I own a 2000 Ford Ranger with the flex fuel engine 3.0L. Anyone use STP Oil Treatment with their Full Synthetic oil or dino OCI's? Any benefit from using this product??

I wouldn't use STP. Too thick for one. Valvoline Synpower Oil Treatment is much better stuff, though also thick (not as thick though) and can use one bottle for 2 to 3 OCIs at 1 oz per quart.
I wonder if you have the old pushrod 3.0 or is it the new fangled 3.0. I have a pushrod 3.0 (called the Vulcan) and am running oversized oil filters (FL1A) instead of the spec FL400s.

Should be called "STP Customer's Wallet Treatment."
Get a good oil of the correct viscosity and you don't need to treat it with anything.

To follow up on Mr. Incredible's recommendation, I would highly recommend Maxlife. Maxlife has the lower zddp of all other SM oils, but adds 300 ppm of friction modifying and engine protecting moly, and includes about 12-22% PAO. I have had great performance with Maxlife including a grueling 5000 mile two-week trip in 100F weather throught the Rocky Mountains with no ill effects, no viscosity collapse, etc.
Ironically, my great grandpa was an auto mechanic and one of the things my dad remembers about him is that he didn't think that STP should be used in a non-racing application where the engine was rebuilt a lot or it would "gum" things up. Obviously, the product has changed over the years, but...
STP is good for worn out or loose tolerance engines that have been neglected and are not worth being rebuilt. Old beat up motorcycles fall into this category many times and a 1/2 bottle of STP with 40w or 20w50 oil will help restore some lost compression.Works great on old farm equipment, lawnmowers etc. But I would never use it on a modern close tolerance engine unless it meets the above criteria.
I think STP is pretty much old technology no longer really very relevant in the modern world. It would be okay for use in a worn engine where is there oil consumption and that is about it. MaxLife engine oil and various other high mileage oils would probably be better in a worn engine.
I think STP was fined twice by the FTC for false advertising. Think about that the next time you want to add some to your engine. I would be more willing myself to use Valvoline engine oil supplement in warm weather than STP.

Don't use it its #@$%!, just pour wax in the motor. years ago I purchased an old 67 mustang It had a transplanted 351 Cleveland motor in it, The guy used stp religiously, when I took the valve covers off I had to use a putty knife to scoop the gel off the heads, it gums up your motor, it will ruin a modern motor.
I know a mechanic who said he used to use it in his old gas tractors. said he "gained a gear" in power when using the stuff. attributed it to the compression gained from the thicker viscosity... I think anymore it has no real use. VSOT is a much better product if you want to feel like you are "beefing" up your oil with an easy to find cheap additive from the snake oil shelf. (there's only a few things on that shelf that aren't snake oil)
Good point all. I do have the vulcan engine with the push rod. I usually use Mobil 1 10w30 but sometimes use Pennzoil Platinum 10w30.
