Is anyone running synthetic oil and if so what grade? Also, has anyone heard of Rotella T synthetic oil? My dad runs it in his bike and swears by it that is the best.
Royal Purple 5w30, car has 19500 miles on it and no smoking or oil consumption. It costs me $7.75 qt. here in san diego but I think it is worth it. The price makes a lot of people go for mobil1.
Should be $5 a quart unless youre using the racing oil.
