Ok guys i have ran this klots 200 oil for about 3 yrs now, and i didnt think i had much problem, Now i have checked all the pistons on my motors and this is what i have found
My os motors Piston are pretty clean, But the glow plugs themselves are near black ( Not sure if this is ok ) But are still working fine
But my THunder tiger motors pistons have got plenty more carbon build up not sure why as my os motors have had more run time.
i have also checked my 4 strokes and the glow plugs are black and still working and the pistons are pretty much squeaky clean
ok In my 2 strokes i have been running 5% castor, 15% synthetic ( Klots 200 ) and 5% nitro. Should this be ok?
and in my 4 strokes i been running 20% synthetic ( Klots 200 ) 5 % nitro...

Now my question is, Is it normal for my glow plugs to be this black ( I do run them rich but not overly rich )
and what is an alternative good oil to run in all My motors being from thunder tiger 46 to 120's to Os 46 to 160, also dont forget my 4 strokes I mean is the Klots 200 Oil no good at all?? i normally mix 5% of cool power fortiied castor in it anyways...
Cheers.
