To be honest I am not a fan of additives.. I just use good quality fully synthetic oil in the right grade to suit the KLM of the engine and change it every 5000ks and a new oil filter at the same time.. I don't like coolant additives because they are a bandaid usually for a problem that needs to be fixed properly. I have also seen them cause a LOT more problems than they solve.. Gear oil tends to last a long time so I have never needed to mess with it. 98ron fuel has injector cleaning properties so I only add Inj Cleaner maybe once a year in our Subarus but ever 4 tanks I add a little to our 4wd diesel van as well as the occasional swig of petrol in the tank as well as a litre of canola oil every 12 months.. I did run a can of Upper cylinder/manifold cleaner in the Lib today before I gave it an oil and filter change.
