Review on 🚗 Car Accessories by Matthew Hall

: VV633. The product supplied is VV615, optionally with a white Paper label (B. from a home printer) is pasted over VV633 I called Valvoline They explained that molybdenum is not as important as it was a few years ago but still confirmed: VV633 (advertised/described/listed) IS moly enriched .VV615 (included) is NOT moly enriched. Also, they said that Valvoline would NOT just add a sticker/tag with a different product number. What I received could be good, but I sent it back on principle ( see above and photos ).
