I'm assuming here, because i don't know much about 3116's but I believe those have EUI's in them, and I think the oils will destroy the injectors and their expensive cat parts. Older diesels with mechanical injectors are the way to go for running waste oils.
it is a all mechanical engine, I know cat has a 2 micron filter and not sure how that would work with wvo. I have sseen in other posts that wmo is a bad ideal in them.
a filter that small (m35 uses a 6 micron) your going to clog it right up. With my old deuce I would just dump the WMO and ATF right in the tank non filtered and I would have to change fuel filters every 3k miles. With a 2 micron its going to be more like 500 or less. The general rule is the 6.2 and the cat engines don't really like WMO too much. Yes it will run but what kind of other things are going to get hurt.
I know of a guy who runs this kind of oil through an old 7.3L Powerstroke (different engine I know) and it works ok. With the PS not being a "multi-fuel" it still burns it, don't know why the 3116 wouldn't but like I said with it not being the same engine you may get different results.
I've spent a lot of time looking at threads on other sites where guys run WMO and it really runs the gamut from guys that have had zero issues, to guys that are morons and have constant issues. There were a bunch of cummins guys taking pictures of their carboned up injectors, but I didn't see any injector failure complaints from the powerstroke guys. I believe the CAT shares more commonality with the PS than anything else when it comes to injector design.
I would only want to run 50/50 wmo diesel. I'm not trying to be a champion of free fuel...... I just want to drive my truck more for cheaper.
