1. all automotive engine oil has detergent (as already stated)
2. dealer cost is probably higher than a local shop
3. 4.6 is designed for synthetic.

The technical advantages of synthetic motor oils include:
[ul][*]Measurably better low and high temperature viscosity performance[*]Better chemical & shear stability[*]Decreased evaporative loss[*]Resistance to oxidation, thermal breakdown and oil sludgeproblems[*]Extended drain intervals with the environmental benefit of less waste oil created. [/ul]

waste of money.....rear end fluid lasts 100,000 miles. mine lasted that long with no problems.

I change my own oil, use synthetic, and K&N oil filter every 4000 miles. Take my used oil down to my local Advanced Auto Parts store. I just feel if I'm not doing its not getting done right.

Nothing wrong with having someone else do it if thats your thing. I actually take my 2001 E46 BMW to my BMW guy (not the dealership) because he charges me 55 bucks which is really only a few bucks more then what it would cost me and he does the work...kind of a no brainer...however I know and trust the guy as well.

local shop like a trustworthy service station...not like jiffy lube or some **** like that

+1 only thing is our shop is the ford dealer we know like everyone there. When your parents have to buy like 4 work vehicles a year they tend to get to know you. And to who ever said that you have no idea of what they are putting in thats just stupid the dealership will always use motorcraft on everything.

Parts shops are required by law to take yoru used oil. save a gallon milk jug and take it in to them, they will recycle it.

There is no reason to wait a long time to let it all drizzle out.. there is still giong to be used oil in there. Its just not that big of a deal, a little bit (1/20th of a quart or some crap) is not going to effect an entire oil change. if its that bad and your oil is that dirty, change it more often!

And USE SYNTHETIC. the first mod (yes, even before gears lol) everyone should do is swap ALL fluids to synthetic. My car takes almost x2 as long to heat up with no change other that full synthetic motor oil.. its simply that much better (less friction).

If your car uses oil when using synthetic, its already screwed anyway. the reason that syn will sometimes use more is the shape of the molcules (SP FTW) is more consistant, smaller, and round, unlike dyno oil which is non consistant and larger/not round. Syn will leak etc if you alraedy have engine problems, but not if you don't.

The entire thing with syn causing problems was only back in the day, cylinder rings were designed to expand the first few thousand miles, and the reason they did so was additives in the oil. the syn didn't have it, and it was causing problems with engine break in. this doesn't happen anymore (they do the rings differently) so its no longer a problem.

Synthetic FTW. Nothing else will ever touch my car again. Have the dealership swap all fluids to synthetic, or better yet have a oil change place do it (stealership is gonna rape ya).

My thoughts as well but thanks to all who replied both neg and pos. I am not the most mechanically inclined person so I choose to have a local dealer do my oil changes. I would never use a Jiffy Lube or any BS shop like them.

I do now how to fix computers which I could sit here and say how easy most things are to fix on them and you would have to be an idiot to pay someone to fix but I love the money.
