Up here in QLD the local Ampol (Caltex) and Costco have additive cleaners. No need to add extra and let's be honest not likely needed in Australia.Interesting he’s a fan of diesel additives.
I’ve always used one and add it every second or third tank out of habit, but so many people say it’s a waste of money as they add it to fuel these days.
