661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[KG441c]

IMO its a mistake to classify these oils by viscosity and trying to tune by ratio. Bottomline for me is we are only looking at the topend and performance. I run 32to1 mostly for bottomend residual. If u go higher in ratio the bottomend will suffer especially on ported saws

any want to to use these? i have used them in the past with good results. they are made by spectrum lubricants who blends and bottles most OEM chainsaw oils. they cost between 50cents to 1.79 you can get them at hardware stores or autozone.

Jetting may be required on some mtronics /autotune saws to run 32:1?

Question regarding a larger jet .............. wouldnt the autotune/mtronic just close off more or more often with a larger jet ?
Its still going to hunt for the most RPM by reducing fuel, then looking to see what the RPM does ............... in my mind I dont see the larger jet making a big difference on these saws. It might be more beneficial for in between throttle settings, like coming off a long cut, or piss revvin after a cut to get additional oil for the chain

Or if the jet lets more mix in it will increase rpm until it reaches its max rpm? Not sure

Piss revving makes me happy .

i use a gallon jug of lucas 2t every 6 week burning 5 gallons per week of lucas at 32:1 i dont have a problem.

Yeah but this is a chainsaw forum, not a lawn mowing forum.

I wonder if the L jet and transition jet could be modded to help the lean run on after a cut.

Emailed maxima, klotz, lucas, amsoil, belray, motul, and yamaha. all responded quickly except yamaha which hasn't responded at all...been 2 weeks.

Have called them all as well. Now on hold for yamaha ...what a total pain in the azz it is to get ahold of these guys.

anyone have a contact at yamaha that i could talk to about 2r?


update: just got through - oh brother. we would not recommend that oil in a chainsaw. well could you tell me at what temp it falls out of suspension...how cold can I use it at once it's mixed in with gas? ...every question I had = contact your local dealer. Is there someone there could help me further...no this is the distributor for north America you'd have to talk to japan OR your local dealer. " how annoying.

on phone with local dealer - ugh. worthless.

bwalker where are ya - once mixed with gas - at what temp does 2r start to fall out of suspension ? Don't tell me it doesn't. At least one of the additives etc Will fall out of suspension.

what about adjusting the inlet needle height in the carb?

I have ran it premixed in sleds at 1o below.

That piston and its ring lands are ugly
For me, its too lean and could use more fuel. (going by the pic of the muffler)
Cant tell how much or how little oil is in the ring lands .............. that lets me know that there isnt enough oil

I dont mind a little oil in the muffler, and I dont like a white exhaust.
Thats 2 strikes in my book

Assuming the saw is tuned right, here is nothing wrong with the way that muffler looks.
I think alot of you guys are just not accustomed to not having a saw tuned overly rich.

when it comes to the lucas oil next time actually touch the piston and exhaust port with your finger. the oil dries to a goo when the saw cools kinda like what winterizing oil does to an outboard or any other 2 stroke. i've ran and been into a few saws now that have ran it and there is always oil in the case. if you wanna see a film of oil on your piston fire it up and just run it for a few seconds then pull muffler off the check again. lucas does leave oil. not sure why it dries to a gooey film in the top end after a heat cycle but it would sure be good for saws that sit for long periods of time. after seeing what the crew's here run i have been alot less picky about the oil i run. like alot less. i've even been running a little of the budget **** off the shelf at gas stations. it's hard to give up 32:1 though but i have been contemplating switching to 50:1 as the falling crews run that and their saws last way longer then anyone would expect.

Mine doesnt...

 

[Big_Wood]

neither do mine.

 

[Deleted member 83629]

my dads 545 runs better on 50:1 than 40:1 or even 32:1 but that was with motul 800.

 

[bwalker]

If Autotune can compensate for a 80 degree swing in temp, the differance between 32 and 50 should be no sweat.

Thats a BIG assumption ................ I wonder if the plug is white too ?
I dont agree with you on the muffler, I have been doing this 2 cycle repair stuff since the early 80's ................. white mufflers are a precurser to an early death IMHO

Looking for an oil with dye in it ,this says injector or premix ,is it a bad idea for saws ? Being recommended for marine use also ?
this other stuff has some red dye in it ,may be better ?

You are really liking this Dumonde oil eh ?
