Driving across the country soon.

What should be on my list to change/replace? Please list even the obvious. I need to order today.

(procrasination). It for a 90 300D 2.5T w/ 105,000miles. Thanks.

Air and fuel filters, complete oil and oil filter change, tranny fluid and filter change, and radiator flush and fill. Also flush the brake system, and check or change the rear diff oil.

Diesel purge would be good as well. Check all hoses and fuel lines for leaks, and check the belts.

Which rear diff and tranny fluid is recommended? My 2.3 16v loved Redline, but I can't recall which Redline products...

Any good name brand should be fine. A lot of people swear by Amsoil. Rear diff is typically heavy gear oil, so any good brand should be fine.

Tranny needs to be Dexron III or IV.

True synthetics, although expensive, offer the best protection from wear.

Are all of the fuel filters e.g Mann, Mahle, Bosch, etc equal?

I prefer the Mann filters personally. Mahle is good also, and so is Hengst.

Lastly, preference on engine oil?

Currently I run conventional 15w40 Rotella or Delvac or Delo, whick ever is on sale. I plan on going synthetic using the Mobil 1 specifically for the diesel.
