Why DIESELS Hold More Oil

Diesel Engines typically hold much more engine oil than a Gasoline Engine of comparable size. Diesel engines are physically larger, and do require additional oil for cooling, but that's not the main reason diesels need more oil.
Diesel combustion produces soot. It's what makes the exhaust smoke, and engine oil, so black. Soot is too small [sometimes smaller than 2 Micron (1 millionth of a meter)] to be caught by the oil filter, so it remains in the oil until the oil is changed. Bypass filters can't even catch all of the soot. Diesel engine oil has a lot of dispersant in the additive package, and this is what keeps the soot particles from sticking together and forming larger particles that can cause engine wear. But those dispersants can only handle so much soot before they become ineffective. So, the more engine oil you have in the crankcase, the more soot that can be absorbed before you need to change the oil. So the higher capacity is primarily needed to have an acceptable oil change interval. And that's the science.

The only diesel engine that doesn’t hold significantly more oil than a gasoline counterpart is my little Volkswagen TDI, it’s a 1.9 liter engine and takes 4.8 quarts every oil change. While my 7.3 takes 15 quarts every oil change, and my wife’s 3.0 ecodiesel takes 10.5 quarts every oil change.

[@freedomworx]

I like your style. I have a 7.3L Excursion and I used to have a 2001 VW TDI.

[@clintonkirker5154]

I have an x15. I run a bypass oil filter and still change my oil every 6 months or 50k-60k miles. Although I have run the oil longer. I use Amsoil oil. But a different bypass filter. I have an oil sample test with 80,000 miles, if you would be interested in seeing it, let me know. I’m currently at 544,000 miles. I have not yet needed the dpf cleaned, nor has the computer wanted me to do a parked regen.

[@freedomworx]

According to the internet, your engine should have blown up 400,000 miles ago. 😉

[@clintonkirker5154]

@@freedomworx yeah, when I first bought it, I was told I wouldn’t even get 150,000 miles out of it before it would be in the shop.

Cummins + Extended Oil Change = Instant Destruction (Allegedly) 😂

[@clintonkirker5154]

@@freedomworx I guess my Cummins is the exception. Oh and my engine specs are 450 hp @ 1800 rpms and 1850 @ 1200 rpms. Life time mpg is 8.08, So there is that also.

8.08??? You driving downhill 100% of the time? 😉

If anything, diesels need less cooling since they are more efficient..

[@freedomworx]

It’s a valid point.

Уважаемый Вы неправы. Очистить масло можно достаточно сильно и хорошо установив дополнительно к Полнопоточнику и Байпаснику Центрифужный масляный фильтр. Обратитесь в компанию Cummins Flitguard!

[@freedomworx]

You can filter it better with a centrifuge, but 99.9% (exact number) of diesels aren't filtered with a centrifuge. I'm not wrong, I'm simply explaining the reality of the vast majority of engines in use. If every engine was required to use a centrifuge filter, things would be different. But they aren't. Diesels hold more oil for the exact reasons that I stated. I could make the argument that you could easily drive an EV on a 5000 mile road trip....If there were enough charging stations along the way. But there are not. Thus, you cannot easily drive an EV on a 5000 mile roadtrip. Reality vs the Idealistic state🤷‍♂️

It’s funny you ask. I dreamed that I pooped in the bed last night. 😂

[@freedomworx]

Yes. But there was some info that couldn’t fit in the short, so I repurposed it.
