So not for your family vehicle...but marine use? Looking good after looking into it more...
They are probably the best of the lower priced oils. Rotella goes for 6 bucks at Home Depot in 5 qt plastic containers. With a $2.99 A/C filter it's the best value out there if you want to pay less...and some do.
Not to worry my synthetic friends....you guys have much tougher film strength and outperform all those other guys..

Lot's of great reading here, Thanks
I was already a BIG fan of Mobil 1 Syn oils. 95 Yukon with 185K miles all on Mobil 1 10w30 and the Z06 gets 5w30. Previous boat had Mobil 1 as well.

To add to everyone's confusion. The Mobilube SHC series is gone now. It's not Delvac Synthetic Gear Oil for the 75w90 and the 80w140. Also Superflo is gone, cases are still aviliable in stores. Also the Mobiltrans SHC 50 will be renamed..
Also one more wrench into your fire. The PVL/TRUCK/SUV oils have changed again... Here's the letter going to customers..
ENJOY!!

Re: Marine Lubrication
Hydro,heres a question from us northern guys:What is a good weight of synthetic oil to run in a snowmobile chain case? I don't buy off on getting little 6 oz bottles for 7-10$ from klotz or a oem,its obviously not some magical oil,it looks like 40 or 50 wt motor oil but I'm not sure. Its just lubricating steel sprockets spinning with a chain on them and has to lubricate down to about -20 degrees f. There are guys running 80/90 synthetic but I think it robs hp in the cold. On a side note I ended up with 55 gallons of synthetic quaker state 50wt gear oil that is about useless for anything,would it be a good candidate for these chaincases? Any opinions or experience on what oil would be about the best without getting ripped off buying these little bottles of "mystery oil" (I have 5 sleds to fill chain cases on),Smitty

V-Twin has the same silicon level as the HDEO's. And the ONLY HDEO that uses high levels of magnesium is MOBIL DELVAC 1. Rotella and Delo both have very low levels of Magnesium. So what exactly are these "harsher detergents"?

Smitty;
I have been running full synthetic tranny fluid in my snowmobile chaincase for 2 ears now. I got this from a couple of guys who have highly modified trail sleds. They usually put on 3000-4000 miles a year on a sled! If its good enough for my chain in my transfer case in my truck, I assume it is good enough for my sled. (lower viscosity less HP loss)

Silicon comes in many forms...some gets into oil from silicone seals...some in the oil itself and some from "dirt" that has the silica material like that found in sand. Some forms harsh and others not.
It can be a detergent...anti-foamant or "dirt" component. Depeding on molecular form.
Diesel oils do have more detergency and some say a bit more than that compatable to aluminum blocks. But they might be wrong...so I am fine with your comments.
So everybody is right on this one...I think.
