Volvo penta engine oil and out drive oil

[robert s75]

I have a 2008 5.0 L GL Volvo Penta, and need to change oil and out drive oil. I have had all mercruisers in the past, so I would like to know what you would recommend using. The out drive is a SX-A.

what does your manual tell you to use?

 

[BRICH1260]

I use Mobil 1 synthetic 15-50w for my engine and Amsoil 75-90 synthetic GL5 for my drive. Engine oils have improved in the last nine years. mine called for straight 30W, I feel the synthetic 15-50 is superior now to what was called for back in `08. What ever brand drive oil you choose, make sure it is GL5 rated, something to do with the clutches.

My 5.0 GL and SX-M calls for:
VP's Synthetic gear oil and 15w/40 SAE

I don't have a manual boat didn't come with one, I did ask though. Thanks for the help, I'm having my trim cylinders rebuilt now, looking forward to getting all done and on the lake.

Like BRICH1260, I also used Amsoil 76-90 synthetic GL5. I did a lot of online research before I finally settled on that oil. There are others choices out there as well.

I have been warned away from any oils with Limited Slip additives. Most shelf GL5 rated oils are now including limited slip additives. Supposedly its not good for the cone clutch

Your outdrive calls for 15w/40?

That is the same information that I found in my research. It eliminates most of the gear oils that one can buy in the auto parts stores.

Amsoil marine gear lube does not have the Limited Slip LS additives in it. Amsoil made the Volvo brand oil a few years ago, I do not know who makes it now.

No, that's the engine oil. The drive takes the VP synthetic gear oil, Sorry I should have switched the order.
