Diesel additives for DPF/EGR longevity

[Thermo1223]

I wish all turbos were water cooled….. The MB OM642 in the USA is oil cooled only, they are water cooled in Europe. I have one in a 2013 Mercedes GL350 and I cool it down when I come off of the interstate for 2-4 minutes.

That's asinine even for MB, hell that's something VW would do.

the dpf on the semi trucks at my last job didnt make 100k.

Sounds like there was good reason for Chevron coming out with the Delo 600 ADF. Too bad it's only available in a 10w-30 though.

How much prolonged idling did those trucks do?
How many short trips?

Good question, Throwing in another question w/yours here.

@Chris142 Does CA have more smog requirements, in addition to Federal, on these trucks to cause a lower lifespan for the emissions equipment?

Our busses have up to 500k miles. The vast majority have a functional DPF. The oldestr ones are most likely to have a dpf warning on the dash, but even that doesn't mean they smoke.

Day cabs so very little idling. only idled to load or unload equipment or to build air first thing in the morning. Nothing like an otr truck that sits 8+ hrs a night idling.

Most jobs are an hour away or more on the fwy.

Not that im aware of. There is a new law coming out that requires the trucks to be smog tested every 3 months though .

Thanks for that. I know there was some sort of "Phase out" plan a few years back b/c I was seeing all sorts of older trucks being sold out of CA.

And 15w40.

hmm, I must of missed that grade. I just looked it up on their website & there it is a 15w-40 600. Thanks for adding that information.

Am I the only one that has used and likes LM's DPF Protect?

Amazon carries it, as does IDparts.com and others.

I'm a semi mechanic. I work on natural gas and diesel semis. The best thing you can do for a modern diesel is not let it idle for prolonged periods. That includes warming the engine up, too. The old herd thought of needing to warm up a diesel won't gain you any miles. It will however net you less miles on $$$ components.

That is true do not idle a diesel because it will soot up the intake system and other items. I have a 02 7.3 with no emissions and 41K and the only idle I do is just to cool the turbo down after pulling my utv trailer on the highway.

Used to idle my diesel until I found it had enough heat to keep the windows clear. It never did soot up anything to the point of noticeable differences. And it ran at 120k miles and year 9 like it did it's first year. Then it took a hit that totaled it.

if the dpf was in regen, and I had the option to do so, I left the engine running while parked until it was finished. A regen took 10 minutes start to finish.

There is a YT video where Lake (a guy) had several fuel additives tested at a lab stat does fuel testing. I think OptiLube XPD and Archoil were the best. They were rated for increasing cetane and lubricity. Also mentioned to use the specified dose. Don't think if some is good, more is better.
