Does anyone have proper break-in advice? I've heard many different opinions on the matter. Just bought the 5.7 double cab

First truck i bought in 84 or 85 I did the full break in, I did get over 250k miles out of it.

But since then I drive them home the way I 'll drive them every other day and to me it doesn't seem to change a thing, although I only keep them to about 100k before selling it.

Some one on another forum said he worked at the San Antonio plant and that they use synthetic in the engines.
