When travelling along at 100K there is a loss of power. Feels like the turbo is deactivated. No engine light was activated at any stage.

If I lift foot off accelerator for a second and reaccelerated all was ok.

Happened at regular intervals.

Never happened when acceding or descending larger hills

Interesting facts.

Only happened after filling at Tenterfield on the way to Glen Innes. Happen all week driving Inverell – Glen area.

Also added diesel at Glenn as it has a higher mountain fuel rating than Tenterfield. This was to prevent fuel freezing.

On the way back to Brisbane filled at Warwick and never experienced the problem again.

Things to note when it happened.

1. High humidity. It had been raining all week.
2. High altitude compared with Brisbane.
3. Low temperatures usually lower than 15 C.
4. Had mountain diesel.

Problem not evident now.

I use Alpine diesel all through winter and don't experience any loss in power. Can't answer why you're 3.0l looses pwr.

I dont suppose its a good idea to post the actual service station/s used but if they were reputable sites I couldnt see a prob with the fuel.
However as im in the fuel industry there are operators out there that add more heating oil to the winter mix than is recommended I know that in the southern highlands the company I work for delivers a 50/50 blend of deisel/heating oil( alpine deisel )with no apparent problems. This could cause a very small power loss due to the difference in flash point from regualar low sulpher deisel, But with these electronic engine control sensors it could two fold the power loss. Some so called bodgey operators will try to get away with some low acts just to save a dollar.
Do yourself a favour as Im sure you do and keep with one fuel company if possible, not only for peice of mind but if the worst happens(fuel pump etc) than at least you have proof of purchase to assist in a fight.

Good Day Redeye,
I have a 2002 3ltr, faced a similar problem at first minor problems then steadily progressed over time. The problem turned out to be a faulty EGR valve, currently being replaced, suffered loss of power, heavy fuel use etc, how many kms on your unit?
Local nissan dealer has had three units ranging from 80 to 100 kms all experiencing same problem all having EGR valves replaced.
Might be worth a look?
Regards

What sort of heavy fuel consumption figures do you get?

Leroy,
Drppoed by about 10 to 15 % then almost 50% of normal.
In earlier post should have said 80000 to 100000 kms when fault starts to appear, Nissanm are currently apparently starting a log of these incidents to see if perhaps a recall is required.

Recall? LMAO! if they werent doing a recall for engines blowing up left right and center, 5th gears, etc it would probably have to be every single unit sold for them to consider a recall...

Yeah our work car had air flow sensors and EGR's go, the EGR still isn't 100%. Power loss and then ECU light. It was with them for weeks, they fixed the ECU light comming on and the power loss is no where near as bad as it was but it is still there from time to time. (I reckon they just unplugged the ECU light!! LMAO).

I wasn't aware that Alpine Diesel existed.

I was living and still work in the Gold Coast hinterland near Mt Tamborine which in some areas is 200 - 300 metres above sea level and get down to minus 4. Is there a substantial effect on performance at higher altitudes?

Hello Wizard,
Diesel contains a percentage of wax. If cold enough this wax comes out of solution into "lumps".
Winter or Alpine mix foms these "lumps" at a lower temperature than Summer mix. From what I can remember of how it was explained to me, it'd need to be consistently colder than -4 to trouble you.

For what it's worth, Diesel has a Cetane rating where Petrol has an Octane rating.
