Hello Julie R, The STP diesel treatment goes in the fuel tank when you fill up. It should have the correct amount per tankful on the bottle. Be careful not to use too much as you don`t want to finish up with an over- concentration of treatment in the tank as this can damage non-metal components of the fuel system. Hope this helps. - Andrew

Can i put the diesel cleaner, dpf cleaner and injector cleaner in all at the same time?

Hi. I wouldn’t as the 3 are very similar. Depending of the issue you have use the one design for Fill your car with premium diesel then add the one you really need. I usually leave the car overnight and go for a Motorway drive. About 10 mins will do. You can add the others on a later date.

Would this be more beneficial if used with a regular full tank of diesel or a premium full tank of diesel

I’d only use premium diesel regardless what the car was. Cheaper diesel are the reasons why engines become blocked hence these products being created. I’d virtually empty the tank then put this in then premium then you’ll see the difference Hope this helps Thomas

How much do you put in the fuel tank

200ml treats 50/60 litres of diesel...so half the pack will treat a typical 25 litre diesel refuel.
