Note: Some Chrysler, Volvo Penta and Yanmar units require engine oils. Yamaha HydraDrive units require GL-4 spec gear oil due to the copper in their clutch packs.

Exceptions are where a special oil or fluid is called for (particularly jet units), please check the Penrite Lube Guide for the correct product.
