Unleaded petrol mixed with Diesel in a Chrysler 2.5CRD

They have sold CR and Unit Injector engines for donkeys years but not with
the high injection pressures now utilised and not until about seven or eight
years ago commonly with solenoid injectors with multiple phases per cycle.
John Deere are having terrible trouble with their recently introduced CR
engines allegedly. They blame UK fuel but I am willing to put some money on
it [if indeed there is a problem] being universal and international.
Further, these engines are industrial engines built to be robust heavy duty
units not light duty car engines.

Having said all that, I would agree that these small engines should be and
generally are robust and reliable. At present though, some engines do have
fuel system problems. A well established example is the Isuzu 3.0 unit
oil-over-fuel injected engine which has Cat type unit pump-injectors. These
have had a very high incidence of catastrophic failure mainly due to
injector sleaves leaking fuel into the oil and filling the crankcase with
diesel until the engine literally explodes. Nissan CR engines have a high
failure rate of CR systems with metal particles contaminateing the system
due to component failure. I could go on about injectors, variable nozzle
turbo's, excessive EGR and the damage caused etc etc..

In the UK diesel is also more expensive than petrol but that does not stop
almost 50% of cars being sold with diesel engines.

Cat have started producing CR engines out of their Peterborough England
factory. I have no idea who has actually taken the engine so far because we
are about a year from having to use it through legistlation. Above 200hp the
tier three offroad is already more strict and high pressure systems
combined with four valves are now commonplace. Perhaps the Cat/Perkins 4.4
and 6.0 CR engines are used in some trucks already but I have no information
regarding this yet.

I would like to think you were right but I see no evidence of a gas light
having tollerance for 20% electricity.

This is fairly common even today at modern supermarket stations. It is
amazing that this can happen in modern service stations but it does.

But people aren't free to pump their own gas.

 

Damn. Hail, snow and ice have blocked off the M4...

Whatever the OP's car (not a PT Cruiser) I am a bit surprised this
wholelsale condemnation of the PT ccruiser hasn't attracted a mass of
flaming from enthusiastic PT Cruiser owners participating in the Chrysler
NG.

Or maybe there aren't any and everyone is in agreement...?

What's the relevance of that? In my neck of the woods (London) diesel has
cost the same as or been dearer than standard 95-octane petrol for a year or
more. Fuel 'duty' (tax) is the same on both now.

What's your opinion of Mercedes and Peugeot diesel engines?

This was Oklahoma.

However; I'm British and used to buying bangers. You think I would buy a
dangerous car? There wasn't a trace of rust on that old Eldorado's
underbody/brake/fuel lines, only a scratch on the front wing and the
split seats let it down.

The Eldorado was from a Chevy dealer, too. The car I had before was a
1979 Regal 2dr bought on eBay for $400 (I liked the Eldorado better, but
I did do some running servicing on the Buick like replacing the PCV and
ignition systems. Yeay Autozone, or something. So cheap!).

What a pity. It was raining heavily when I got home from headbanging at 2am
this morning.

Welcome to the world of petrol attendants. They exist in other countries,
too, even in Europe. Some also take you payment on the forecourt, so at
least you get a bit more service.

Bill, I am sure you are enjoying this conversation mainly among Brits (a
rate treat in the Chrysler NG) but clearly you don't yet have a full grip on
the terminology... you can also fill a petrol tank with diesel... (without
harming the car)... (Also note the lack of swearing but occasional
fine insult....)

Well, enjoy the concert, which will no doubt be Bringing Back Memories of
Your Youth..

And last night WE went to an interview of Malcolm Rifkind (he suppports
David Cameron, BTW, and is my MP) by an senior Times editor, followed by
dinner in a local Greek establishment...not quite headbanging but a nice
treat during the week.

DAS

PS. For the non-Brits: Sir Malcolm Rifkind is a former Foreign and Defence
Secretary, MP, and (until very recently) on the front bench of the
Conservative opposition. Today the Conservative Party will announce its new
leader and later in the week we should know whether MR will again be in the
shadow government.

Great while they go. I've a Vito CDi with a wrecked engine at the moment.
Only 45000 miles. We thought at first that it had a fuel injector problem
because it was slow starting and smoked a bit. It turns out that it has bent
conrods among other extensive damage and effectively it needs a new engine.
All these new diesels are *extremely* expensive to repair. They are also
very complex compared to most petrol engines.
When they do work, they work extremely well. The little Peugeot 1.4 engine
exceeds the performance of most 1.6 petrol engines of less than a decade ago
but its installation in cheap cars means that a fairly small repair, like
injector replacement, when several years old is likely to be uneconomic. I
haven't priced an injector but some can be as high as £400 *each*

That takes a real effort of stupidity though, the filler necks smaller

 

Maybe you always call it a diesel tank, but I (and many others) don't.

I thought that that was actually the case; but that the Diesel filler
used a larger nozzle than gasoline, therefore it would prevent people
from putting Diesel in a gasoline car but not vice versa. Remember
back to when unleaded gasoline was introduced; the filler neck of
vehicles with a cat had "restrictors" in them so that only the new,
smaller unleaded nozzle would fit. I assume that that is still the
case to this day but it has been so long since I've seen a leaded gas
pump that I couldn't say for sure. It's also possible that the new,
smaller nozzles are so universal that they're being used for
everything, not just unleaded gasoline, but I haven't driven a Diesel
vehicle in a while either.

I do remember my grandfather buying a new Chevy pickup right when this
changeover was occurring; I think it was a '76 model. It ended up with
a standard carburetor and exhaust system (no cat) but had the new fuel
filler with the restrictor and "unleaded fuel only" stickers. Not sure
if he just knocked the restrictor out with a chisel or bought a new
filler; this was quite a few years ago.

Completely off topic; I recall that the truck he was replacing was a
'73 that my dad ended up buying. He lost the gas cap at some point
maybe 20 years later; it was a PITA to find a new gas cap, it turned
out that it had a '72 model filler neck on it. Not sure how that
worked; as a '72 would have had the gas tank filler in the cab but the
'73 was on the pass. side rear fender, but there you have it. I also
remember at some point the fender was replaced with a junkyard
replacement, and apparently 74-up fenders relocated the gas filler up
higher and it was much easier to refuel from that point on (didn't have
to leave the pump set on the lowest flow setting to keep it from
kicking off early.) Gotta love GM...

I had a vehicle come in that had been to a store where a person stole
diesel and drove off with the pump handle
still in the vehicle,the store put another nozzle on the pump wich was
for an unleaded pump,85 vehicles got
deisel fuel that day before anyone noticed.

Yeah - us yanks have a sloppy habit of sometimes calling any fuel tank
(diesel, gasoline, or other) a gas tank, when in most other contexts
having to do with vehicles, the term "gas" is short for "gasoline"
(petrol) and would not be used when speciifally referring to diesel
(although that happens occassionally too) - just habit in a
gasoline-centric culture.

It is refreshing to read the Brit conversations - I think I needed a
translator for some of the posts. Yous guys have made a mess of the
English language.
