Ok I can not speak to that oil as triumph recommended mobile 1 4RT 15W50 FOR MY 06 AND 07. THE 10W40 was listed as a secondary choice. I ran the mobile 15w50 for 42,000 miles and had no complaints even the 24,000 miles with the TTS kit and know problems. Most of the the time I change oil at 5,000 miles. Once I modified the internals I switched to a higher grade racing oils that had more additives and less epa monitoring but still stay with thhe 15W50 weight. I have say I like Motul 300V 15w50 rt and Red Line 20W50 depending on my riding style I shoot for 5000 miles on both but if she starts feeling like its loosing its lubricity say after 4000 miles or so which I can feel in the clutch and transmission. I change it out. Good oil is better and cheaper then Good engine parts.
