I finally took the plunge and bought a new 06 4x4 Toy last sunday, has the V6 4.0 236HP motor, any ideas of what to run for oil in this new rig, I tow a 1,000 boat some, small loads 600 lbs or so. Been using 0-40 Mobil 1 at 10K changes in my old 88 toy 4x4 with great success for 75K miles, but warranty on this new truck will limit me to a 5-30 wt with 5K changes, now at least for the first 50K till warranty runs out. GC? EPM1? regular M1?? Thanks.
