Absolutely , low rpm & relative lower operating temperature under 300 f of outboards & to an extent LB mowers do not tolerate ash additives well ! Some purists advise zero ash within outboard actually , however some just recommend low ash . I run. a 4 stroke outboard now , so not still in the loop anymore .
Certified marine oils are all ashless IE zero ash.
 
I have enjoyed reading you and BWalker going back and forth on the steam issues and such. I can relate to some of it .I work at a paper mill that produces both parts of a cardboard box. At one time I run the dryers for one machine and now I moved up and run the wetend. Years ago we had a turbine driven line shaft that run the drives but have since upgraded to ac drives.Made life a lot simpler as for as maintenance ,runability, and safety. The turbine run on 850# steam and was not something to play with. One time someone forgot to remove the locking bar for LOTO ( 1x6x48” steel bar) before starting the turbine.Turbine didn’t even know it was there , bent it like a pretzel and kept on turning. Luckily no one was hurt but they scattered like a covey of quail.Be Safe!
Yeah , a lot of static & dynamic energy
 
I forgot to mention the line is also heat traced with steam tracing.
All of our pipe is insulated with Calsil insulation and jacket with tin. Control stations are cozy coated.
The oil branch line from the cargo line would require tracing to enable proper flow characteristics . Often within inside freeze proofing or smaller btu required heating applications the sensible heat of the condensate return system was utilized , quite often on metering station differential pressure applications . The latent heat of low pressure #15 steam was more often used on outside air line vent & dryer or drain stations or water line freeze protection requirements . We previously used silicate Johns Mannsville preformed insulation , however converted to Roxal mineral wool in 2000 . It was already used in numerous noise attenuation & R & K heat dissipation / absorption applications for Industrial mufflers & reusable turbine casing preformed blanket coverings . Reduced the labour intensity of r & r of insulation of various thickness's & layers on various prime movers during routine scheduled downtime & necessary equipment rebuilds . It also was condensate & water friendly in that it would only take on 2% per volume & quickly wick away any moisture it took on . Very good product utilized world wide today . I utilized it on my 1st base foot of insulation product of my new Welding shop . Above that I went with regular Owen's fiberglass accordingly .
 
I know you could run that Coastal oil daily without burning down your saw. We've all been brainwashed into thinking those conventional 2 smoke oils are no good anymore.
 
Scored 5 cases of Castrol 2T which is about 5x cheaper than the 2.6 oz containers of Echo power blend. $7.50 a quart for me.
I got Castrol for 6.28 a quart that's exceptionally cheap
Compared to anything else local I can get
Dominator, Schaeffer's etc..
I ran is 23-30.00 per quart now.

After the news got out about the 2T being equal with the Stihl, Echo, Fram, etc small bottles a few months back the quarts were oos everywhere. Skinflints are very active nowadays and I for one will seek out a deal like this. Why?

Green, ESG, and progressive policies are putting the fetters on the oil and gas industry. Add +20 years of lacking investment in exploration and production with waning production like Ghawar increasingly using injector wells to shore up their numbers and you have a future that will see much higher energy prices. You don’t even have to believe in peak oil as the EROI for future projects will prove unsustainable. I need to hedge that issue and being a guy that loves his 2 cycle engines the storage of 2 cycle oil is like any other hard asset. Those things priced in fiat will only go higher.

I'm not going to read all that
I bought Castrol cheap seems to work good
That is my statement.
 
Flash point doesn't infer what people think. A low flash point just tells you two things. A. The diluent used is high quality and B. It's a multi ingredient formulation. All FD certified oils are multi part formulations. IE they use a medium weight base oil that burns clean and a heavier weight base oil like PIB or in rare cases an ester for load carry ability/ scuff resistance.
High flash point multi base oils are problematic because the diluent doesn't combust fully and this causes deposits. They also tend to lower octane because the cheap diluent are typicaly stoddard solvent. They also inhibit combustion and cause a strong smell. Oils with a high flash point that only have one base oil.
I actually tried a low ash type oil sold by the company I work for and I could tell almost immediately it was garbage because I could smell the solvent passing through the motor uncombusted and this was with a strato motor.
The other thing is on a MSDS the diluent is often listed as Stoddard solvent,naptha kerosene, etc. These are sort of blanket names for various hydrocarbon fractions of different boiling points and thus flash points. In other words you may see a MSDS that lists kerosene as the diluent and it's shows a 175 degree flash point and another that also lists kerosene as the diluent that has a 250 degree flash point. The higher one will often pass through the motor in a partially combusted or un combusted state when not subjected to high loads.

Very good points . Most of the higher flash point oils I have witnessed have been problematic . Although as you mentioned. Detergency packages can resolve deposit issues effectively , I always worry that they may contribute to cooling the critical temperatures & further aggravate deposit formation due to incomplete combustion & sponge formation in the exhaust runner . Ultra via BP oil of Shreveport la. has a flash point of 432 f . & a predictable carbon deposit & excessive sponge producing effect . Your analogy Ben most likely is spot on !
The cases of Go! 2T I picked up last week are refined by BP. BP has three US refineries https://www.bp.com/content/dam/bp/c...iness-factsheets/bp-refineries-fact-sheet.pdf

What difference might there be between the process of the US refining at Whiting and Toledo where this 2T is processed? Canada does not have any BP refineries as I can tell and only 7 exist worldwide where the Toledo-Husky refinery in Ohio is now sold to Cenovus.
