Title: 4 stroke engine oil Post by: cannon on November 03, 2009, 09,59:36 AM has anyone used motul 5100 ester in a ktm 450 03 model
i purchased some . havent put it in yet. i thought it was full synthetic oil. the manual tells me to use fully synthetic oil. after checking motul web site it rekons its semi synthetic oil. damn expensive for semi synthetic . any help would be appreciated. rob Title: Re: 4 stroke engine oil Post by: chrism on November 03, 2009, 11,33:02 AM I use belray 4 stroke thumper, which is semi-synth. Don't quote me on this but a semi offers more protection than a full. I would go off what the bottle says motul is suppose to be pretty good oil.

KTM are tied in with Motorex, which is why they would recommmend it and would not provide opinion about anything else. In the end it is your bike so your choice. At present I am using Castrol oil for the bike, and will probably use the Penrite oil when I need more. The leftover Motul I have is now serving as a doorstop. Mat.

Again it is personel choice, before the KTM I was using Penrite SIN 10 in my XR and still use it in my son's XR and again with out any issues. Regards Will. 5 litres of Penrite Sin from the club is around $64.00. if you need any just let me know and I will organise it for you.
