Diesel Escalade

Several years ago my DIL filled up my sons Dodge Cummins with gas and the results were NOT as good as the Caddies.
 
Sadly there will be many that will take that information and run with it, then wonder why they have problems after filling their diesel vehicles with gasoline.

If the story is to be believed, she was extremely lucky. Right combination of fuels and driving conditions.

aybe, Maybe not. In the second paragraph we learn that the author has a boyfriend.
 
It would depend on how much gas was added and how much diesel was in the tank already. I had a customer this summer put gas in a diesel tractor and got away with it. I caught it when he called me to fix a fuel leak (gas damaged the injector return boots on 4020). It ran good but the fuel was very thin and smelled like gas. I don't recommend doing this.

he author states that the vehicle was refilled after 350 miles and was averaging 25 miles per gallon. That would be about 14 gallons of gas, and the author states that the tank was down about 2/3, which implies that the tank holds around 21 gallons.

I wonder if this diesel powered Escalade has a common-rail fuel system? If so Ill bet this is fake information.

My neighbors Kubota tractor with common-rail fuel system didn't tolerate water/fungi in fuel requiring new diesel components to get engine operating again.

efinitely something not right. No diesel engine can go 250 miles on 2/3 gas, 1/3 diesel.

I did about the same thing with my JD 401B. Added 10 gal gas to probably 5 gal diesel already in the tank. I noticed it started running hotter than normal, and a little less power. I knew something wasn't right. After some checking I determined I added gas to my tank. After a filter change, and tank drain I was back in business. Wasn't very long after that I needed to have my pump rebuilt. Stan
 
In the 70s a coworker said when it got really cold and their VW Diesel jelled the owner's manual said to add 1 gallon of gas to 10 gallons of diesel.

So a little gas is ok.
 
Exactly ! I had a neighbour who ran trucks into Northern Ontario in the middle of winter and he always added 10% gasoline /diesel mix and he never had frozen diesel or frozen lines. I used to put a gallon of gas in my 584 Diesel tank when I filled.You can add a quart of oil to the mix to keep the pump lubed but is a good way to go in extreme cold

A quick google search reveals the author, one Brett Berk, is indeed a man. Who has a boyfriend.
 
The fuel pressure is 36,000 PSI - I know they filled with premium but that is beginning to sound like the fuel would combust within the fuel system - but I guess you need air.


The writer also spoke of delayed detonation - I would have thought you would get predetonation on the compression stroke.
 
I believe it is fake news. Putting as much gas as he says the did would really mess up the fuel system. On the 6.6 Duramax we had to clean everything from the fuel tank bottom to the injectors. The baby duramax is the same way. A gallon or so mixed in several years ago would not hurt but with the tolerances they have on the injectors and sensors now. I could be disastrous. About like putting DEF in the diesel tank,
 
JJMOR ...... I searched out the 'Jalopnik' website where this article showed up. The link below is from another website and it's opinion of what happens on Jalopnik. Mind you, the 'Definder' site might have as many crazies as Jalopnik. I too find it all hard to believe but who knows?

I would think that "John Barta, assistant chief engineer of GM"
Quoted in the article would demand his name and that attributed comments be removed from the article.
If not the entire article be retracted.

GM has hundreds of people and lawyers making sure media mentions of anything Gm is valid.

I seriously doubt GM would let this fake article live long.
 
We had a guy here in town that put def in the fuel tank of a brand new dodge cummins. It cost $10,000 to fix it and his insurance company paid for it.
 
When I worked in the JD dealership I tore down a skidder engine once where all the lands between the rings were broken. The head mechanic said possibly they had put some gas in the fuel tank to cause that.

Cadillac doesn't seem to list the fuel capacity for the Escalade on its web site, but other sources list it at around 28 gallons. That seems reasonable; a gasser Escalade wouldn't get far on 21 gallons. So the mix would have been around 50/50 gas to diesel.
 
For the folks who think the article is fake, I have to ask: What would motivate someone trying to make a living writing about cars to falsely claim to have made such a boneheaded mistake? Let alone to falsely quote a GM assistant chief engineer? (A quick search on LinkedIn gives John Barta's title as 'Assistant Chief Engineer Diesel Controls Systems at General Motors'.)

I suspect GM has already pulled this engine and sent it back to DMAX for teardown. Not only would they want to avoid any liability from selling a vehicle with a suspect engine, I imagine the DMAX engineers will be real interested to look inside it. I doubt running the engine on gasoline is one of their normal dyno runs.
 
Mark, gm couldn't care less about what they sell, as long as they get their money for it. My time in service at gm dealers has told me that. What do you think happens to the cars bought back under Lemon Laws? Do they crush them? Nope, they resell them through the used car program. You don't know how many times I ran a warranty check, and in the history was a buyback. Then you have the training center cars that have been apart 500 times to the point the wiring terminal are hogged out and threads are loose. Same thing, used car program.

This Escalade will be sent straight to the used program without so much as a courtesy wash. They don't care about R&D if it's still running.
 
The diesel rabbit I had would not crank if it was be!ow 32. Nothing worked but wait till it warmed a bit.

Geo, back in the 1960-70s up here in the winter in Canada the foresters that were using Diesel JD log skidders regularly added 1 gal of gas to 10 gal of Diesel fuel even though it was winter blend Diesel fuel already. But these JD engines were all old mechanical injection fuel systems, not modern electronically controller high pressure injection systems of todays engines.
These skidders were out in the woods all winter no where near electricity for a block heater. Some owners had even fitted couplers on the heater hoses of their PU trucks that they would connect to the ports on the block of the JD engine and run their truck to circulate the hot coolant through the engine block of the skidder before attempting to start it in the -30 t0 -40*F weather.
 
He say he borrowed it for a week, from GM or ??

A true automotive reviewer does not have to borrow a privately owned vehicle.

The manufacturer makes arrangements to provide the vehicle gratis.

He must be trying to become a reviewer, that article might do it.

It sounds like it was a GM fleet vehicle, based on statements in the article. And who (besides GM) would loan somebody their brand-new oil-burner without hammering into them the importance of using only diesel fuel?

Why? To get readers, of course!

It's working. Would a single one of us in this forum have read this article if it had not been brought to our attention? No. Why was it brought to our attention? Because of the far-fetched story it told! Would someone have thought to post this article on this forum if it had just been a boring review of the Escalade? No.

I've already seen it in three places. It was in my feed on Facebook. It was brought up on the RV website I belong to. It was brought up here. None of that would have happened unless it were some fanciful tale about running a diesel engine on 2/3 gasoline for 250+ miles.
 
Modern electronic fuel injection systems might handle mixed fuels better than the old mechanical diesel fuel injection systems. Some military vehicles are already setup to run on a wide range of fuels.
