Looking good! I personally run Petro-Canada Duron HP 15W-40 HDEO in mine with a Fram XG2 synthetic filter, which I standardized across the fleet. Prior to that, I was running Motul X-Cess 8100 5W-40, but decided I wanted to do more frequent oil changes. Then again, my engine is not stock and sees red line very frequently.
Basics you need to watch out for around here:
- Air filter. Do NOT blow it "clean" with a shop gun. You won't be able to get all the fine particles of sand out, you'll just end up loosening them to be sucked back into the engine. I replace mine at 3,000 mile intervals.
- MAF sensor. Clean this every time you replace the air filter.
- Throttle body/IAC valve/EGR valve. Depending on fuel quality, you'll want to keep an eye on it for carbon build up. Personally I pull them off and let them sit in a bucket of 50:50 Simple Green and water overnight every 6,000 miles.
- Coolant. A 2 year/25,000 mile interval is decent. Many folks run G-05, my personal favorite is John Deer CoolGard-II, which is difficult to source locally, so I run G-13 (30% coolant to 70% distilled water).
- PCV valve. Replace this every time you change you spark plugs. My interval is 30,000 miles - this includes spark plugs, COP boots and oxygen sensors as well. I have two sets of injectors, so the serviced set goes on and the set I pull out goes to Trav.
- ATF. Ford put a thermostat in the cooler, temperatures in excess of 200 F are not uncommon. My unit is anything but stock, so I upgraded both my cooler and transmission pan. That said, 10,000 miles is a decent interval for the stock set up. You can get an aftermarket pan, or take your stock pan to a shop to put a drain plug in to make things easier.
- Differential fluid. I run Motorcraft 75W-140, which is what the manual calls for in the Export market. I got a Torsen T2 in mine, along with a GT500 differential cover, and do a simple drain refill every 6,000 miles. Depending on how you use your car, 30,000 miles might work best for you, along with the tune up. The rear end is a weak spot in this application.
- Brake fluid. I run DOT 5.1, DOT 4 or DOT 4 Plus is just as good, and change it out annually.
- Power steering fluid. Flush this every time you service your differential, I run Pentosin CHF 11S in mine.
