Gulf Formula RNX 5w-30 Fully Synthetic Engine Oil

Gulf Formula RNX is synthetic, catalyst compatible passenger car motor oil specially designed using most modern additive chemistry meeting Low SAPS (Sulphated Ash, Phosphorous & Sulphur) requirements for vehicles meeting Euro IV norms. 

It has been exclusively developed for use in high performance gasoline and diesel engines requiring low SAPS oil with HTHS greater than 3.5mPa.s in passenger cars and light vans fitted with Diesel Particulate Filter (DPF) and Three Way Catalyst (TWC) to extend life and maintain efficiency of these after treatment devices. 

It provides exceptional wear protection and minimizes deposits in engine and turbocharger. It is developed to exceed the service fill requirements of most recent models of Renault and other OEMs requiring ACEA C4 type of oils.
