Ultimate Metal Guard Engine revolutionises the protection and performance of your engine, unlocking hidden power, minimising fuel consumption and ensuring years of trouble-free operation – all verified in laboratories and on dynamometers.

Greater Power and Dynamism

Thanks to a 25% stronger oil film, the engine loses less energy to friction – you gain real power increases: up to 8 HP and 13 Nm in vans such as the Fiat Ducato, over 23 HP and 50 Nm in the Mercedes E250 CDI, or even 27 HP and 47 Nm in the AMG V8 sports car. This means smoother driving with a load, safer overtaking on the motorway and a sporty driving experience without interfering with the electronics – simply more power at the wheels every day.

Extreme Wear Protection

Forget about metal-on-metal friction: the formula creates a durable lubricating film that protects pistons, bearings and shafts even during cold starts or stop-start cycles. Withstands pressures up to 245 daN (vs 196 daN for pure oil), eliminates ‘sandpaper’ from rust and ash, which extends engine life by years, reduces operating temperature and prevents seizure – ideal for fleets, hybrids or city cars.

DPF Cleanliness and Safety

The only additive reducing sulphate ash to 0.70% (lower than the base oil!), Metal Guard protects DPF/GPF and EGR filters from clogging, prevents LSPI in petrol engines and removes damaging deposits from cylinders. You benefit from less frequent filter regeneration or replacement, no Check Engine errors and a clean combustion chamber – you save on servicing and enjoy eco-friendly, reliable performance.

Anti-corrosion and 24/7 Stability

In a salt spray test, it protects steel 70 times longer (18 hours vs 15 minutes), blocking acids and moisture whilst the engine is stationary. Viscosity remains at factory levels (11.10 cSt at 100°C), without thickening or thinning – the oil pump and turbocharger operate perfectly, even when mixed with fuel.

As a result, you save fuel (up to 10%), reduce repair costs and enjoy a quiet, responsive engine for thousands of kilometres – an investment that pays for itself from the very first journey.
