Just wondering if anyone uses synthetic oils in their tow vehicles, and how you like them. Anyone care to elaborate on your use of them? Are they all that?

Using synthetic in front and rear diffs. Seems like the place to use them, NOT using in engine or trans.

Installed a larger trans cooler and am using amsoil in the trans. Runs cooler than before I switched. I think 2000 and later gm's have synthetic in the diffs.

My entire truck -- engine, tranny, tcase and diffs -- is running Mobil 1. Heck, even the grease I use is Mobil 1 synthetic. Does that tell you how I feel about the subject?

Mobil 1 used since 1983 in all lubrication applications. Engine Oil, Grease, Gear Oil, & ATF - PSF. I let the truck tell me when it needs the engine oil changed. My crankcase holds 6.65 liters of oil. I also have used AC Delco filters and Mobil 1 filters.

I wouldn't use any other type of lube if it wasn't labeled 100% full synthetic.

Motor oils in general are changed to frequently as it is. But to each there own as they say.

I talked to my dealer about running Synthetics in my TAHOE. They basically told me...NOT NECESSARY. I changed all the fluids with regular oils for it's 30,000 mile maintenance. (diff's, transaxle, engine)

Still undecided for now.

Amsoil all around for me. Most important for the transmission cooling. I have used it for 25 years and i don't know how many miles, alot. I just like the extra 20-30 degrees drop in the trans temp.

DC recommends synthetic in the diffs when towing, so I use there, but not in the trans or engine. Might try soon.
