Intercooled, I was actually just looking into this too in the last few days... There is way too much positive feedback out there, and benefits (longer between changes for one) on the Mobil One synth or other synthetics in general...

I don't think it's a question anymore of is it a good idea, I think it's a question of, do I want to spend the extra money. I am a cheap bastich (an insult that is apparently a combination of the words bastard and bitch), and believe it or not, have brought my past Hummers to Mitsubishi dealers or whoever had the $14.99 oil and filter change in my mailing coupons. I have never paid more than $17.99 for an oil change and will try to break the habit next time for the Mobil One Synthetic...
