Im getting ready to change my oul. I have been using valvoline 15....40. Im thinking about synthetic oil? I have 217 on my 02 7.3. Good bad? Im first time diesel owner. Thanks, Fonzie

A popular Synthetic Oil for the 7.3 PSD is Shell Rotella T-6 combined with a Genuine Motorcraft FL-1995 Oil Filter.
You can buy both of these items at Wal-Mart and they have the most competitive prices.

Right now, you can get a deal on a bulk order of (3) 1-gallon jugs of the Rotella T-6 for $55 but you will need to buy a 4th gallon at regular price of $21/jug.

Shell Rotella Synthetic 5W-40 Motor Oil, 1 Gallon (Casepack of 3 units) - Walmart.com

I have found my local Wal-Mart does not have the "Casepack of 3 jugs" on the shelf EVEN if they have a dozen 1-gallon jugs they will not combine them for inventory reasons.

The best method to get the bulk price is to place your order online using the link I provided above.

And then just enter in FL-1995 and search to pull up the order info for the Oil Filter at $10 online price vs. $11 in-store shelf price.

If you want to stick with Valvoline they make a full synthetic 5w40 for about $5 more a gallon than Rotella.
