I just used the gold stuff again. I don't mind changing it every 100k. There is a new (red I think) one that's supposed to be good for 300k if changing it every 100 is too much.

Gold is a good compromise between the ELC and Green. It has some silicates, but they do not need checked & maintained like the old green. You can go with the ELC as well, but it's a little more expensive and requires good flush before hand. Your choice.

It's available in stores. It's the ELC Joe was talking about. Maybe he can tell you where he got his.

Check with Napa -- they should have it. Ask for Final Charge in concentrate -- it's the same as Rotella ELC. You'll need four gallons of that and about 20 gallons of distilled to flush out the old stuff. Save enough of distilled after flushing to top off after dumping the four gallons of ELC in (about 2-3 gallons).

I was thinking of going with the Rotella if I can find it locally. So will I need to do a good flush to use it also?

Just drain, fill with distilled, heat up to temp so 'stat opens, let cool, and repeat until you get down to 3 gallons of distilled left or the water coming out is perfectly clear. That should get it clean enough to add the ELC.

Also, you can get the 203* stat and pull the old one out first to speed up the flush process. You won't have to wait for the engine to heat up between cycles. Put the new stat back in on the last drain and you should be good to go. You can also drain the block in the back if you like, but some folks have had equally good results without going though that.

I have heard about the 203 thermostat before. Does it fit into the stock housing or do you have to by a new one?

You can reuse the stock housing if it's in good shape. If not, get the billet one from DieselSite.com when you order the stat. As long as you get the long stem stat, it's a direct replacement. DieselSite will send you the right one.
