Motul Classic Eighties 10W-40 Semi-Synthetic Engine Oil | Case of 10x 2L (20L Total) | For 1970s–1990s Modern Classic & Youngtimer Vehicles

This listing is sold as a case of 10x 2L bottles (20 litres total).

Motul Classic Eighties 10W-40 is a semi-synthetic multigrade engine oil specially designed for Modern Classic and Youngtimer vehicles from the 1970s, 1980s, and 1990s — fitted with 4-stroke gasoline or diesel engines, naturally aspirated, supercharged or turbocharged, injection or carburettor. Engineered to meet the lubrication requirements of the engines from these decades — engines that predate the low-viscosity, low-SAPS oil specifications of modern vehicles and require a higher-viscosity, higher-additive oil formulation for correct protection. Motul is one of the most respected lubricant brands in the world — a French manufacturer with over 160 years of experience in lubricant development and a strong motorsport heritage across endurance racing, rally, and motorcycle competition.

Key Features:

• Semi-synthetic formulation — semi-synthetic base oil with a performance additive package — improved protection and thermal stability compared to mineral oil, at a price point appropriate for regular oil change intervals on classic vehicles
• 10W-40 viscosity — correct viscosity grade for the majority of 1970s–1990s gasoline and diesel engines — adequate cold-start flow at 10W and correct high-temperature viscosity at 40 weight
• Modern Classic & Youngtimer specific — formulated for the lubrication requirements of engines from the 1970s, 1980s, and 1990s — correct additive chemistry for older engine designs including higher zinc (ZDDP) content for flat-tappet camshaft protection
• Gasoline and diesel compatible — correct for both gasoline and diesel 4-stroke engines from these decades
• Naturally aspirated, supercharged, and turbocharged — correct for all induction types from the 1970s–1990s era
• Injection and carburettor compatible — correct for both fuel injection and carburettor-equipped engines
• Motul quality — manufactured by Motul, one of the most respected lubricant brands in the world with over 160 years of experience

Why Classic Vehicles Need a Specific Oil:

Modern engine oils are formulated for modern engines — they use low-viscosity grades (0W-20, 5W-30) and low-SAPS (Sulphated Ash, Phosphorus, Sulphur) additive packages designed for modern catalytic converters and DPFs. These modern oil specifications are not correct for 1970s–1990s engines for two key reasons:

• Viscosity: Older engines with wider manufacturing tolerances require higher-viscosity oils to maintain correct oil film thickness at bearing surfaces. Modern low-viscosity oils may not provide adequate film thickness in older engines.
• ZDDP (Zinc Dialkyldithiophosphate): Older engines with flat-tappet camshafts rely on ZDDP in the oil for anti-wear protection at the cam lobe/follower interface. Modern low-SAPS oils have reduced ZDDP content to protect catalytic converters — insufficient for flat-tappet camshaft protection. Motul Classic Eighties maintains the correct ZDDP level for older engine designs.
