I recently purchased my tour with 36k on it. The receipts show dino oil. Will changing to syn release deposits and sludge? So my real concern is: After I put Mobil 1 in it should I change the oil sooner the first time?

change it at 3k miles first time, should be alright. increase change interval a little every time you change after that.

i will (have clost to 90k right now, and just go the car 9 months ago). i want to do everything i can to protect the engine (especially in georgia heat, and the way I sometimes treat the car). anything that can possibly make the car last longer is worth it to me. and since I change it myself, the cost comes out to around the same as quick lube cost. A smoother idle can't be bad for the engine at times other than idle, so I figure that's a good indication that it's helping. (Synthetics used early enough can help to stop leaks (smaller molecule size, seals better) as long as you have lower miles, so yes it can make an engine last longer).

Assuming proper oil changes, the increase in engine life between Syns and Dinos are practically undetectable. Some of the results I have seen are so similar that no clear advantage can be given to either.
As far as the smooth idle goes, I suppose if you can justify spending 2x as much to get a smoother idling engine that lasts the same amount of time, so be it.

I know what your saying D, especially the above statement about 100K, but check this out. I remember talking to my ex-boss and he and his buddy w/ a 9 sec T/A tore the motor apart after a couple seasons. Upon inspecting the main bearings my ex-boss, an "old schooler", was stunned...no wear to be found  I feel running Mobil 1 is insurance for your motor, whats a couple extra bucks? Someone in one of the previous post was talking about how expensive Mobil 1 is, better get out the WD40 because someone is SQEAKING

Synthetics have never shown a definitively longer engine life. Basically, if you changed your oil religously at 3k miles using Dino oil and had an identical car and changed mobil 1 every 5k miles (I'm being outlandishly conservative with the intervals), no testing has shown the car using Mobil 1 will have longer engine life. I wholeheartedly disagree with your comment that it will definitively last longer. It may or may not last longer. If you don't mind spending the extra money to get piece of mind, so be it.

That would be the case if there weren't such things as temperature extremes. Ever see dino oil at -20F? You may as well not have any oil in your engine at all. You can't honestly say that doesn't affect the wear on your engine. Synthetics (and some blends) will flow very well at -20 and below...that is just one of the many benefits. In one year, I spend $66 on oil and filters (2 filters, 7 qts oil)...and that's 24k miles. Change your oil every 3k, and you'll go through 7 additional oil changes (42 qts oil, 7 filters) for a total of around $84. Then add the price of labor for each change. I change my own oil, and my time is worth something. Yours may not...that's for you to decide.
I'm not sure which kind of synthetic you are using, so it's hard to make a comparison but lets use absurdly short intervals for comparison sake and say that every 3k for dino and every 5k for Mobil 1. I drive 40k per year on average and my vehicle uses 5 quarts of oil.
Synthetic (Mobile 1)
5 quarts of oil on sale at 3.75/qt......18.75
Filter: Mobile 1 filter................11.99
1 Oil change...........................~30.00
8 oil changes per year................$240.00
Dino (Mobile 0)
5 quarts of oil on sale..................4.99
Motorcraft Filter........................3.99
1 oil change.............................9.00
13 oil changes per year................$117.00
Now lets try something more realisitic with 6000 mile changes on the dino oil and in your example 12k intervals with mobile 1 (or whatever you use)
Dino=7 changes per year.......63.00
Syn=3.3 changes per year......100.00

Now tell me.....How is dino oil cheaper? 
Any questions? Or would you like to manipulate the numbers again?

Absolutely. 5000k on dino oil would be fine, so synthetics should cause no problems.
Same case for me. Just switched to Mobil1 at 39K miles. Also switched from Fram to Motorcraft filters. Will the filter last 5000 miles? My engine is noticeably smoother at idle.

I think you need to use the same filters in both comparisons since we are talking about the cost of Synthetic oil.
So in the case of the 3K vs 5K intervals you are talking $117 vs $176, using the Motorcraft filter in all cases.
And looking at 6K vs 12K the costs are $63 vs $73.60
Still convetional oil is cheaper, but not drastically.
Use the Mobil 1 filter in both cases and the cost to use conventional oil at shorter intervals is greater than to use synthetic.
Of course, any scenario can be crafted to make any choice appear to be the best, cost wise. So buy what makes you sleep better at night.

Good point, Tony. I guess I should have left all else equal.
Although, I guess if someone was going to spend extra money on oil for piece of mind, they probably wouldn't "skimp" on a filter for the same reason.
