I stumbled across an HDEO offering, Delo 15W-40 600 ADF which claims an "ultra low ash" technology.

How does this differ from a standard CK-4 HDEO and are other oil companies following this trend? I'm curious if this is an oil that could see dual use in a diesel and gas engine, the latter including (T)-GDI engines that would benefit from a low ash oil.

It has been out for a bit now & it was made to combat big OTR trucks emissions systems that would cause plugging earlier causing big $$$ in repairs. This product claims to extend the emission system life while maintaining wear control. In my opinion it's for newer trucks though (obviously w/dpf) but I think if you're wanting to use it in a gasoline engine it should work okay. The biggest reason would be increasing viscosity grade w/lower additives as you're implying. I could see one running this in an oil burner/fuel diluting engine among other reasons.
 
Foxtrot is using it in his fleet now so must be working. Main difference being no metallic additives to poison dpfs.
 
Abandons ZDDP for moly. Not really being marketed at retail. Chevron is mostly pushing it through fleet distributors. Can order gallon jugs via amazon, walmart, etc. They also offer 10w-30.

UOA from an L5p being run by someone I trust. He's from Canada and wishes 5w-40 was available. He says wear metal rates are very similar to his prior lube (Delo 400 5w-40) in the same motor. I'm considering going to it. I'm sure Chevron did their homework.

Some labs struggle with UOA because the chemistry is different. Chevron has a lab you can use.

Seems like quite a departure versus what we're used to in an HDEO oil. What's up with the Potassium?

Mg and Ca seem on the low side as well for a modern oil, perhaps the heavy dose of boron and moly make up for that? Is boron a detergent or anti-wear additive?

Too many substantial differences in additive chemistry for me to be a guinea pig by using it in a modern T-GDI engine, but I'd love to learn more about this stuff.

I’m not sure there’s any real reason to use it in a gas motor or even a pre emissions diesel. It’s not dual rated and not likely to be. When Sulfur got removed from fuel it opened the door for some of the changes you note.

I’m sure Chevron did their homework and there’s more of it in use than we might realize at BITOG. I’ll bet the future will hold similar formulations from Rotella, delvac, etc.

It’s extremely different than any other HDEO additive package. Chevron has done their homework on it. Under development for over a decade, soft launched at the end of 2019 for basically big fleets. Then circled back at the end of 2022 for more of a “hard” launch for retail markets.

Essentially going to be the future of HDEO engine oils in 2027 and beyond for whenever we get Tier 5. Or so they’re claiming. They’re also claiming a lot of things… increased fuel economy, lower wear, longer DPF life, etc. etc.

I am running it in 8 brand new PX9 engines currently. We will be double sampling, through Chevron and an independent lab for analysis.

It is priced… very high. It’s in the full synthetic price range for being a synthetic blend. Which makes it hard to swallow for a lot of customers when it’s priced significantly over the rest of the synthetic blend HDEO world. Will it be worth it? We will see.

They have no interest in licensing out the technology for it. So someone would need to independently develop another formulation to license out.

Thank you! I've been a big proponent (and purchaser) of Chevron motor oils over the years. Sad to see they occupy so little space on store shelves, but they seem to be doing good in the fleet market. If I ever get ahold of the Delo 600 ADF, I'll run it in one of my older vehicles along with a UOA.
 
I wonder why this isn’t a full synthetic oil?


No need. Full synthetics are pretty silly in the fleet HDEO world. Soot load kills the oil far before oxidation does. And fleets either plug their vehicles in, or just don’t shut them off. If you’re worried about cold flow on start up. Which in a large part of the US, isn’t an issue anyways.

It’s primarily designed for the OTR class 8 market. Which… just doesn’t shut off. Or the rare times they do, it’s plugged in.

The whole “has to be a full synthetic” crowd, is a PCEO thing. Not an HDEO market issue. Very, very, very little of the HDEO market is full synthetic.
