When adding Sea Foam to my VW Jetta 2.0T fuel tank, someone told be it’s best to add when the fuel is close to empty. So is it better to add a whole can of Sea Foam to a low fuel tank and then fill up? Or, should I do some driving before adding more fuel?
That’s a great question Chris. If you add when the tank is low you’re able to increase the cleaning concentration. If you’re able to drive at least 20 miles before adding fuel you’re able work the higher concentration through your Volkswagon’s injectors and upper engine. Just don’t put yourself in a situation where you’re at risk of running out of fuel.
