Did ibf go with the synthetic?
Not trying to crash the party but... ibf asked about switching to Mobil 1 and we didn't hear back one way or the other- My $.02 worth: Go with the Mobil 1 synthetic. I run it in my 6.0 PSD and very impressed with the results- Increased mpg, easy/smooth starts, etc. I like it!

had to finish up the case of conventional oil that i already had. switching to mobil 1 synth on my next oil change. going to try that for a couple of runs and see if it leaks any. if it does, its back to conventional.

i typed a reply a while back and i guess it didnt send, since i dont see it in the postings. talked to my dealer and he said try synthetic for two oil changes and see if it has any leaks. if it does, switch back. if not, keep using it. got 1500 miles till my next oil change, so i should have some results fairly soon.

Thanks for posting in ibf-
And good thread too! Always interesting to hear the response to switching over to synthetic. IMO, as long as there is relatively low mileage on the vehicle, I have never heard of negative results from using a good quality synthetic oil.

This may or may not get some action. We just changed from the factory oil in my 05 power stroke to synergyn 3-30. "pause" I was able to talk to my dealer face to face and had any ? answered. Plan to run extended change with filter and analisys done at 7500 miles. I expect Oilguard's system to be here on the 17th and will add it to the best truck I've owned. (2005 F-250 Crew with the 6.0)

switch to mobil 1
Your engine will not start leaking from switching to mobil 1 at 20,000 miles. I just bought a 2002 XLT with the 4.2 had 24,000 on it and switched and no problems. And as long as the oil meets what Ford says that engine has to have in it, which Mobil 1 does It won't void the warranty. I get a real good laugh at the oil section on this site. Dont get me wrong I have owned trucks that I have ran good old Castrol in from day one till i sold it 170,000 miles worth and I have done the same with Mobil 1 for 180,000 on my wifes car, My veiw on the difference is simply from ovservation is the engine that ran the synthetic oil was spotless inside. The dino engine not filthy but a difference of cleanlyness. and for me I will spend the extra money and not worry and if i dont feel like changing the oil right on time no big deal.

i say switch. i change all my vehicles over to synthetic if they seem to be in great condition. The reason for leaks with synthetic is due to the cleaners in the oil. it breaks up deposits and some deposits are blocking would be leaks. i like the ability to go longer in between changes...although i still change at 3000 miles or close to it. i'm **** i guess. i think dino oil is good enough for most but i figure why skim on the engines life blood. save about 60 bucks a year....

There's evidence that extended drain intervals actually reduce wear on an engine and that the majority of the wear occurs in the first 3000 miles or so and drops off after that - to an extent. I've heard that Ford has actually done studies on this and concluded as such. I haven't seen the hard evidence from ford themselves but the extended drain studies on neptune suggest the same. So, it would seem that people doing 3000 mile oil changes are actually making their engine wear out faster.

This is a quote from the synthetic oil life study.
"The solid lines are the standardized cumulative totals of wear metals in parts per million for iron, copper, and lead. The shaded lines are the standardized totals of wear metals in ppm per mile -- in other words, the shaded lines represent how quickly the wear metals accumulate as compared to how quickly the miles accumulate.
While the wear metals all accumulated steadily over the course of the test, the highest concentrations of accumulation per mile occurred in the first 3,000 miles of the test! From the 3,000-mile mark all the way to 18,000 miles, only lead showed an increase in per-mile wear beyond 3,000 miles. Yet even with an increased wear rate, lead wore the least in terms of absolute wear. For iron and copper, the longer the oil remained in service, the lower the wear rate got.
In case it isn't obvious yet, this means that the most wear occurs in the first 3,000 miles."
I tried to find info that Ford may have on the web from their studies but searching for anything to do with extended oil change intervals just brings up a bunch of Amsoil links.

Ford +extended +oil +change +wear -amsoil
The -amsoil will weed out most amsoil links.

My theory why synthetics "cause" leaks in older cars, and I have seen it happen, is that synthetics flow better cold, before worn parts have expanded to operating clearances at normal operating temperature.

Hmmm, not sure, but I thought Group III had good solvency due to its level of purification. Anyway I put Synpower in wife's Aerostar last Sept. Now about 1500 miles and the blotters have been coming up pretty dirty. My guess is some cleaning is happening. Also, too early to tell, but looks like consumption may be going down as it cleans. Oh yeah, I did also put 4 ounces Redline oil in, but would that really help clean things up at that low level.
