What oil is best? and what ratio?

[jakethesnake]

I’ll speak up. I’d quit running the lucas. Lost a bearing due to that *s-word. My other saws were dry as a “popcorn fart”.

Search under my name I posted it in this thread

If you are gonna use it. At least go 32:1. I think it’ll be ok at that ratio but 40:1 failed me

I wouldn’t run it at 25:1, but he likes it and it’s working for him, so there’s that.

Sadly.

Well, you are the one that let BWalker back for the umptheenth time, don’t blame us common folk…

He enjoys the banter.

I agree. It worked for me too. Until it didn’t. Incident wasn’t isolated either. It was everything I was running.

Good evening Jake, thanks for the warning. I was able to find your pictures of the ported husq 346 back in 2016? Had you also mentioned that saw was hard to get enough fuel during tuning?

Yes I have no doubt that if something sat for a while, the lucas stuff would evaporate out. I had wiped a bolt on a rifle with lucas 2 cycle oil. Put rifle in the gun cabinet and it was dry couple months later. The oil evaporated away.

Stay tuned when I tear this cs 590 down, after a year of cutting. 32:1, 90 octane, 2 oz marine stabil per 5 gal jug. Though many of my other saws have run on all sort of other oils, the 590 has only ever run on lucas, since new.

In all the saws I've gone through about 25 gallons of this mix since last February. Lucas oil in the yamaha enticer 2, about 4 years of pulling slabs, firewood and a trail groomer (tractor trailer tire).

Tell you the truth I don’t remember every detail about that saw. It did have a larger carb on it though. It was finicky to tune. Just needed to be done weekly. (Annoying). What failed was my crank bearing It just wore out enough to allow too much travel Piston ended up hitting the top of the cylinder Internals were dry so I grabbed my perfect running 272 and pulled the muffler. Far too dry for my taste. I put 2 and 2 together and switched oils. (Went to cheap husqvarna “low smoke”). After the change everything was shiny inside after checking insides at a later date.

At 32:1 you might be ok but in my uneducated opinion it’s just not a very good oil.

I can run red armor at far less ratio and still look good inside. I don’t pull saws apart just to check as I don’t care that much but I do occasionally have an issue that has me pulling carburetor or muffler and haven’t seen anything since switching away from the lucas that caused me any concern.

Any of you fellas know if egg tested lucas ? How did it do? Poorly I’d imagine

 

[jakethesnake]

Also curious. Does anyone know if marine stabil contains any oil at all? If it does it could also change things for the better if you’re adding it to your fuel

 

[Joe Kidd]

Doesn't appear to have, just >60% hydrocarbon solvents. (Stoddard solvent; (Mineral spirits, 85% nonane and 15% trimethyl benzene)

Thanks for doing the leg work joe


I will be curious to see how the lucas is working for you Mainer

He did. It didn't do well at extreme ratios.

Kinda figured as much. Thanks

 

[Motorka]

Me looking at this ratios different.
For example if old h61 372 oe used 32:1 and engine consumption of fuel mix was 10.
Newer saws with x torx and autotune use 50:1 and consumption of fuel mix is 6?
Newer saws are fuel efficient with lower oil mix . so they have harder "life".

 

[redneckhillbilly]

new 592 owners manual says 50:1 mix, nothing about engine displacement, or commercial use.

just though this would be a good reference for this thread, not trying to argue, I use 40:1 dominator in all my 2-stroke stuff.

Yes 32:1

What about hard work on a cold engine?

It did so poorly in fact it was deemed not worthy of further testing.

Sounds like my evaluation of it as well

What ratio was the lucas tested at?

It's a very thin oil and the flash point isn't very high. These 2 reasons are why I like it in the below zero weather. It pours from a jug at 30-40 below zero. I can also get a snowmobile to start in these cold temps.

Napa, oriley, auto zone all seem to have it which is convenient. It's well priced @ $9.99 a quart.

With the oil being as thin as it is, i thought 32:1 was proper for all the hand held stuff.

Then in the saws, after 25 gallons of mixed fuel, milling, cutting down stumps and all sorts of cutting, I haven't had an issue with the lucas oil. 8 saws total.

I think March 1st will be the 1 year mark on that cs 590 used 3-5 days a week.
