This premium mineral engine oil is a smart choice for petrol and diesel passenger cars, 4x4s and light commercials that call for a 15W-40 grade. It holds its viscosity when things get hot-think heavy loads, summer heat or stop-start traffic-so a strong oil film keeps critical parts protected. Fast flow on cold starts gets lubrication where it’s needed in those first few seconds, helping reduce wear from the get-go. It’s catalytic-converter safe, so you can top up with confidence in modern emissions-equipped vehicles. Behind the scenes, powerful detergents clean as you drive, sweeping away deposits and helping to stop sludge before it starts. Anti-wear additives shield cams, lifters and turbo bearings, while oxidation inhibitors slow oil breakdown to keep performance stable right through to your next recommended service. That means a smoother-running, cleaner engine and peace of mind between drain intervals. Running in a fresh build or reconditioned motor? X-Protect’s balanced mineral formulation is also suitable as a running-in oil, giving rings a proper chance to bed while still protecting vital surfaces. Reliable, practical and great value for everyday motoring.
