The plain truth is that fuel efficiency doesn't come in a bottle; it comes through behaviour modification. It's kind of like weight loss. :grin:

Tell me about it...lol

I don't use synthetic in my daily drivers purely for economic reasons. A good quality dino oil is more than sufficient. I do use synthetic in my '98 Cobra cus I only change the oil once a yr. I also changed from the Ford recommended 5w20 to 10w30 and stopped some minor oil consumption.
