What oil is best? and what ratio?

That lawnmower on the label must be one of those old green 2 stroke Lawn Boy's.
My first lawnmower in 1979 was a lawn boy.

Lawnboy mowers actually spec a TCw3 outboard type oil.

Hmmm. Cool. I wonder why it is not available in the USA?

My guess is california hipsters and the epa. Lol

Was that the spec for a Lawn Boy in 1979?

Ironic that these spotted owl crusading tree huggers now have to deal with some wild fires.

As mentioned earlier about USA Stihl mix blended by Omni Speciality out of Louisiana.

I'm posting pics here of our Canadian Stihl Premium orange bottle mix with the Castrol logo and 32:1 40:1 50:1.

Gotta love seeing the 32:1

I am still kicking myself in the @$$ for not filling my motorhome storage bay with good Canadian Scepter brand NON PHUKKIN EPA gas cans the last time I went through on the Alcan



Epic FAIL

Yes, they speced outboard oils back then. Of course TCW3 wasnt around until the late 80's.
The reason for this is these engines run at constant RPM and they really build up mettalic ash on the head, piston and sparkplug. This causes pre ignition and plug fouling. The trade off is these motors also run hotter and under less load than an outboard. As a result of using TCw3 oils they can have problems with exhaust port pluggage, piston ring land deposits and in general dirty running

Wonder why a air cooked lawnboy wants tcw3 oil. I mean its 2 cycle and air cooled one would think it would need air cooled low ash oil. Also in my snowmobiling days we has free air fan cooled and liquid cooled sleds. Dealers said to use the same oil. Weather it was artic cat or yamaha they said the same. Only stuck one sled that was freeair on a 40* day riding in the slush kinda slow.

See my edited post above.
Back in the day the snowmobile OEM's did spec TCW3 oils and with terrible results. Especially when snowmobile engine BMEP increased and the engines began to come with power valves. The quickly began recommending low ash type oils.

It happens here too, greenies fight & resist any plans to back burn and manage combustible fuel loads in the bush as they fear an animal might get hurt, then when a bushfire happens its uncontrollable and EVERYthing gets wiped out. After our last black Saturday fire where a couple of hundred died and lots of property burned, a royal commission was held and the rules got changed. Now back burning is common practice and permission is not required to fell trees within 10 meters of a residence. Anyways back to the oil, we too get Castrol produced Stihl oil which I'm quite sure is different to what the US has on their shelves. Folks have been running it for decades without issues & many farmers and saw users won't use anything else.

I prefered a synthetic oil in my old KDX-200, but when I was going cross-country, like up to the 'Tip' of Cape York, I used what seemed to be available everywhere in OZ - Castrol mineral oil Super TT. It was FB rated and never gave me any problems.

Can someone fill me in on H1R please? I've missed a lot in a few years....and just by hitting the high spots at the beginning of this 703 page thread im not sure the answer is here lol.

I will say, Ive used at least 4 or possibly 5 of the big 4 liter jugs ( about a gallon iirc) of h1r without issue over a few years in about 15 different various 2 cycle ( and a few 4 cycle lol) engines at 32:1.

 

[Clemsonfor]

I dint know there was an issue?? Last I was paying attention that was the flavor of choice?

Some guys reported weird running issues mostly in autotune or mtron saws. If it works for you, carry on is the general consensus

Oh ok. I think I remember something about that. Reading a few years ago? I don't have one of those new fangled saws so I didn't worry with it
