Reviews Extended Drain Intervals

Shell Rotella T5 Synthetic Blend 15W-40 Diesel Engine Oil (1 Gallon, Single Pack)

Synthetic blend 15W-40 diesel engine oil with Triple Protection Plus technology protects against wear, deposits, and oil breakdown.
Ideal for on-highway fleets, construction, and agricultural machinery, and diesel pickup trucks — including high-power vehicles that require resistance to heat and stress.
Improves low-temperature flow (compared to conventional 15W-40 oils).
Helps control engine deposits for reliability at extended oil drain intervals (always follow the OEM recommended oil drain interval).
Controls engine wear 37 percent better than the maximum wear requirements in API CK-4 engine wear tests.

✅ Minimized inventory cost by having one premium ATF that can be used for the vast majority of modern automatic transmissions on the road today,....
✅ Outstanding low temperature fluidity..
✅ Maximum equipment life with an advanced formula that protects against wear, corrosion, and the formation of lacquers, sludge or other harmful....
✅ Extended drain intervals because of improved oxidation resistance..
✅ Improved fuel economy relative to conventional fluids because of lower viscous drag..

Backward compatible with previous DEXRON automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous DEXRON fluids.
Improved performance over previous DEXRON fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance.
Potential to enable improved fuel economy and longer transmission life.
