amsoil or other recommendations.

Beginning of 2019, I'm going to be travelling from PA to California. I was thinking of switching to Amsoil for a longer lasting oil, from Castrol Edge. Is this a good thing or does anyone have another recommendation. I'm going to be changing the differentials also before I go, so recommendations would be great for that. I'm pretty much driving nonstop, so looking for the best. I've always seen great advice on here on other things I have done with my 06 EB, looking for more!

Amsoil is good, but any major brand full synthetic would suffice.

I've always liked amsoil it was one of the first synthetics out there lots of experience

imo, Amsoil is the best followed by Mobil 1 (or LE for gear lube) but really, any synthetic is better than no synthetic.

The transmission would have the most to gain from synthetic oil.

I have been using Amsoil for years now in my 2006 eddie bauer 4.0L, as for the engine been using
Amsoil SAE15W-40 premium heavy duty Diesel & Marine. now at 162,000. miles and engine still running strong, No timing chain issues or other problems YET. I'm getting about 22/23mpg highway
and 16/17 locally. Transmission, transfer case, differentials all amsoil.

Amsoil is the best, and if you have the time to replace many of the fluids, join for $15 and buy what you can with no shipping costs, just taxes. I love their Severe Gear for diffs, and the ATF, engine oil, PS fluid etc.

I use the $5 a quart Amsoil now for my "old and need rebuilt" engines, or the best synthetic deal under $25 a jug from Walmart or Amazon. I just got some Valvoline for under $22 last month. It makes no sense to buy the $9/quart top Amsoil line for a 200k engine you're going to replace soon anyway.

Most synthetic gear oils are near or over $20 a quart, the Severe Gear is about $13 each, depending on which viscosity.
