which oil

[Carbon_ZX6R]

bit of a strange one , needing to do an oil change on the duke as ive poured most of it over the road , all i can find is everyone online saying it must be fully synth must be fully synth etc , but im always told to follow the manual of which it says and i quote "partially synthetic" the recommend motorex formula 4t as the oil , but is that going to be sufficient giving the type of engine it is?

what im trying to work out is who seems to know best , the people that built it , or every single person that rides one

I would always go semi-synth for road riding.

[Carbon_ZX6R]

Even due to the "race" like engine of the KTM? What I mean to say , is there a disadvantage to running fully synth other than the increased cost?

The manual is written by KTM, the bke is biult by KTM, they recommend semi - synthetic therefore use semi - synthetic as that is what KTM - THE DESIGNER AND MANUFACTURER -  recommend - simples 

Did you say on another thread you were a trained engineer.........................................................................

"qualified mechanic"*
(loosely)

ive just checked the service history , main dealer put in completely different oil 10w60 fully synth when should have been 15w50 , and another dealer put in 10w40(has in it at present)

i would always go with what the dealer recommends but when i cant find anyone that actually does go with that recommendation , including main dealers , it makes me want to ask questions

Do you have a owners manual?
If yes use the oil recommended within the Specification page.
What previous buffoons have done should not concern you...you are in a position to right the wrong.

[Tiiimmmaaayyyy]

What would you have done if the previous owner had put chicken soup in there instead of oil? Ring a KTM dealer, look at the owners manual, google it, but whatever you do, put what is supposed to be in there, in there.

Was you mechanics course by correspondence with a 'university' in India?

I use fully synthetic in all my KTMS. 10-60 on the singles and 10-50 on the twins.

[komp]

my ktm's manual doesn't state if semi or fully synth
just that it should use 10w50
last lot i bought was fully synth tho

[Alzo]

If the Break in period is over Fully Synthetic will be fine.

[Carbon_ZX6R]

the conflict im having , ktm swear by motorex

they recommend motorex formula 4t which is a semi
i can get the motorex fully synthetic for same price £11 a litre in the same weight

I know how you should decide...
