Ok peeps, so my 30K service was just done. All fluids (except radiator coolant) that were changed were flushed out with new fluid, hence the volumes quoted are the total for flushing and replacement. Here are the details:
-Engine oil: Amsoil 15W-40 Synthetic . 2 gallons used
-Radiator coolant: Castrol Heavy Duty Coolant and Redline Diesel Water Wetter. 3 liters coolant by 3 oz water wetter used (70-30 ratio instead of 50-50)
-Transfer case and PS fluid: Amsoil ATF Synthetic. 4 quarts used
-Front and rear diff fluid: Amsoil Severe Gear lube 75W-90. 3 quarts used
-Brake fluid: Castrol Heavy Duty brake fluid DOT4. 1 quart used
-Air and fuel filters changed (OEM)
-Inspected both drive belts
-Inspected both timing chains
Was going to change Transmission fluid as well but the firm said that the tranny fluid was as clear as that in the bottles I brought

so no need.
All fluids came up to $2600 (note please that I have 12 quarts of Amsoil Synthetic ATF remaining as I did not change the tranny fluid. ) thanks to
GEAR HEAD for all the Amsoil stuff; great powerseller, always goes the extra mile to facilitate his customers’ needs
Service cost was $2036 (inclusive of OEM air, oil and fuel filters).
van wukkin sweet and quiet
