Generally speaking, multi-grade motor oils or automatic transmission fluids are used.

Phillips was among the first oil companies to introduce a multi-grade motor oil, TropArtic, in 1954.

The brand now includes multi-grade motor oils, oil filters, synthetic grease, transmission fluids, and gear lubricants.

These additives are used to make the oil a multi-grade motor oil, though it is possible to have a multi-grade oil without the use of VIIs.
