gryffinwings Posted March 13, 2014 Report Share Posted March 13, 2014 I was wondering if anyone was using HDEO (Heavy Duty Engine Oil) oil like Chevron Delo 400 or Rotella T in there 720? Curious if it helped out with seals, cleaning and noise, basically want to know if it helped with the overall running condition of the engine? Also how often do you change it? I am personally using Chevron Delo 400 LE 15W40. But haven't really started driving my truck much til I get it registered by next week. Not to mention I had to fix a few things first.

Yeti Posted March 14, 2014 Report Share Posted March 14, 2014 I've heard quite a few people recommend Chevron Delo 400 for older engines based on its additives. Apparently it's better at protecting our cams from wear as opposed to most regular oil for modern engines. Quote Link to comment
datzenmike Posted March 14, 2014 Report Share Posted March 14, 2014 It's for the extra ZDDP in it nothing more. It's slightly more detergent than gas motor oils but if your motor is in good running order this is fine. So what is HDEO? Quote Link to comment
Guest Rick-rat Posted March 14, 2014 Report Share Posted March 14, 2014 Highly Diluted Engine Oil? Hemp Distilled Eco Oil? High detergent engine oil? Quote Link to comment
Yeti Posted March 14, 2014 Report Share Posted March 14, 2014 Heavy Duty Engine Oil. They are formulated for use in diesel engines, but many are approved for use in gasoline engines as well. Quote Link to comment
Guest Rick-rat Posted March 14, 2014 Report Share Posted March 14, 2014 Not everyone knows what your acronyms mean, especially old farts like me, I don't text because I can't stand all the abbreviations I went to a briefing at work that took 3 days. Most of the people that were there had been to these before and was pretty boring for them. they were throwing out acronyms, and I had no clue what they were talking aboot. At our first break I asked the guy in charge if he had a list of acronyms because I had no idea what they were trying to say. Once he gave me the list I was able to keep up, because it was my first time. I had to go to these lectures 3 times, after the first time was able to sleep through the rest like the other experienced guys did Quote Link to comment
gryffinwings Posted March 14, 2014 Author Report Share Posted March 14, 2014 Sorry about the confusion, I figured it would be more well know. When I mean high mileage, yeah, I'm talking about up there closer to the 200,000 mile range. Quote Link to comment
datzenmike Posted March 14, 2014 Report Share Posted March 14, 2014 Over the last 20-ish years there's been a switch to roller rocker cams that do not need as much anti scuff ZDDP in their oil formulas so it has been slowly dropping in content. The problem is our motors have not changed an need it so we have to look for alternatives that still have this higher level in them. These 'light' diesel oils seem to be the answer.

ggzilla Posted March 15, 2014 Report Share Posted March 15, 2014 And yet Z-series engines do well with regular oils. Only have heard of problems with aftermarket cams. Quote Link to comment
