Engine Oil 20W50 Classic (5 litres)

Mineral engine oil for classic military vehicles

High-quality mineral engine oil SAE 20W50 specially developed for classic engines with flat tappets. This oil combines excellent protection at higher operating temperatures with reliable lubrication for older engine designs. Ideal for use in warmer climates and for vehicles regularly driven under load.

SAE 20W50

Type

Mineral oil

Contents

5 litres

Application

Classic petrol engines

Features

  • SAE 20W50 viscosity grade for warm climates
  • Suitable for engines with flat tappets
  • Protective additives for classic engine designs
  • Mineral base for older engine tolerances
  • 5-litre pack for multiple oil changes

★ This classic engine oil is tailored to the needs of older engine designs and provides reliable protection at normal to higher operating temperatures.

Application

Suitable for use in classic petrol engines at ambient temperatures above 0°C. The 20W50 viscosity is particularly suitable for warmer climates, summer months and vehicles driven under load. For colder conditions (below freezing), a lighter viscosity is recommended.

Compatibility

Note: For very cold climates (below 0°C), a lighter viscosity such as 10W30 or 15W40 is recommended for better cold-start properties. Consult your vehicle's technical manual for the recommended oil viscosity at different temperatures.

Historical context

The SAE 20W50 specification became popular in the 1960s and 1970s as a multi-grade oil for classic vehicles. This viscosity grade provides good protection at higher operating temperatures such as those found in older engine designs without modern cooling systems.
