What Lower Unit Oil Are Ya'll Running?

[Hydrasports205]

Just picked up a new lower and wanted to see what everybody thinks is the best stuff to put in it.

You'll get a bunch of different opinions, but I like the Merc high perf gear oil. (they sell two types)

I'm running the hi-perf Merc stuff rite now too.
I like this and Royal Purple Max-Gear.
My little 115 will spin around 200 rpm more with either of these than with "regular"/non hi-perf gear lubes.
Gives me a few RPM really cheap.

I like the Allisyn "O" weight in the race boats and Pennzoil 100 % syn in the lake boats.........

I thank Merk performance stuff iz good az any...Doing what U will be doing...I do like the royal purple geer oil, bit it juss ain't az eazy to git around here az merc stuff..REX

Im running Merc High Performance Lube in mine because Im having problems with water getting in. When they have to go in for repair I dont want any questions.
I would like to use Redline.

[Hot Shot Merc]

Works great but you have to change it often.Makes the prop spin real easy :eek: :D

[Ted Stryker]

I use Pennzoil Synthetic because of price and availability, but Redline is probably as good or better than any... I also have heard of some Hi-Po guys using synthetic ATF, I just haven't been brave enough to try it yet.... I'm strictly a Lake Boat/River Racer sorta guy....

[kingsbiship]

Premium oil for a cheap price and you can buy it anywhere!
