I sent you an email with a writeup on break in that one of the folks contributed earlier. I hope it helps.

I have not quite 500 miles on mine but we have reservations to go camping this weekend and it's too late to cancel. It's an '04 F350 cc dually 4x4 and will be pulling a 34' 8500lb. travel trailer on mostly back roads on this trip about 60 miles or so. I'll probably have 500miles on it by the time we leave. do you feel it will be ok or am I setting myself up for something later. Thanks for any help. Steve
Is the total number of miles you are goint to tow this trailer...60?
This might seem weird but....is it falt pulling or.....or....

Thanks SBV, alot of reading but I think I got it. I don't know where you guys get all this good info. but I'm glad to find this site.

Tim, It's about 60 mi. one way. I'll leave friday evening and come back monday. Just a short get away. It will be mostly flat ground maybe a hill or two but no mountains until our october trip. There will be alot of stop & go and turns this time though.

Thanks to both for your replies, any additional info. will be greatly appreciated. I want to make sure I treat this truck right and start off on the right foot after all I went through with the last one, but I can't afford to cancel this trip either because I can't get my money back. Thanks again, Steve

Anytime ridn98hd. That is what this site is all about. I got that info from another on this site. Some of it is worth saving and sharing. Get to know your truck. The more you know the better off you will be with it.

Keeping this in mind, when would be the best time to switch to synthetic oil? I suspect synthetic oil would resist "oil glazing" better than dino oil. Especially if towing with low miles on the engine. I dump the factory fill at 500-1000 miles and refill with dino. Next oil change is 1500 miles later and synthetic is used from there on. One school of thought is, if you use synthetic in a new engine it won't break-in properly. But, GM uses Mobil 1 in the Corvette as factory fill.

Some say the first and some think the second is the way to go.
I installed oilguard and synthetic at the first change.

I don't think you will do any damage switching to synthetic early on, but it might take your engine a little longer to fully break in. For comparison, Cummins recommends waiting until 20K miles before switching to synthetic.

Question RPM range while breaking in a PSD? 500-1000 mile break-in

I've been reading the forum's the best I can about the techniques of engine break-in. Parking lot driving, varying rpm's, no excessive ideling, the do's and dont's, and so on. Applying the varying highway speeds technique hasn't done much for me, 55-65mph seems to be the range, which only gives me a change of 200 rpm or so. 70mph is hard to come by with traffic and the occasional Oregon State Trooper (55mph limit in urban areas).

What I'm wondering is, while on slower speed country roads (40-50mph) without a load, should I be shifting into 3rd gear to get my rpm's up? At 40 mph the tach will set at just around 2500 rpm and the engine temp needle raises a little but not much.

Is this a safe and/or useful technique for break-in?
What would the ideal peak rpm be?
What duration before bringing the rpm's back down?

Break-in Load

How much of a load at 1000 miles?
My options include:
- A garage full of stuff to storage?
- Load of yard debris to the dump?
- Tow a small vehicle on a trailer?

When would you suggest trailiering a vehicle behind it?

How to break in 6.0L

[QUOTE=Tadashi]yeah that is the article I read but was not sure what moderate loading meant. I will be hitting that 1k miles soon and want to ensure all is good before my move from KS to TX.[

When I took mine for its maiden voyage it had 519 miles on it. We hooked up to our 12,800 5th wheel and went to Florida for Thanksgiving. No problem other than I felt the TorkShift was hunting more than I would have expected. Since then, we went on trips to several areas of hills and valleys and another Florida trip last week, and all seems well, including the shift hunting. It appears to be learning my habits.

Reading the "break-in" procedure, it left out a number for peak rpm. What would be acceptable for "near red-line" rpm's? I have been following the procedure by accelerating in the lower gears to apprx 2500 - 2750 rpm and then letting off the accelerator until nearly stopped. Is this correct and how many times are recommended?

One interesting observation is when I had my Differentials re-geared and rebuilt the Shop made a strong sugestion to not run the truck for more than 20 miles without stoping to let the Differentials cool off for the first 100 miles. I would think the same recomendation would hold for a new truck.

That was for my 93 Bronco, I just bought a 2006 F-350 PSD two weeks ago and I have 400+ miles on it.
