it off the lot new. At which time I'd tell them to take it out on the highway and drive it in each gear for a minute at redline about once a week depending on how often it's driven and how often in stop and go traffic. And the Italian cars are something like a race horse and need to run wide open or they foul up and get hard to start, gas mileage drops, and they get unpleasant to drive. I would apply that to any high-performance engine from any manufacturer I know my uncle's 69 boss 429 Mustang didn't like to drive in town it would foul plugs and snort but take it to the drag strip and it was happy as a hog in a mud water. "

I was wondering whether it would be advisable to do something like this on an old D24tic engine. I've had my 1996 Volvo 940tdi for 14 years, it has 280k on the clock, 170k I am responsible for. I rarely take it above 3k revs, and more recently rarely take it above 2.5k revs, and do mostly city driving. Any experiences, or advice welcome.
