Description

Eni i-Sint XEF 0W-16 is a very low-viscosity synthetic engine oil from the i-Sint line for modern petrol engines in cars, crossovers and vans, turbocharged and hybrid units included.

The oil is rated API SP RC and ILSAC GF-6B; the maker lists no manufacturer approvals. Its formulation guards against low-speed pre-ignition (LSPI) and against timing chain wear.

Typical figures: kinematic viscosity 7.3 mm²/s at 100 °C, viscosity index 170, pour point -42 °C.

ILSAC GF-6B is not backward compatible with earlier ILSAC categories, so the oil should be used only where the vehicle maker explicitly calls for 0W-16.

Application

Modern petrol engines in cars, crossovers and vans, including turbocharged and hybrid units, where the vehicle maker specifies a 0W-16 oil to ILSAC GF-6B.

Worth knowing

The data sheet of this oil lists two classes, API SP RC and ILSAC GF-6B, and Eni explains the second one separately: GF-6B is defined only for 0W-16 viscosity. The transition period during which API allowed oils to be labelled with the GF-6 classes has ended, and for 0W-16 the place of GF-6B has been taken by GF-7B with the “shield” mark. The data sheet does not claim this newer class, so for an engine whose documentation specifically names GF-7B, this oil does not confirm compliance. How the “shield” differs from the “starburst” and what SQ and GF-7 added is explained in the article on what the new API SQ and ILSAC GF-7 classes mean.

There is no other 0W-16 among the i-Sint oils in the catalogue. The similarly named i-Sint XEF 0W-20 has a different viscosity grade (8.3 mm²/s at 100 °C against 7.3 mm²/s) and a different set of codes: ACEA C5 and C6, API SQ RC, ILSAC GF-7A, BMW Longlife-17 FE+ and MB 229.71 approvals, but no GF-6B. Whether an engine designed for 0W-16 will take another viscosity is for the owner’s manual to say, as the Eni data sheet itself notes.
