Opinion on fuel removed from saw

[ijpom]

I bought a used saw. Lets say it was from someone more of a newb than myself. "The saw doesn't work" they say.

So in checking out the saw, I pull the spark plug, checked for spark, confirmed the air filter is clean and drained the fuel (red/brown liquid in fuel receptacle).

Ignoring the low quality containers (which were clean enough to put fuel into) left to right is:
Old lawnmower fuel without oil (useful when rebuilding carbs)
Unknown fuel from used saw
Fresh 16:1 fuel for other saw

Anyone seen that color before? Could it be an OK oil, but a few years stale? Is 2 stroke oil made in red tones?
I fear the saw ran gas/motor oil mix before I got my hands on it. Maybe that's the color?

Any input welcome.

PS: the saw runs but smokes on 40:1 more than my Craftsman smokes on 16:1. Could just be oil in the exhaust that will burn off. Time will tell if my $40 purchase was wasted.

Old stale fuel will smell like ****.
But as far as the fuel in the milkjug, you need to throw that out, as it can destroy any engine that tries to burn it.

Run fresh 32:1 and dump the rest. Carb cleaner is for cleaning carbs and air is for cleaning saws. You can clean dirty saws that you want to repair with that old fuel but they will absolutely stink to high heaven.

Rule to live by- never trust another's fuel mix.
That and a secondhand saw is not a new saw, you pay your money and you get someone elses leftovers. Only way to beat that is to buy your saws new off the shelf.
You cannot reverse what has been done to a saw in the past- you can only hope it has been fairly treated in its previous lives.
Dump the drained fuel mix, clean the carb out, clean the saw up, mix your own fresh fuel and go cut some wood. Could well be the muffler is full of oil and will burn clean eventually, or you could take the muffler off, inspect and clean as best you can (if it is a sealed muffler) and rinse out some of the crud.
Maybe the saw was run on some kind of engine oil gas mix, but that is better than straight gas.

Here in Europe we have several red fuel oils

I would suspect it sat for a long time, most the fuel evaporated & the stale stuff that was left was half oil. That would explain it not working & then smoking due to the excess oil build up in the crankcase.
Make some fresh mix, run a tank through it & it'll probably be fine

Klotz is red. Lots of oils are red. Doesn't mean much. Now 16 to 1 dear lord that's a lot of oil.

I dump the mix out of any saw I aquire before I even pull it over.....

16:1? You’re gonna burn it up kid. I use a 1:1 ratio. More oil is more better, manufacturers these days are just shooting from the hip with their 50:1 recommendation. Go big or go home, now hold my beer and watch this...

Hi Thomas,

I'm getting that advise from many of the members of AS.
My Craftman 2.0 from 1980(?) calls for 16:1 in the manual and on the fuel cap, so I gave it that ratio. And it runs. As I newb, I followed those directions.

Since wandering around AS, I've seen a few of the ratio debates, asked a few questions regarding my particular saw, and have mixed a 40:1 fuel for my second gallon.
This should make me happier with less smoke produced, and please the more experienced saw guys too. I'm advised the saw will be fine too, after re-tuning.

Keep felling the trees!

Yep saw will be fine, likely the 16to1 was a carry over from 30 weight days. I have saws much older then yours that run happily on 40 to 1. Cheers

A darker shade of oil for fuel is only given by the most expensive / supposedly best ones

+1

And, I’ve found:

Almost four tablespoons of water. (026) That one was the all time champ.[emoji848]

Full tank of diesel. (MS460). Tree service saw can you believe.[emoji2955]

Weird **** that separated in two distinct layers. (021)

Lots of loose fuel filters. (too many, really)

And saw chips, naturally.

Dark green synthetic mix 16:1 if not 10:1. [emoji2960]

So, not to give everyone ammunition regarding 2 stroke oil, but here's what I've got.
Should I go back to 16:1, because it's so bad?

This is just a foreplay ;-) before the oil theme

Subject has been breached. Now an official oil thread.

FVP two-stroke oil is red.
Myself, I never use any brand of red two-stroke oil.
I only use full synthetic Amsoil two-stroke oil... and it is dark blue. This way, you can tell at a glance that you remembered to mix your oil into your container of fresh saw gas.
