Tip: When an engine is operating at normal temps and normal loads and the exhaust system is dry but the INTAKE IS WET WITH OIL... That's not wet stacking. That's oil in the intake mixing with EGR soot.

What does the EGR do? Introduce exhaust into the intake.
What temperature does the intake and EGR cooler peak at? Well below that where the fuel coke will burn off.

See also: why is intake coking reduced markedly when you get a remap that eliminates EGR flow when the engine is dead cold?
See also as well: Engine oil does not dry to a hard coke, neither does your typical hot exhaust soot.
Third see also: why does the EGR cooler plug up? It sees no engine oil.

So, it is free... you are only mixing it 5% so how much are you really gonna save?

I mean, there are so many reason NOT to use it (especially in a CR) and virtually no gain by doing it.

True. Adding a gallon per tank seems like more headache than it's worth. I'd be filling up cans to take home to my less finicky diesels.

Who do I ask at the airport about getting free fuel without getting stuffed into a black van and sent to cuba?

Pilots on some airplanes must sump fuel on a daily basis... usually it's on smaller planes, and creates 1-2 gallons of fuel a week on a turboprop. Back in my feeder pilot days in a caravan, I usually had a gallon jug that I would empty weekly at the company hanger. Usually there are barrels it gets dumped into, then burnt in heaters for the hanger. Sometimes there are much larger volumes, but that is usually put back into the plane after the required repairs.
Pilots and mechanics have been burning it for years, but when emissions engines came to the diesel cars/trucks, made it much higher risk.

I burn the Jet A in my salamander heater in the shop when it is cold, But I would never run it in my TDI, I thought some of my BMW motorcycle customers were cheap---but some of the people here take the cake. lol

...says the guy driving a 15 year old diesel

. I have a Saudi friend who couldn't understand why I'd buy a diesel car - apparently only ultra cheapskates buy them there.

Yeah, but when they run out of gas there.... They can always just get a full tank buying another new car.

I wouldn't run questionable fuel in a common rail, with a dpf. I, as well as people i know have ran strsight jet a, and had no adverse effects from it, but those were 7.3's, as well as ve pump engines.

I think it is more that gas is probably the equivalent of a quarter a gallon there

like in venezuela

You'd think, right? But the per capita income in Saudi Arabia is about one third that of the US. The rich are very rich, but most are not rich.

Used to be at Mojave apt they would hand it out free when the big jets arrived and had to be defueled before storage. Bunch of Yahoo's buggered that up getting caught with it in their 6.9 &7.3's. Which pissed off caltrans. Sometimes if you ask the refuel people you can buy it depending on their mood and weather.

I myself would either use power service white or find some winter D1 at a truck stop because they dont have weird stuff in them.
