Has anyone tried running any other type of diesel fuel in the new cdi engines besides ultra low sulfur. Such as #2 or #1 diesel

lkchris

#2 diesel is ULSD

All you can use is #1/2 Duesel and B2/5 Biodiesel. Anything other than that will void the engine and fuel system warranty.

Don't even think of WVO or SVO, it won't work in them.

Just use what they were designed to use. It's stupid to buy a $50,000 vehicle and then pinch pennies on fuel.

240 DT:

I used cheap ATF (one liter per tank full of diesel) in my 1999 VW Jetta TDi. I used fully synthetic ATF (Mobil) in same and found zero ill effects. If anything it was quieter. The VW had a socketed chip which I replaced with an Upsolute one and there was no black smoke. Ontario rules for light diesel passenger cars is that you pass if the tail pipe blows no black smoke for longer than 15 seconds in any 30 second period.

Go to a testing station with a friendly myopic tester and you pass everytime.

The CDI and CRD engines can be destroyed by SVO and WVO. It won't burn correctly and the excess liquid fuel will pass the piston rings, enter the crankcase and dilute the engine oil.

I wasnt thinking about SVO or WVO. I am wondering if the older diesel fuel before Ultra Low sulfur such as low(not ultra low)sulfur and high sulfur will work in cdi engines.

I do not see why it would not. Diesel fuel is diesel fuel.

The dealership said it may destroy the converter and have possible engine damage, but i dont buy into that.

If the engine can run on ULSD then it should be able to run on Low sulfur and high sulfur diesel.

240D 3.0T

No, it will not be able to run on them.

In addition to the sulfur damaging the cats, it can damage the injectors.

240 DT:

I think the 2005 CDi can run on both low sulfur fuel (500 ppm) and ULSD (15 or 50 ppm) as the switch over to the latter did not happen in North America until the year 2007. Otherwise all 2005 common rail engines-converters will be toast.

I am unsure about my 2006 as Carlsson told me that the tuning box for the 2005 is available but the 2006 is still undergoing testing. Presumably there are differences in the engine management systems.

Saw a 1985 300 DT on eBay going for US$7,100. 156,000 miles and one owner. The car is in beautiful condition.

Is it worth considering such a high mileage example?

Define "high mileage".

The car is 22 years old, and traveled 7K miles per year since. That's pretty low, IMHO. All relative I guess.

Yes, it is worth considering....Only if you do all your own maintenance and/or have an independent capable of reliably servicing your ancient steed.

I have 3 diesels with ~300K miles on them each, from around that era. Since I know they've been taken care of (all service records), I wouldn't hesitate to take all three across the continent tomorrow. There is nothing to fail, really, on these cars that will get you stuck. Provided everything is mechanically sound, there should be no problems (and you take a couple of spare fuel filters).

It is now up to $7,600.00. Pricey for an old car!

DslBnz

True.

But being as old as it is,....Try finding one in the same condition. There are a lot less around now in great condition than there were 20 years ago.

I just looked at the listing. That car is gorgeous, black, and has a complete history record. Its going to be pricey. Cars like that don't some along every day.
