04 LSV "V" DRIVE OIL

[seanpatsdad]

What are most putting in the "V" drive transmission for oil.Brand and grade is what I am looking for.Thanks for any help and Happy New Year.

The Walters V-drive uses SAE 30 only, Indmar reccomends Pennzoil, but if not available, a good name brand oil will suffice. The Hurth transmission uses Dexron III trans. fluid. Brian Raymond

Thanks Brian.That is the motor oil and not some kind of hydraulic fluid?Also is that just a splash lubricant or is there a pump in there?Just curious.Can't wait to get back on the water.Close to 50 in Indy again today so my mind is on the boat and not snow.Thanks again.

I use synthetic. I'm sure it does not hurt.

What brand and grade are you using for synthetic.Thanks for any info.

SAE 30 - of whatever the dealer uses. From the net:

The benefits for synthetic motor oils include:
• Better low temperature viscosity performance.
• Better high temperature viscosity performance.
• Decreased evaporative loss
• Reduced friction
• Reduced engine wear
• Improved fuel efficiency
• Chemical stability
• Resistance to oil sludge problems
• Some synthetic motor oil producers offer extended drain intervals
The disadvantages of synthetic motor oils include:
• Initial cost
• Potential oil seal problems - if the oil does not contain sufficient seal conditioners.
• Potential decomposition problems in certain chemical environments
• Potential stress cracking of plastic componentry like POM (polyoxymethylene) in the presence of PAO's.
Initial cost may be mitigated by extended change intervals, but those need to be confirmed by oil analysis for each particular user.


I do not worry too much about who makes the oil, there are really only about 5 guys to pick from and none have a documented edge over the other. At least not documentation I trust.

I do believe synthetic helps engine wear and I have no doubt i work the engine hard in the summer.

Oh, if you go synthetic, going back to regular can causes seal problems.

My thing is that I can't find a straight 30 wt synthetic.Most are 5w-30.Thanks for the replys.

yea, I think it is 5w,

The biggest difference between a multigrade and a single grade is that the multigrade must not become too viscous at low temperatures, while still meeting the requirements of its high temperature grade - in other words, multigrades exhibit less viscosity change with temperature than most single grades.

Thus, a typical 5W-30 motor oil has the same approximate kinematic viscosity as a SAE 30 grade oil at 100 ° C, but it's viscosity at very low temperatures, while thicker than when hot, is much less than the 30 grade. This is achieved by formulating multigrades with a higher Viscosity Index than typical for single grades.

More than you ever wanted to know

If you run in winter use multigrade.

Thanks for the help.
