My max is an '07 I bought used in October of '09 with 2,300 miles on her. I ride 50 miles a day to work and back, not including any weekend trips for fun. So, I am racking up the miles. I changed the oil last week at 3,000 miles and I used Valvoline racing oil 10W40. I DID NOT use any X1-R or Z-Max (thankfully), and I won't - now that you guys have made me aware of the inherent problems and issues connected to oil additives.
Someone tell me about this Shell Rotella 5W40 oil. I also own an '03 Ducati Monster 800, and Ducati uses Shell oil. Some of you use it in your Max's, and I am curious as to what is special about this oil.
