i am coming up on my first oil and filter change. i have decided on using 5w-40 rotella t synthetic. and changing it every 3000 miles. any one ever had problems with this oil? i have used it in other v-twins with no problems. price is no object. i would change every 1000 mile if i thought it was necessary. i used mobil1 10w -30 in my speedstar warrior with no problems. the engine looked like new when i tore it down to install the patrick racing pistons and speed star cams.
