Is now a good time to upgrade to new engine oil specifications for your vehicle?
Shell Rotella is updating its heavy-duty engine oil portfolio to meet new API CL-4 and FB-4 specifications starting in early 2027. Owners of diesel trucks will see enhanced protection and significantly extended warranty coverage for T5 and T6 synthetic products.
Why it matters
These new formulations are engineered to better support modern emissions systems while increasing protection against engine wear and oil breakdown. The shift allows truck owners to rely on longer protection intervals for their vehicles' maintenance needs.
The new lineup includes upgrades like a 15-year or 600,000-mile warranty for T6 oils and a 12-year or 400,000-mile warranty for T5 products. T5 10W-30 oils now exceed standard oil breakdown requirements by over 90%.
The players

The details
The updated oils utilize advanced additive systems designed to improve the durability of Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCR) systems. Formulations were validated through extensive fleet trials and laboratory evaluations to ensure they meet the new industry licensing standards.
