Post by 90chevy396 » Sun Apr 06, 2014 4:31 pm

just picked up a 455 dd boat and owner used sae 40 but I would prefer amsoil 20w50. just trying to get an opinion on what everybody has been running and what intervals direct drive guys run on their oil. first time owning airboat but have run a couple over the years. looking for any input from guys with experience

decided to go with vr-1 race oil for the zinc and available most anywhere. I have an account with amsoil and can get the z-rod oil for it but has to be ordered for the following day for about $2 more per quart. price wasn't a real concern just that the previous owner has very little hours on fresh rebuild of engine with lots of upgraded parts and he prefers Valvoline. thanks for any and all input guys. new to the sport and after owning mud trucks for most my life appears there is still a good crowd in airboating

Yep, I do use 4 quarts of Rotella T with a quart of Lucas oil additive.
