'96 XJ 4.0, just over 90000 miles.
I recently emailed a Maine Amsoil dealer re:switching to Amsoil at my next oil change (coming up in about 1000 miles), & this is his reply.
----------------------------------------
There would not be any problem switching to a synthetic. I have switched many vehicles, some of them were over 100,000 miles at the time. The need to use Amsoil's Engine Flush* at the time of switching is very important. The reason being that it removes sludge, carbon deposits, etc. which could be a problem if not removed.

Synthetic lubricants clean the engine much better than petroleum lubricants, and the synthetic would dissolve the old deposits. Therefore I recommend that you do flush the engine to avoid future problems.

Longevity and fuel economy for the vehicle is best attained by using synthetic gear lube, and transmission fluid as well as engine*oil and filters. I recommend that you order several extra quarts and an extra filter to have on hand. This order reflects only what you would need for the first change.
ASL-QT** 5W30 Motor Oil*(6 qts.) $5.85 per qt.*** 6 x 5.85 = 35.10
SDF-42** Oil Filter* $11.55
AEF-CN* Engine Flush** $4.75
Maine Sales Tax* $2.57*
Shipping* 15lbs.**$7.75*
Total Price* $61.32
----------------------------------------------
Now I know from reading this forum that a synthetic ATF is not recommended (moot point anyway since I just had my ATF flushed/refilled & I'm not spending that much money again anytime soon), but that synthetics are good for diff/T-case.
My questions are: (1) Is the engine flush stuff he recommends a good idea? (2) Is there anything to be gained from switching my brand-new diff/T-case fluid to synthetic at this time & how much is a garage going to charge me to do that at the same time they do the oil?
I live in a cold climate & I have no garage; I'm interested in nothing but longevity/longevity/longevity. I don't mind spending a little more time & money if it's worth it but I don't have money to burn. Ive heard nothing but good things about Amsoil for years: is it really enough better than, say, the Castrol 5W50 Eagle uses year-round, to warrant the trouble of getting it? (Is the Castrol synthetic too, BTW?)
I will follow the board consensus here so help me out.
