I have a KTM RC 390 for which I recently got the engine oil changed. They changed the oil filter too and they used 1.5l Motul 7100 4T as recommended. Thing is that I noticed the oil level is not between the mark that should be and I checked it a couple of times. Then I checked with the KTM service and arguing with them, they drained the entire oil and showed me the oil that they used in a measurement jar. I got some assurance and then got the engine oil filled again. They mentioned I can see the right level during morning but no way and still its at that low level when I checked the oil level keeping the bike upright. I have seen threads mentioning you might have to fill in 1.6-1.7l to get the right level. And these KTM guys also mentioned the same that they had to use around 1.6. But I am just not getting the right oil level that it should be. What is your opinion on this guys?. I am planning to do a minor top up on my own to get the right level. Whats your opinion?
