Hello,
I just came across an empty 8 oz. bottle of "Startron Enzyme Fuel Treatment" for Diesels In my trunk. I think it has been awhile since I've used this.
How often should/can One add this to the tank?....I have
a 1983 300D.
I have also used "Power Service Diesel Kleen Fuel Additive" in the past as well.
Are either of these additives superior to the other?...or are they
both good products..
Thank you!
