Which brand of diesel?

[Transporter]

Thanks for that - just went to see if what is in the shed was CRD specific - chemtec has no mention CRD on the bottle.

Many incl. me wouldn't use Chemtec Diesel additive, Chemtec makes some great products, I use theirs CT18 Truck wash and Glass cleaner but their Diesel additive is not a good one (at least IMO).
