Since I bought my Used '13 RTL and planned on putting on (what for me) would be significant mileage
(we're not talking Ann and Joe's mileage) I wanted to test the oil I had most access to
(Castrol Power1 4T 5W-40 Synthetic Motorcycle Oil) over a few oil changes to make sure I'm protecting
my engine well enough.
So after ordering filter change kits from BajaRon, oil from Amazon, I tested starting with BRP's Oil,
then with the Castrol over a period of 4 changes. My final oil analysis after a recent 4800 mile trip,
I'm satisfied that the Castrol will be effective. For the curious here's the recent results,
Before

and After
