Oil question

[Cast-A-Way]

I am changing the oil in my 4.3 omc this weekend and was wondering the only oil I seem to find in the sae 30 says diesel oil is that normal ?

Or what would the best oil be ?

Thank you

Re: Oil question

Yes, you need to use straight 30 weight.

Thank you danond

I did an oil change a couple of weekends ago with 10-30 and I find the pressure too high
So after the advice from the site I started looking for straight 30 weight oil and all I found said diesel but on the back of the jug said it could be used in gas and propane engines

Thank you I now know that it's ok to use
