The oil had "burned off" all its light ends but was still lubricating the engine. There was no engine damage.
Why would a person who has 10's of thousands of dollars tied up in a toy, try to "save " money by purchasing the cheapest lubricant possible. Buy the better oil and buy one less beer at the bar. Ken

Now that we have "seen" the stuff works it justifies the added price. I started all this a year and a half ago to get some products used and to see what works BEST. I found my answer.
I also realize that Amsoil has several great products and that Kendall 20W-50 is well respected and should be. Shell Rotella 15W-40 is the way to go for a great conventional formulation that is nicely priced.
I do not want to appear to be the "end all" of what you should and should not use. But you guys have kept me in line from time to time when I got a bit over-zealous with my preferences. Lots of great choices...but very few BEST POSSIBLE contenders. The Premium Synthetics rule and they should due to cost...but they are worth every drop in my opinion. It is not marketing BS it is fact on both paper and in the crankcase they add a bigger margin of saftey and protection. These products are not ripoffs...they work.

Re: Marine Lubrication
New Amsoil Oil Filters looking quite impressive...who is going to give 'em a try for us?
http://www.amsoil.com/products/ea_filters/EaO.aspx
Benefits include:
• 25,000 miles or one year service life in cars and light trucks
• Higher capacity than competing filter lines
• Excellent flow characteristics
• Reduced engine wear
• Certified OEM fitment
The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting premium grade silicone anti-drain valve.
Fast Fact: A nanofiber is less than one micron in diameter. A human hair is 80 microns.
Nanofiber Filter Media
Traps sub-micron size particles on the nanofiber surface
Prevents particles from lodging in the filter media depth

Re: Marine Lubrication
Just noticed Amsoil is phasing out the SDF's and replacing them with these new Ae filters. I think I still have a few left for the boat and my wifes car so I guess I'll be going through them first.

Oil overheating is probably responsible for more engine failures than most realize. It decomposes the oil and you are left with little film strength.
Remember...keep your oil cool...probably the best lesson we seemed to have picked up on this year.

Re: Marine Lubrication
I was asked what is the lowest viscosity Synthetic oil that I would consider trying out in a stock offshore rig....my best guess would be M-1 10W-40 Synthetic Motorcycle oil. It probably would be just fine and you would get better immediate flow and great cooling too. I would not use it for racing or in hopped up mills. But for 496's or Small blocks why not as it has a flashpoint of 487*F...tough stuff...! It has lots of ZDDP like it's big brother V-Twin.
15W-40 Amsoil would be worth a look see too.

Re: Marine Lubrication
I got a couple more e-mails asking if there is a "SAE 30 WT" synthetic...this is the closest thing I can find...up to you as to deciding if you want to go with it.

Re: Marine Lubrication
Should you fog before storage?..yes...with what? a product such as Merc's fogging oil..
A side advantage to fogging some have found is the hard carbon gets softened by the oil when sitting for a few months. Noticed this visiting a shop doing preseason rebuilds, the carbon comes off "ez" if the engine had been fogged.
Probably some gets blown off after the first good run too.
