the motor has high kms its at around 243 right now, i think the prev. owner ran just normal oil, i always ran mobil 1 in every car i have owned but i dont want it to start burnin oil, and possible other bad stuff like leak at the seals. i havent ran conventional oil in a while whats on the top for oil now. and what weight should i run with. thanks everyone ---

As per owners manual, I run 5W30. I happen to use Mobil 1 synthetic. I know it’s thin, but in keeping an eye on the level, I don’t lose any at all, and it stays clean. ---
