20W50 Mineral Classic Motor Oil - High ZDDP
Superior Protection for Vintage & Classic Engines
This 20W-50 Mineral Classic Motor Oil is a high-performance lubricant specifically engineered for engines built before 1980. Unlike modern low-viscosity oils, this mineral blend provides the thick protective film required by older tolerances and high-mileage units. It is enriched with high levels of **Zinc Dialkyldithiophosphate (ZDDP)**, approximately 1250ppm, to safeguard critical internal components from metal-to-metal contact.
Key Benefits
- ✔ High ZDDP (Zinc) content for anti-wear
- ✔ Excellent oil pressure maintenance
- ✔ Prevents sludge and carbon build-up
- ✔ Safe for cork, paper, and fabric gaskets

Questions & Answers
Is this oil suitable for modern cars with catalytic converters?
No. The high level of ZDDP (Zinc and Phosphorus) can damage modern emission control systems. This oil is strictly intended for classic, vintage, and high-performance pre-catalyst vehicles.
Why is "High ZDDP" important for my classic car?
Older engine designs often use flat-tappet camshafts. Modern oils have reduced zinc to protect catalytic converters, which can lead to rapid cam wear in older engines. This formula restores those essential anti-wear additives.
Can I use this for both Petrol and Diesel classic engines?
Yes, this oil meets API SF (Petrol) and API CC (Diesel) specifications, making it versatile for a wide range of pre-1980 automotive applications.
Note: Always check your vehicle manufacturer's handbook for specific viscosity requirements and service intervals. For use in classic engines only.
