Hi Guys,

I suspect your supposed stripped off galvanizing inside your truck fuel tank is more likely to be cleaned off gunge from years of petro diesel. Vehicle fuel tanks which are actually made from metal are generally zincanneal (electroplated zinc, as opposed to hot dipped into zinc as for galvanizing). I have been using B100 in three of our vehicles for years (47,000k's in the Cressida diesel over a 19 month period with not even so much as a fuel filter change in that time, and about 60,000k's in the coaster bus with only one change of fuel filter about 500km from when I started using bio). Bio is a great cleaner, especially if the fuel is processed but not washed to clear it of excess caustic soda.

Have a good day.
