Hours on a mower

[bertsmobile1]

Profanities should not be used on open public forums or open radio channels
IT is some thing I picked up from a radio dispatcher decades ago
IT gets very frustrating when people who obviously do not know what they are talking about demand proof that I know they would not understand even if they could access it and of course defence documents are not publically available and university papers are all behind pay walls , if they are actually available from pre internet days
Even the simplist of people can go to any oil blender and most will happily show them how they blend their secret formulas and a general idea about what is in them.
There are literally millions of molecules that can get added to oils to modify the behaviour of the base oil and they are needed because the chemistry of base oils differ depending upon where they come from.
Near 1/2 of the heavy lubricating oils used in the USA come from Australian oil fields because the crude from Bass Strait is perfect for lubrication as it has a high sulphur contents ( bad for auto & syncromesh boxes )
And then you get the stuff that oil companies like to brag about like ZZDP which is not needed in a mower engine at all as the scuffing forces between the cam lobes and the cam followers is just not high enough unless the owner has fitted high strength valve springs
On top of that a lot of the cams are actually powder pressings so retain enough oil in their pores to maintain boundary lubrication for the time the followers are in contact with the cam and because the whole shooting match is vertical & not horizontal and lubricated by splash & oil mist , not a pressurised flow through a an oil gallery .

Well actually I do .
I studied oils as part of an undergraduate course then again in a couple of post graduate diplomas.
I have broken them down physically & chemically
I was part of the team who originally initiated X-Ray diffraction of used oil to work out the actual alloys that were in the oil, their particle size and percentages then this was plotted agains the actual measured wear during prescribed tear downs for inspection on defence helicopter engines & from this work whole new set of maintenance proceedures were derived with substantially longer operational hours between strip downs
Back then those with lots of brass buttons thought it was all some sort of hocus pocus but after the team predicted 6 engine failures almost to the minute they took notice
Then later did some work with Bel-Ray lubricants working on variations of their blends of motorcycle oils.
So yes I do have a far better understanding of oils than the average Face Book hero who has read the sides of one too many bottles of oil or opened a couple of oil filters with a can opener .
And FWIW the last project I did with the Defence Standards Lab, renamed the Material Research Labs post Vietnam when anything military was considered dirty was to use Accoustic Emissions for the testing of pressure vessels and in particular artillery shell casings & hand held rocket but the lab got defunded, outside contracts were all cancelled so the team was disbanded .We were all head hunted to come to the USA to set up the work again but I had committments down here so I stayed put & went into foundry metallurgy then tertiary metallurgy before becoming a workers compensation risk so went into transport & finally mower repair .
But in order to have an intelligent arguement with some one the other party needs to have an open mind and from the nature of your reply I seriously doubt that you fit that criteria
So you can take it or leave it I do not give a wrinkled rats rectum what you think

Still no proof.

Still no proof.

How about hundreds and hundreds of pieces of equipment being serviced and repaired?Seeing lots of “special” oil that is dirty, low, or overfilled? It is a low compression (usually 8.5 to 1) engine revving to a maximum of 3600 RPMs. How about a nice dab of humility with a splash of common sense? There is your proof.

I am going to ass-u-me that revb and Bert has some sort of history on here….

At this point I'm inclined to call your previous Appeal to Authority pitch on "expertise" complete bullshit and a lie. Your claim of a difference in mower oils and any other oils is hereby rejected. "Because I said so" is not proof and either is this last little bit of puffery.

Nah...no history. When statements are made that cannot be backed up with evidence....good hard scientific evidence instead of the Appeal to Authority type of "evidence" then it gets called out.

Kinda sorta sounds like you enjoy the argument

And as previously mentioned

If you want to believe there is no difference in the additive packages blended into different oils so car and mower oils are all the same just having different coloured dies in them to make them look different so it is all a scam then you are welcome to your beliefs .
I no longer get paid to educate people
And it is good not to take anything read on line as 100% gospel truth .
the information is there if you want to find it there are a lot of oil blenders who will be delighted to explain the differences in great detail and of course why their oil is better than brand X oil
Kohler put a very superficial explaination on You Tube Car Vs mower oil and if you do their certification course there is a more detailed explaination .
Noria ( a company I may or may not have had an association with in the past ) is a specialist industrial plant management company that specializes in fluids ( Lubricants, cutting fluids , oils & greases ) who put out an excellent range of publications that are now mostly on line and have a comprehensive set of publications as well as training courses
On other forums I have used their E-Zine Machinery Lubrication to explain the difference between Detergents & Dispersants which thanks to You Tube idiots now seem to be interchangable , although Detergents are dispersants but dispersants are not detergents and neither of them actually clean a dirty engine , that is the job of solvents & alkanizers
I think it was Simon & Garfunkel who sang "A man hears what he wants to hear & disregards the rest "
And this is generally the mind set of those who come out with a simple "Prove it" and no matter what is said or done they will neither listen nor try to understand.
Some one who want to know will say "Please explain"
After all there is almost 1/3 of the US population believe President Trump actually won the last election to the point some were willing to put their lives on the line to prove it .
There are people who believe that G5 phone towers caused Covid 19 and if you say otherwise they come at your with a "prove it"
And despite what is happening right now the climate change deniers still say "prove it "

And with this I shall bow out of this post as it is no longer serving any useful purpose and will very quickly degenerate into a slinging match .
