Review: Posseggo una vecchi Fiat topolino 1950 con motore ormai da rifare. Spesso l’auto funzionava a tre cilindri causa candela sporca di olio. Dopo l’uso di questo prodotto ora l’auto è più di un mese che non da problemi. Ovviamente parliamo di soluzione temporanea di cui beneficiare finché dura. Nulla di definitivo Review: Delivery was faster but I have to come back to review it again after using it. But it looks good. ## Features - Oil additive, additive. - - - Item number: 9990. - Mannol Motor Doctor additive raises the oil pressure and reduces the oil consumption in worn engines.
