It was eye opening when I saw it honestly. @rogue60 have you got those pictures?
Old Macs , Pioneers, and ported get 32:1 regular modern saws 40:1 Motul 800 2T Off-road mix and non-ethanol 95

I got a lawnboy and a Jacobsen 2 stroke mower doubt the lawnboy will ever run again it was fed lots of ether by its last owner.
FC rated oils are always at least partially synthetic.
The whole group 3,4,5 things is geared more to motor oils. The synthetic base oils used in two cycle oils are predominantly PIB's or esters.
I am thinking the Aussie guy is referring to a straight mineral low ash oil.
Because the price of chemical feedstock has went up along with everything else. Most of those feed stocks BTW come from crude oil in one way or another.
Most every chemical, lubricant, ag chemical, fertilizer, etc starts out with petroleum of some sort.
I've seen it mentioned several times that real synthetic oils are "made in a lab" this is non sense. They are all made in a refinery in one way or another and from crude oil.

This 1/2 chain is non existent so are the presets and tie straps.
I would like to see these as well.
Here we all are stressing about the best oil, Rogue uses some of the cheapest mineral oil at 25:1 and his equipment, after thousands of hours looks cleaner than any other I have seen (internally) externally, yeah Rogue is the first to admit he’s not the kindest to his equipment but it’s certainly a testament to working saws hard, keeping the chain sharp and stopping stressing about everything else.
No pic of the crown or muffler outlet?
Also what specific oil is he using?
I have a drum of Rotella-T 15w-40 in the garage , just drop by & I'll top you up brother !
If I only lived a lot closer I would.I have a drum of Rotella-T 15w-40 in the garage , just drop by & I'll top you up brother !
Muffler outlet is pictured. You’ll have to ask him for crown pics, these are just ones he’s shared on the other forum. He’s using Castrol Gardener 2t. FB rated mineral oil.
could be like the Bel-Ray , it's a light grade synthetic used for both injector & premix applications . Depending on whether it is a Group IV or V oil will determine the various stock oil additives are used in combination with the Mineral base stock . As Ben mentioned a better look at the piston crown & exhaust ports would better indicate the oil overall package success . The piston rings on the pics look great , there is some carbon tracking on the crown & exhaust side piston skirt , no carbon etching however of the skirt , the port looks somewhat clean ? I would say for the hours indicated on the saw , the oil & mix ratio & saw tune is optimal for the elevation & application the saw is being used for obviously . I used FB & FC rated oils for yrs without issues , FD with it advanced low smoke & odour additive package makes things even cleaner for operators environment . I believe he was using a Castrol 2T Product .
Hell , Tex "Backyard lumber jack" flys in all the time , tops up on Esso 101 Sae. 60 mineral oil for his Cessina
Gardner 2T is also a Premix or Injector use mineral oil , as is the Bel-Ray product Scut207 questioned , both quality air cooled ope oils , there are better & a hell of less quality oils out there , Ultra ring a bell Ben ?
It's a big distillation process , as your quite well aware Ben . The terminology of Full Synthetic to Semi synthetic or synthetic blend confuses the mass's . All oil originates pretty well from crude oil & is refined into base oil / pale oil & then is blended with adder stock oils & additive packages through synthetics to provide a more uniform oil composition or monelcular design structure for best oil protection for its intended usage . It's frustrating that the actual amount of synthetic oil is used is relative . Some synthetic are 20 % synthetic others are 80 % only Full Synthetics are 100 % synthetic , however some are esters & some original pao bases that are very refined from crude stock .
Kinda not related, but..Alot of guys like to say group 3 isn't synthetic. This is non sense. Especially if one knew what went into making them.
Then there is the fact that 20 or so years ago Petro Canada produced a group 3 diesel oil that bested Mobil Delvac which was a PAO/ ester blend at the time. This was documented in an SAE paper.
Which brings us back to two cycle oils. I wouldnt get too hung up on what the oils composition is, but rather what tests and certifications at has actually passed
. No "meets or exceeds" garbage either.
