Regular or synthetic
Ok my 2000 has over 150,000 I just bought it over 2 wks ago. I want to know if I should switch to synthetic or not. How could I tell what is in the engine right now without taking it to a dealership. I have heard so many bad things about going to a synthetic with alot of miles when it has had regular oil in it.

The greatest problem usually encountered when switching to synthetic in an older engine is that if there is a weak spot, it will start leaking. If it were mine, I would use the Motorcraft blended oil.
On the later engines, you are wasting money if you run any octane other than what it is tuned for, plus, you may even be leaving harmful deposits.

You can change back and forth all you want. There are few of the old PAO synthetics anymore and unless you are using Royal Purple or Amsoil, you're putting dino oil in it anyway. Yep, most synthetics on the market today are a Gp III dino. There is not any advantage to using any of them. They won't make the engine last longer, you won't get better fuel mileage using the correct viscosity, there is no more protection that folks like to expound on- it's all advertizing hype. As long as it has the correct Ford spec on the bottle, you can't buy a better oil regardless of price.

Going from syn to dino and vice versa won't do any harm at all. I would also suggest a site dedicated to lubrication like BITOG to help you with selection. They have tons of UOA's (used oil analysis) for Ford engines. For the most part people there will tell you to stick to a 5W20 oil and a Motorcraft filter for the best results.

I own a 2002 ford f150 with 86000 miles on it. I just recently compared the two oils and found that syentic was a lot better. The set up I used was Royal Purple and a k&N oil filter. The difference was night and day. With Royal Purple my truck ran better. One thing that I have done and recomend is if u use royal purple is also change everything else to royal purple.
