Full synthetic or semi???????

[predator]

HELLO AGAIN EVERYONE

 

i,ve been mullng over in my head etc the advantage of fully synthetic 2 stroke oil as if it would be the differance of longevity & semi seize or not seize if i had been using semi 2 stroke at £22 for 5lts or £32 for full synthetic as i,am lucky to have a oil refinery on my doorstep so have a choice of many oils to choose etc as they blend all there own oils and have done so for years caldo oils st helens

 

whats your views please as i can pass this knowlage onto my good friend sean who makes his living same as you boys on here etc"" and had an amoury of saws strimmers etc etc so lots of 2 stroke oil used etc

 

ps i will see if they do semi syn chain oil too but not sure if its option and its pro,s n cons costs etc

 

but after this post i just maybe trying to fix somthing that aint broke etc but would like to here and take your advice as i said mulling it over as its used in high stressed motocross bikes being revved flat out red hot etc etc

Semi-synths perform better than a mineral in a 2-stroke application due to the fact they don't lubricate for very long! Full synth, well what is full synthetic? Sure it aint dino oil but is it a group 1 or 5 basestock?! Mineral cracked vs poly-ol-ester, with pao in between. If you want the ultimate poe, Redline Kart Oil is the kiddy. Some of the upper Silko sits just below this level, all high end. Check the JASO...

I have always used husqvarna's xp synthetic oil, i have been told its better at lubricating the bearings and engine better and keeps engine temp down a little more, than a standard mineral based oil.. and i haven't had any saw problems ever!! with regards to it seizing.. i think it's more down to percentages in my opinion.. i run them all at 40-1 hope this helps..

Many years ago, too many to even think about and spoil the weekend reminiscing.

I was sponsored by Century oils, they did a good two stroke oil with a very red dye. All I ever seen it in was a gallon can dropped off at my door whenever I was running out. My Husqvarna enduro bike was run at 40:1 and never ever had any trouble with it, I used it at 50:1 in all my saws too at the time, same results all worked perfect under al conditions.

Havent seen Century around for years but maybe they are still out there, may even be under another brand?

 

ps; the red dye you couldnt miss & it smelt good so probably synthetic or semi??

why gee thanks!

 

sarcasm will get you nowhere

 

The unstandardised canonical discriminant function coefficients of the small and large molecules after sustained high temp are nigh on impossible to simulate!!!
