Delo 15w40
What do guys think, I am not trying to start an oil debate, just interested in your thoughts.
I recently started using the Delo 15w40 my last oil change with the ususl MC oil filter. Prior to I used Rotella 15w40 and MC 15w40 with no complaints, I think both are good oils. The reason on switching was I read somewhere the Delo was a good oil and consumption was lower with our 7.3's
With the Rotella I would sometimes use 2 quarts between 5000 mile changes. With the Delo I only use 1 quart. I am not sure why this is, but I am happy with that.

I can endorse Delo as a good oil, I've used it for about 45 years, but virtually all diesel-rated oils will do the job.
I maintain one other 7.3 besides my own, and use Rotella in it with equal results.
Both of these engines are stockers, so I can't speak for high-performance oils in high-performance engines.

Welcome to FTE.
I've used Delo15w40, Rotella 15w40 and Rotella 5w40 synthetic. Haven't noticed any difference in oil consumtion or how the truck runs with the 15w40 in it. Big difference, however, with the 5w40 synthetic. Stars better cold, runs quieter, etc.
On that note, I don't think I'm going to run 15w40 anymore. I've had numerous cases of the romps lately, usually never happens when the temp is above 40 or so but I had it happen yesterday and it was 68 degrees.
