Had oil changed recently. The dealer used Repsol 5W-40, full synthetic. I was surprised, because when I had the 1st service done, they used Repsol 10W-50, full synthetic. I inquired further, and was told that it is better for the cold months ahead. I suppose my warranty is intact, because the dealer installed that oil. But, part of me wants to run out and drain the oil and replace with 10W-50.
Anyone else using 5W-40, full synthetic? Any horror stories? My bike is a 2006 Monster 620, street-ridden.
