Shell RotellaT1 40 CFSL 6*1 QT CASE

Shell Rotella® T1 Energized Protection™ oils use well-proven performance additives to fight engine wear and prevent deposits, providing reliable lubrication and consistent performance. Suitable for day to day use in turbo and non-turbocharged older engines.

• Conventional (mineral-based) heavy-duty diesel engine oil
• Monograde SAE 40 oil (single viscosity)
• Designed for older diesel engines and steady operating conditions

Product Classification

• Type: Heavy-Duty Engine Oil (HDEO)
• Base Oil: Mineral / Conventional
• Viscosity Grade: SAE 40 (straight grade)
• API Rating:
  • CF (diesel engines)
  • SL (gasoline engines – limited compatibility)

Applications

Recommended for:

• Older diesel engines (turbo & non-turbo)
• Construction, mining, and agricultural equipment
• Mixed fleets (diesel + some gasoline engines)
• Detroit Diesel 2-stroke engines (Series 53, 71, 92)
• Some hydraulic and transmission systems (if SAE 40 required)

Performance Characteristics

• Best for warm climates / high-temperature operation
• Not ideal for cold starts (since it is monograde)
• Provides stable viscosity at operating temperature
