850 hours on engines. Note high sodium (Na), thin viscosity, and low flashpoint in both engines after 80 hours. No oil added.

Interesting, if it were mine I would ask blackstone if the low viscosity and low flash point is something to be concerned about. If it is it might be a good idea to reduce your oil change interval to something like 50 hours and check it at that interval.


Boy will I be happy when ALL vehicles on public roads are autonomous.

How are you running these engine? Lots of trolling? Does the engine get up to temp and stay there for a while?


2007.5 dodge cummins 6.7 liter. Chevron Delo400 15w40. 7000 mile or 250-300hr intervals.

Yes and yes. Lots of trolling (6-8 hours at a time). For this particular OCI, all trips included total of 100-200 miles at speed around 4000 rpms for hours on end to/from continental shelf.

This is recommended oil per manual.

Note: this is shortest OCI I've ever done on these engines.

I see mods moved this to the small engine forum.

jeeezzzzz

guys 1.0% fuel will totally kill the vis and flash. period.

look no further than 1% fuel

you are searching for something that does NOT exist.

fix the fuel and the flash n susvis will come back to expected values

sodium could be coming in via intake...hard to prevent on a salt water craft
all it takes it 1 ppm per hr of runtime. do you taste salt when you breath in? wink

Wow. What a massive slug of moly. Nice!

I would never run more than 50 hours on a hi-po outboard. Try sticking there. You might like it.

Latest UOA, from Oil Analyzers this time to get good fuel dilution values. Fuel dilution > 5%. Looks like need to shorten OCI, and run at WOT for a while to see if that helps

Looks good, wear metals are good, I mean that is what we want right?

I am curious, did you run the engines and oil up to full operating temperature when you took the sample for the UOA?

High performance direct injection marine engines are always going to have fuel in the oil until the oil gets piping hot and the fuel burns off/vaporizes, I would think, anyway, 2 different engines, same exact results, it wouldnt bother me and I would make sure oil was piping hot on next UOA and I would think, if you find another owner of the same exact engines, same temperature oil when taking the sample that person would have near the same results.

I am amazed at a 5/30 oil in a marine engine! My we have come a long way.

Thanks for your comments. Yes, took the sample after engines had been run for 8 hours straight, so everything was very hot. Fuel dilution didn't become a problem for these engines until about 700 hours, so I'm thinking (hoping!) they just have some carbon buildup due to all the extended idling and trolling that needs to be burned off.

You troll with a 300? I own a 90 Merc 4 stroke and wouldn't troll with it. Electric trolling motors or kicker motors were built for a reason.
Also, without reading this whole thread, have you tried anything other than Yamalube? Imo, Yamalube is way overpriced for what you get.
I'd try something different, which, in most cases, will likely be better and likely about half the price as well.

They aren't like an ILSAC 30 however.

The spec requires a post shear 3.3 HTHS.
