Derogatory term for Detroit Diesel two-stroke Diesel engines, so named because they tend to consume lots of oil and leak oil. Some say that, on these engines, if you didn't have to add a gallon (or two, or three) of oil to the crankcase every time you stopped to get fuel, something was wrong.
Me: What engine do you have in your truck?
Truck driver: It's an old 12V92 Leaktroit. Thing drinks oil like breakfast but I still love it.

When an emissions device is "deleted", the device and any other relevant components in question are physically removed and the engine is then re-tuned to run without said device.
"Deleting" is different from "defeating" in the sense that "deleting" refers to physically removing emissions devices, but "defeating" involves disabling emissions devices while leaving all of them in place on the engine. For example, an EGR (exhaust gas recirculation) cooler can be defeated by welding it shut in some spot or blocking it off from one or both ends by inserting a metal plate between the cooler and the exhaust or intake manifold. DPF's (Diesel Particulate Filters) can be defeated by being drilled out or by installing bypass pipes.
On Diesel engines, people who do deletes will typically remove EGR (Exhaust Gas Recirculation) systems and DPF's (Diesel Particulate Filters), as these two systems are infamous for drastically increasing a Diesel engine's fuel consumption.

Here in Michigan we no longer have any kind of emissions testing, which means that today you can find quite a few deleted Diesel trucks, and even some cars and SUV's, running around in the state.

Get the deletemug. A word (or phrase) that has been overused or misused so much that it now has zero meaning whatsoever.
Over the years, countless words and phrases have become "zombie words" as they have lost their meaning from extreme overuse and misuse. Some of these words are "diversity", "simp", "racist", "toxic", "cringe", "abuse", "unprecedented", "Nazi", and "Fascist".

Get the zombie wordmug. Derogatory term for suburbia, so named because most of the main thoroughfares are "stroads" (wide fast roads with tons of entrances and exits).
Many of the people spreading FUD about "15-minute cities" grew up in suburban Stroadville and never knew what it is like to be in a truly walkable, pedestrian-friendly environment. Others, however, have managed to break out of that bubble and are actually advocating for better zoning.

The purpose of a DPF is to filter out particulate matter (a.k.a. black smoke) from a Diesel engine's exhaust, which consists of two distinct components, soot and ash. Soot is elemental carbon, which is the visible black stuff you see, and soot is the result of unburned fuel. Ash, on the other hand, consists of non-combustible metallic salts and is formed because engine oil contains many magnesium, calcium, and zinc compounds, and small amounts of oil are inevitably going to be burned along with the fuel.
A DPF is typically a big muffler with a ceramic honeycomb inside it that catches all this soot and ash and holds on to it. It doesn't let it out the tailpipe. It works well. But the problem is, it's a FILTER, and over time it's gonna get plugged. And once it's plugged up you now have an exhaust restriction, which is bad for your engine. It reduces your power, and you get all sorts of other problems. So how do you get the DPF to be clean again?
Many engines now have regeneration systems that spray fuel into the exhaust and blow air into it, then they light this fuel on fire so that the DPF can be heated to around 600°C in order for the soot be turned into carbon dioxide. This clears out the soot. Ash, on the other hand, is non-combustible and builds up in the DPF over time. Even during regeneration ash remains in the DPF and at some point you will have to wash the thing out or have it professionally cleaned in order to get rid of it.

From the year 2007 onwards basically all heavy-duty Diesel engines had to get a DPF in order to reduce particulate matter emissions, which lead to Diesel engine manufacturers ramping production up significantly in 2005 and 2006 so they could continue selling pre-DPF engines well into 2007.
