Shell Rotella T1 Single-Grade 30W Diesel Engine Oil – 5L | Part #550054460
Rotella T1 30W is a single-grade mineral diesel engine oil designed for diesel engines that specify a straight 30W oil. It delivers consistent lubrication and wear protection in applications where a multi-grade oil is not required or recommended — particularly older diesel engines, stationary power units, and equipment operating in moderate to warm ambient temperatures. Sold in cases of 3 × 5L bottles.
Key Features
- Single-grade 30W formulation — for diesel engines specifying a straight-weight 30W 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 combustion byproducts
- Optimized dispersants — helps prevent sludge and varnish buildup inside the engine
Specifications
- Grade: SAE 30W (single grade)
- Application: Diesel engines
- Size: 5 litres per bottle
- Case pack: 3 bottles per case
- Part number: 550054460
Parts Desk Insights
Best use case: Rotella T1 30W is the right choice for older diesel engines — vintage marine inboards, stationary generators, and legacy commercial equipment — that were engineered around straight-weight 30W oil and may not be suited to modern multi-grade formulations. It’s also used in warm-climate applications where cold-start viscosity is not a concern and the OEM spec explicitly calls for SAE 30. If your engine requires a 40W single-grade instead, see the Shell Rotella T1 40W, 5L – 550054467. For year-round or cold-climate diesel use, the Shell Rotella T4 Triple Protection 15W40, 5L is the multi-grade alternative in the same bottle size. 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.
