There is no reason not to switch right away. Modern engines are built with much better tolerances than days of old, and many engines come with synthetic from the factory. I have not seen anything other than anecdotal evidence, ancient advice, and recommendations for rebuilt engines that suggests otherwise.

My Frontier got the same treatment and ran perfectly until the day it was totaled with 53000 miles. If you are planning on using Mobil 1, keep an eye on the Costco flyer as they often have 6 packs on sale for $10 off. This makes the price almost 50% cheaper than auto parts stores. I buy them 2 at a time when they are on sale.

I used to buy Mobil 1 at Costco when they had a "coupon", but find Wal Mart (5 qt. jugs) to be less expensive. Mobil 1 has rebates on their website (Google Mobil 1 rebate) about twice a year (none active now), usually for $12 off 5 quarts. It's fun to be frugal.

The Mobil 1 rebates are back.

Note that you can purchase your Mobil 1 almost anywhere (except Amazon) and qualify for the rebate. The list says "some" participating retailers; receipts submitted from other retailers, like Wal-Mart, have worked fine in the past.

I didn't see Amazon or Walmart listed on the rebate "location" list. Anyone get it anyway?

You won't get the rebate if you buy from Amazon (per the instructions on the rebate site). Although Wal-Mart isn't listed, it has worked successfully for many people on many occasions before. Note that the site lists "some" participating retailers. I just bought a 5 quart jug at Walmart for $25.47 (plus tax).
