  1. Do you notice any difference in gas mileage with the regular?
  2. Hey all, I was wondering - is there *any* difference at all between the 2001 & 2002 VQ35DE engines? The reason I'm asking is this: my 2001 manual says that premium fuel is required. If you take a look at a 2002 manual, it tells you "for maximum vehicle performance, use premium gasoline. however, if premium is not available, 87 octane can be used". So I'm wondering if there is any difference in the timing setup, sensors, tuning etc between 2001 & 2002 model years that would allow you to put "required" in one and "recommended" in the other. Reason I'm asking is that I'd like to drive this vehicle more - actually I'd like to make it my daily driver - but I have a long commute and the worse gas mileage (approx 10mpg less than my other car) coupled with the premium, ends up costing significantly more. If I could dump the premium, it would be more competitive in cost. On the other hand, I don't want to end up with CEL problems et al by using 87. Thoughts? Anyone struck a happy medium on 89 instead?
