Gas octane
#35
I went to one of the two gas stations around here that sell 100 octane a couple of weeks ago to fill up. They stopped selling it so I had to get 93. I still have one more gas station to try. Hopefully they still sell it because I want to give it a try in my HHR.

From what I have learned, synthetic oil reduces the friction so theoretically (sp) the car should spin easier. This means better gas milage, more power, and less wear and tear. In todays new cars that have fewer scheduled oil changes, synthetic oils break down slower, so they last longer.
In short, most everybody recommends them. (Unless you change your oil frequently, then it wont be in your engine long enough to be worth the cost.)

That is why I've heard no change to synthetic until after 10K miles... although my SAAB came with Mobile 1 and no scheduled oil change until 15K. Good thing I leased it!
