I use Honda HP4 10W-40 in all of my Honda motors, vintage and modern. It provides more than enough shock protection, works well for the clutch and is relatively inexpensive. What more can you ask for? dogger |

You can go with the engine oil suggestion or straight SAE 80 weight gear oil. I have used both Bel-Ray and Maxima. It is far more important to change it regularly than fret over the brand. |
