Hello.... I was getting ready to do an oil change on my VDrive unit and noticed a discrepancy. This summer I bought a '12 Mobius LSV and intend on doing the maintenance/service/winterization myself. I used to do my previous I/O and consider myself pretty decent with a wrench.

However when I went to begin with SAE #30 oil...I noticed this sticker directly in my VDrive unit placed from the moomba/ or indmar factory.



So I stopped and decided to dig further.

Both my Moomba manual





And my Walters VDrive manual



Indicate that I should use SAE #30 oil

I'm positive I have a Walters VDrive model RV 26D




Soooo what do you guys think? .... I'm leaning toward SAE 30 oil but can't figure out why molmba/indmar put this sticker on my VDrive unit that says to use 15W40... What do you guys think?
