Your Nissan Factory Warranty gives you basic coverage for 3 years or 36,000 miles on your Nissan. Have you explored what Nissan Extended Warranty coverage can do for your Nissan vehicle?
Agreed with Irongrave, they are not fans of the winter gas. Then again, not sure I've had a vehicle that has been ok with it.
As far as your MPG's go - about every few weeks, a new member is talking about how they seem to get worse gas mileage during the engine break-in. This is not a fact, but just what I've heard!
