So far this season they have not lost 1 drop in 32hrs, and the oil is still clean enough to see thru.
I also put M1 75-90 in the drives which I'm going to change just to check for metal on the plugs.

I am interested to know your experience with Mobil-1 gear lube as some members have used it with much success.

If you mix in straight 40, does it have to be Mobil 1 synthetic? Here is the question. Is it better to mix in a lighter weight synthetic than the same or close weight non-synthetic?

From the little I know about "mixing" and producing a synthetic blend..my understanding is that usually a straight weight conventional is the base that the synthetic is added to..why I don't know.
If I were to play with Mobil-1 20W-50 V-twin and add a conventional product in a 50/50 mix I would use 40wt Kendall.
Same with the 15W-50 M-1. Something "inbetween" as the base in viscosity...not the "max".
I do not exactly know what you will wind up with but I would bet it would be a good blend and perform well.
...so when ya gonna do it?

Re: Marine Lubrication
Okay guys...Mobil-1 15W-50 is no longer being offered by Wallyland at this time in quarts or bulk containers...'cept for the leftover stuff..why? .. who knows.
They do now carry Castrol Syntec Fully Synthetic Oil in the 20W-50 weight...black bottles.... darn good stuff and it specs out with the best 20W-50 synthetics as well.
Price...$5.56/qt in quart bottles only.
Great stuff...great price...

Hydro, If my motor has always had the Mobil 1 15w-50, is it ok to switch to the Castrol?

...however...the isomerization process they use makes it about as tough as many Group IV bases as seen in comparison to conventional oils and synthetics.
As we know there are many grades of Group IV bases. Amsoil has several for many viscosities and some border on Group III...while the Series 2000 and 3000 products border on Group V formulations.
FYI...the recent reformulation of V-Twin shows it is a Group IV with no ester Group V's. It still specs out the same.
The only true Group V. is Redline as far as I know...it's like $11/qt.
Why the reformulations? You tell me..
Castrol 20W-50 "synthetic"is a real good product..excellent additives...M-1 has the edge of course..
