Is your chain oil sticky??

Stihl synth plus chain oil is rheopectic- the opposite of thixotropic.

 

What's the first thing you do before you open a bottle of sauce, such as ketchup? You shake it, so it pours easier (thixotropic) so it gets thinner the more it is agitated.

 

 Stihl synth plus oil is the opposite of this (rheopectic) when not being agitated by being flung around a rotating chain it stays very fluid, so it flows easier through the pump, oil holes and the bar itself (unlike traditional chain oils) but then thickens up like a traditional chain oil once on the chain and agitated.

 

I found this out quite a few years ago when customers complained the 5l cans they were buying sounded very 'watery' inside when picked up.

Great post and very informative!!!

Thank you

So stick with stihl synth plus then? I guess those crazy germans know what they're doing!

Just use whatever the makers tell you to use.. What i mean is, you might "think" the synthetic is better, but the owners manual of one of my ECHO saws says not to use synthetic oil as it will cause damage to the plastic bits..

Here you go..

Not read any of this thread since June but I mostly run older saws and had noticed that my usual oil, medium viscosity from Northern Arb was running through too quickly and not that tacky.. I'd normally expect the oil to last at least 2 tanks of fuel.

Switched to Gator oil ET50 which is SAE 50 and it's as tacky as I remember chain oil to be in my youth.

 

So 20 litres of the tacky stuff is the same price as 25 of the thin stuff... I'm definitely using less oil and what gets used stays on the chain much better... but the chain cover needs removed and cleaned more often due to increased build up of sticky chip and it's much more of a mess on your hands.. so pros and cons👍

I was using some stuff called "barguard" from Rock oil. This was well tacky stuff. The local dealer i use stopped selling it so now i use Husqvarna premuim chain oil. This seems ok.. Given a choice though i think i would prefer the nice gooey stuff, just cos it seems "right" if you know what i mean..

Seems a few various types with different properties....

 

 

I always wonder what extra secret ingredients  goes in the the commercial  chain bio oils V just plain rapeseed cooking oil

Rapeseed oil  viscosity is:  (no idea google gives some different figures)

 

 

Seems it can be processed to get different viscosities from the same base ingredients?

You can always request a MSDS for the stuff as even if it's special they have to list all ingredients.
