Shell Rotella T1 Single-Grade 40W Diesel Engine Oil – 5L | Part #550054467
Rotella T1 is Shell’s single-grade diesel engine oil, formulated for older diesel engines and applications where a straight-weight oil is specified. The 40W grade flows easily at operating temperature and delivers consistent protection in diesel powerplants that run in warmer climates or controlled-temperature environments. Sold in cases of 3 × 5L bottles.
Key Features
- Single-grade 40W formulation — designed for diesel engines specifying a straight-weight oil rather than a multi-grade
- Low ash content — minimizes deposit formation and helps keep intake ports clean over time
- Outstanding oxidation resistance — helps extend oil service life and maintain performance between changes
- Rust and corrosion protection — guards internal engine components against moisture and corrosive byproducts
- Optimized dispersants — helps prevent sludge and varnish buildup inside the engine
Specifications
- Grade: SAE 40W (single grade)
- Application: Diesel engines
- Size: 5 litres per bottle
- Case pack: 3 bottles per case
- Part number: 550054467
Parts Desk Insights
Best use case: Rotella T1 40W is the right choice for older diesel engines — particularly stationary, industrial, or vintage marine diesel applications — that were designed around straight-weight oils and may not be compatible with modern multi-grade formulations. It’s also a practical option for warm-climate diesel use where cold-start viscosity is not a concern. If your engine calls for a multi-grade heavy-duty diesel oil instead, the Shell Rotella T4 Triple Protection 15W40, 5L is the most comparable modern alternative in the same bottle size. For the same T1 oil in a 30W grade, see Shell Rotella T1 30W, 5L – 550054460. For high-volume diesel service, the Shell Rotella T4 Triple Protection 208L Drum is available for bulk dispensing.
Note: This product is sold in cases of 3 × 5L bottles. Always confirm your engine’s oil specification before ordering — single-grade oils are not interchangeable with multi-grade specifications in all applications.
