Running synthetic is a good choice. Not only does it extend your service intervals, it also gets rid of heat better than 15/40. I worked for Esso for 3 years and have been to a few trade shows and all the oil geeks say the same thing.
Not only that but turbo shut down time after driving is much less of an issue then it was with pure dino oil.
Not only does it extend your service intervals, ...
Disagree. I run synthetic but change it at 5K mile intervals which is actually 2.5K miles sooner than Ford recommends. Good, clean oil is particularly important to the 6 liter engine and IMO the additional cost is cheap insurance against oil related issues. Just my $0.02
I agree with cowboy on the clean oil aspect but also due to the fact that the 6.0's high press. oil system shears the oil. 5,000 miles/6 months is the limit that I will leave oil in and I also use the 5W40 synthetic.
Where are you seeing that, because according to my specs it's 18,000 for 5th wheel?
12,500 is where my little 2 horse gooseneck trailer maxs out(the one pictured with the tractor pulling it). That seems a little pathetic to me if that's the max tow rating.
The only thing that 12,500 could be a limit for is that would put me within 500lbs of the 26,000 weight would would be the max before needing a CDL(that would be "sticker" weight of both, not actual, however, "sticker" is what they go by if you don't have cat scale papers to show otherwise). Now there might be other exemptions that trump that weight limition(ag. products hauled within 150 mile radius from "home" etc), but that's if there is no other consideration, but weight.
Sorry, little disclaimer but that's conventional bumper pull towing. The limiting factor is actually the hitch. The factory Ford hitch is only rated for 12500 lbs. For 5th wheel towing, the numbers aren't all that impressive though. You may have a different configuration, but according to the GCWR ratings on pg. 16 of my Power Stroke Owners Supplement the GCWR of a 2006 F250/F350 SRW is 23000 lbs (all came with 3.73). If you have a DRW then it goes to 23500 lbs with 3.73 and 4.10's. 4.30 gears will get you the 26000 that you mention. The F450/550 is good for 26000 lbs unless you ordered the 4.88 gears with the high capacity trailer tow package. The max trailer weight is the GCWR minus the weight of you vehicle loaded up.
