Recommended Enigne Oil for Summer Temps

[LEE337]

I am getting close to firing the boat for the first time with the nytro motor. What weight oil should i be using for summer in this engine? I looked in the service manual but the range stops at 60 degrees F and only has 0W-30.

Any thoughts?

Thanks

most synthetic oils seem to cover a large operating temp range from other equipment I have looked at. If your cooling system can keep the engine at normal operating temps, I'd think you are fine running stock oil.

IMO there shouldn't be any difference in a motor running at 190* when it's 90* out or -40*

I need a picture of said boat to further evaluate what oil is needed. LOL

Check the 4 stroke sled garage for the full build thread.

5w30 should be enough. are you planning on monitoring oil temp to determine witch oil you should be using?

I do know there where some of the vector motors installed into ultralite's a few years ago but I do not remember if they mention what oil they where using.

I'd recommend a synthetic 40 weight.
