Shell Rimula R5 LE 10W-40

Worth knowing

This one can brings together ACEA classes from different ash branches: E7, for which the current ACEA system allows up to 2.0 % sulphated ash, and E11, with a ceiling of 1.0 %. The data sheet gives exactly 1 %, so the figure sits right at the limit of the low-ash class. The third class in the list, E9, has given way to E11 in newer editions of ACEA, yet it remains in the name of an Iveco standard: the Iveco 18-1804 TLS E9 approval carries exactly this class, and TLS CK4 carries the API class.

Of the two Rimula R5 LE viscosities, only 10W-40 holds both Iveco approvals. Under the Iveco 18-1804 TLS E9 code, the catalogue lists just three oils, and this is the only one with an official Iveco approval. The 10W-40 alone also claims CNH MAT 3521, though without an official approval. The 10W-30 does without these codes but has DAF PSQL 2.1E, which this oil lacks. The rest of the list, from API CK-4 to Volvo VDS-4.5, is the same for both oils.
