Re: Marine Lubrication
Perhaps Amsoils best automobile oil:
Series 3000 Synthetic 5W-30 Heavy Duty Oil
Long service life oil engineered for both diesel and gasoline engines including turbo charged vehicles. Provides superior wear protection and fuel efficiency compared to conventional oils. Premium synthetic oils and additives with 12 TBN chemistry resists oil breakdown from heat, blow-by chemicals, acids and oxygen. Improves cold temperature starting. Global performance specifications include: API CI-4+/SL/CF, EO-N + 03', DHD-1, ECF-1, ACEA A3/B3/E3/E5, VDS-3

Re: Marine Lubrication
Amsoil Marine gear lube. I was told it is guaranteed to protect in drives with as much as 10% water contamination and that included rust and corrosion. Amsoil usually lives up to it's warranty with repair dollars if need be I have been told.
Excellent Gear and Bearing Protection even when contaminated with 10% water
Reduced Friction and Wear
Rust and Corrosion Protection
Long Seal Life
Superior Foam Prevention
Their site now posts data with and without water contamination. The data is compelling...so long as you catch the problem before exceeding 10%.

Re: Marine Lubrication
I was asked for the link to Volvo Penta Synthetic Marine Oil.

Re: Marine Lubrication
I was asked what oil has as much or more ZDDP than Mobil-1 V-Twin.
I have not found one yet.

Re: Marine Lubrication
This place offers some great prices on Redline..Redline claims to be superior to PAO's...that's always been up to debate and it just keeps going...
$7.00/qt for many...great price for gearlube as well.

Here are the 3 best reason to consider an ester based oil:

Now under perfect conditions this type of lubrication will not allow wear. But in reality,
this is not always the case.This takes us to the next state of lubrication.
MIXED FILM LUBRICATION
This is where lubrication is marginal. Under load conditions oil is squeezed under pressure. For example, during accelleration of an engine, you step on the gas and the engine dumps fuel, in turn the force is increased against the rod bearings, pushing (or squeezing) on the hydrodynamic oil creating a marginal lubrication condition. This is under normal use. But what happens to oil when it is under extreme pressure created by abuse or just a heavy foot? Follow me to the next state of lubrication.
BOUNDARY LUBRICATION
This is where lubrication is dependant on antiwear additives. What happens here, is lubrication can be put under so much pressure, and is momentarily squeezed out to such a point that if oil didn't have any antiwear additives, you would be metal to metal. This is the last line of defense for lubrication to protect your equipment. A common place where you see a lot of high levels of barrier lubricant is in gear lubes. Ever wonder what that rotten smell was? Yep, high levels of zinc, and phosphorus. These are the two most used antiwear wear additives used in oils today.
A lot of aftermarket additives use zinc and phosphorus for extra protection. The problem is, when you overload an oil with this type of additive, your oxidation levels tend to increase, causing an attack on the base oil, which in turn can cause an increase of viscosity, (thicken the oil) .This is why it is important not to play home chemist and blend in aftermarket additives that are not designed to be in the oil to start with.
So, as you can see, viscosity of the oil isn't the only important factor. Like building a house, you want a good foundation or base. Then you would use a quality product to build with. In this case, a good base oil is a start, then with good additives you achieve a good lubricant. Is zinc and phosphorus the only barrier additives available? No, there are more. Follow me to a barrier lubricant that has been around for a long time and has proven out for many years..

Did you get this from the "Basic Fundamentals of Lubrication" Your posts seem to go along the line with that book.

I quoted what you wrote. I am asking if you got that out of that book. A few of your posts look like the came out of that book verbatim
