In my '79 Ski Nautique 351W I use Castrol GTX 10W-30, owners manual recommends 10W-30 or straight 30W
In my '02 Ski Nautique with the PCM Excalibur (350 Chevy) I use Castrol 15W-40 as recommended in the manual. 15W-40 is most commonly used as a heavy duty oil in diesel engines but it's rated for spark ignited engines as well. |

Castrol- as it contains no parafin which will cause sludge. Weight and other ratings as determined by OEM.
