Based on the tests I've seen I'll be switching to Schaeffer's 9000 Supreme on my next oil change.

Check out Bobistheoilguy.com. You'll find alot of information out about Schaeffer's Oil as well as most any other oil on the market. I know Schaeffer's is a sponsor there, but so is Amsoil and some others.

Here's a link to the Schaeffer's technical data for 9000 Supreme:

I have had great luck over the years with Rotella synthetic blend, not just with this diesel, but with my 95 which I slod with 224,000 miles on it and running strong. Also I ahve used synthetic fuel stabilizer on occaision when I have a couple of extra bucks in my pocket. les

Has anyone used Castrol Tection? I have used Castrol in my cars and motorcycles for years and when I got into my Honda 500 cc for an alternator/generator replacement at 80,000 miles the aluminum innards were as clean and shiny as the outsides, and the cars have never needed any teardown. My '82 diesel Rabbit got run into at 270,000 miles and always had Castrol GTX. That's my testimonial for Castrol, and would like to use their diesel product if someone else has tried it and likes it.

i personally would stick to rotella.
i dont mind changing my oil every 3-5k. gives me a chance to get a good look at the bottom side (ie. looking for leaks, worn parts, and ect.)

In all fairness, Rotella, Mobil, Castrol, Motorcraft, they are all good oils. I used to swear by Delvac in the Marine engines is severe hard going... But the truth is they are probably all good enough. Ford Australia is saying Castrol RX Super, even Castrol Tection Plus... In all fairness, I would not worry about which one I used anywhere near as much as HOW OFTEN I CHANGED IT!!!! :burnout

Severe work, like here in Oz, towing? Or severe work like in running big chips and street drags? I would change the oil closer to 3500 miles, and then I do not think it matters which of the good choices above... 5000 km here in Oz, not the Factory listed 7500 or the Factory listed 5000 miles. If it is hard going, change it more frequently, then the oil choice is not much to talk about of the above ones..

Regards from the Lone Ranger, changing oil since the 60's... Ha!
