We just purchased $8000 worth of products from Wurth. I asked the reps (re the engine flush) was it solvent based or detergent based.
They couldn't tell me!!! as apparently its new in OZ (according to them).
All they could tell me was that alot of Wynns customers had converted to the Wurth product. Maybe sales pitch???? but they are getting back to us ASAP. Money talks - VBG
