VOA Yamalube

VOA Yamaha Yamalube FC-W Synthetic 5W-30 (marine oil - gold bottle)

 

[Popsy]

Thank you for the VOA. Looks pretty decent, but overall low TBN for a marine lube?

Looks like the cheapest oil they could find with a good dose of moly.

Good eye Popsy - another reason I dropped this oil for RP HPM - it has 10.1 and is NMMA certified ...

 

[Popsy]

Apart that, good dose of Moly + Boron

A "dated" formulation maybe?

My Yamaha specs 5w30 or 10w30 FCW ... I also wanted a 10w30 synthetic and that led me to RP HPM.

Yamaha has more tolerance for VII. Compare that to Merc 25W40 - they don't want VII ...
(Maybe its the racing side of Merc pushing that) ...

 

[Bluestream]

SO what qualifies it to be FCW?

 

[Chris142]

So much for moly and wet clutches.

 

[MolaKule]

The statement about iron being uncommon is incorrect and has nothing to do with storage drums.

Metal deactivators and rust preventive additives (part of the additive package) cause this reading.

 

[claluja]

Thanks. Makes sense having seen similar Fe content in VOAs of othwr oils. Any thoughts on whether this oil would be better for gas outboard marine engines, than say T6?

 

[MolaKule]

Dupe

 

[MolaKule]

I would think that the Yamalube would have extra metal deactivators and rust preventive additives to deal with the humid environment.

Looks like a Redline oil, with loads of Moly and more normal Boron and Zinc. Near the top end of the SAE range. Not enough Ca for a diesel, so it looks more like a Bike oil in several ways, apart from the excessive Mo.

Can't understand why Blackstone commented on the Iron, as 1 ppm is not the end of the world!

Yamaha sells two oils for the 4 stroke outboard - this one and the 4M 10w30 Dino ...
