Deanyel, I am in Northern CA, Sacramento area. I can't find my manual at the moment, and after I found the old bottles of 20W 50 in my trunk, I decided to do the post. I used the 20W 50 when I lived in Los Angeles. I'm not sure now that Kragen's advice of 5W 30 is the best? I do change my oil every 7,500 miles, probably earlier than that. I used to change it every 3,000 like I do with my Miata.

It's my understanding that by using the synthetic 'blend' I could go back to regular oil if I wanted to. That is why I was using the 'blend'.
