Synlubes... I do have the Jeep Liberty CD from 2004 to 2006 and in the 2004 they have the VM motori Liberty CRD and they recommend 10w-40 for the CRD for the 2.8 and 2.5 and now they recommend 5w-40. You are right. I am using the 5w-40 for now but when the supply that i have end i will go for the syn 15w-40 because there is no blow by and beside i live in a warm state.

Synlubes... Yes! If the engine is good for a Tractor in Italy, it should be excellent in my Libby.

I don't think you should make a direct comparison about the 2.8 CRD and a tractor. There are still older type diesel engines with less power offered on the EU market. Several friends are considering stepping back to get less trouble and smoother ride because of the extra difficulty when using the manual shifting. People complain that they stall too often when they start from standstill. Another aspect of this engine is that when the driver follows a conversation with his passengers on a fast portion of road, he often forgets to use the upper gear (6th in manual) because he needed the presence of torque a few seconds ago and this forced him to downshift. Down goes the mileage you paid for

How do you calculate your fuel mileage (mpg)?
I have a 2005 and the best I have gotten is 23mpg. Most fillups are 15 gallons or more traveling 300 to 330 miles. last fill up it took 15.7 gallons and I traveled 321 miles. This is the usual 20 to 22 mpg. Mostly highway driving with the cruise control set around 73mph at 2200rpm.

I wouldn't think you would have any problems pulling the Casita and doubt you would see any difference in RPM.
I'm still getting just over 20 mpg at 56-57 in 4th gear and around 16-17 in 5th at 65, I can live with this.

Until DCX and V.M. Motori clear their engines to run with a 5W-30 in the crankcase, I will continue to use either the 5W-40 or 15W-40 synthetic oils. I do not feel comfortable tempting the fates.

That is kind of low FE in my view, but I tend to drive more gently. I get between 21 and 23 MPG when I commute and 28 and up on long trips. I generally keep the engine chugging along at about 1800 to 1900 RPM or about 62 MPH.
