No, I mean gallons. Drain the oil, reinstall the drain plug and then fill the engine, not just the oil pan, with diesel. It should be noted I’ve never done this, but always thought it would be a good way to de-crud a old engine. After letting it soak and after draining the now dirty diesel I’d pull the spark plugs before cranking it over. Can’t hydrolock it if the plugs are out.
Jerry’s (Hotrod Lincoln) method is very good and you could just do a quick oil change with cheap oil and use his over fill with a couple qts of diesel and run at a fast idlle for 20 minutes trick.
