I have heard that at temps of -15C and lower, the diesel starts 'waxing' in the tank which means the car may not start or if it does may not run properly.

As unlikely as it may be to get that cold (although it did quite often in 2010 winter), I have a couple of questions:

1: Would Shell V-Power diesel or BP Ultimate diesel be more resistant to waxing?

2: Can you purchase a diesel additive that will resist waxing?

Have you looked at Archoil AR6200?

It seems to cover most things, including adding additional lubrication.

I have just ordered some, so will be using it soon.

Had problem with diesel waxing in my Freelander 2 last winter. Filled it up with BP diesel drove to France, left it overnight in hotel car park where temperature went down to -16C. Next morning car started and ran normally for about 5 miles until I went to accelerate onto the Autoroute at which point it went into Reduced Engine Performance limp mode.

I cleared the limp mode, drove slowly to the next service area, filled up with French diesel and car returned to normal running, albeit with Reduced Engine Performance warning on message centre. Message centre cleared when i left it switched off for over 30 minutes while stopped for lunch and everything has been fine since.

You could just add 10% petrol to your diesel when you fill-up, alternatively use this,

they put petrol in here at the pumps during the winter months, never had a problem.

Won't the petrol effect the lubrication of the fuel pump and injectors?

yeah it will : (

I believe petrol is added here in the UK too, so I'd be very careful about adding more!

As for the petrol affecting the lubrication, I wonder how long before someone suggests adding 2-stroke. Oh, damn, I just did...

Any thoughts on the 'super diesel' having any benefits in this regard? LL.B (Hons) - University of Derby

I'm afraid not, nothing electrical, the fuel filter has a 'pre-heat' function but this is a thermostat that recirculates the fuel through the canister instead of returning it to the tank. It then gets it heat by being next to the engine and being constantly on the move.

From the middle of November the UK fuel stations will be on Winter Diesel that will have additives to help combat this, although -15 is quoted it seems this can be exceeded by quite an amount.

By the way, our engines are modern direct injection and adding petrol will allow the high compression to detonate the petrol early, not recommended unless you have pre 2000 diesels.

guys guys guys calm down i'm sure youre over thinking all this When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car

Yes, my previous TD4e was faultless in the winter of 2010 and I used BP standard diesel.

I don't think anyone is worried, it just makes a talking point.

Not sure about the original question (BP Ultimate/ Shell VPower).

However, if the temperature drops to say -15 the likelyhood of the fuel dropping to that temperature also is remote, it would have to be even colder before it caused problems, before we even factor into using winter diesel. Mine: 2012 Golf GTI Edition 35
