For what? 99% of cars on UK roads wont benefit from it anyway. But if you are fortunate to own such a vehicle, Shell V power is better because it is 99 RON, BP ultimate is only 97 RON

I just want to use it once every 4 tanks, once in a quarter to help main my Diesel engine...?
Mine is diesel so higher the Cetane Number CN the better? But where can I find this information from?

Both premium diesel from each supplier
If you’re wanting a fuel to help clean the injectors / carbon build up rather than for power I would go for Esso Supreme , but doing it 4 times a year won’t really make much difference. Like all additives their “results” are based on constant use

Mainly the DPF filter?
DPF regens when it gets really hot, so a good ragging down the motorway once a month (keeping to the National speed limit of course) usually keeps that well clear
My Octavia has just cleared 136,000 miles doing just this and its on its original turbo
You asked: Shell V Power OR BP Ultimate Diesel?

Is there any difference? forums.overclockers.co.uk/thr…30/

I buy the cheapest diesel for a diesel turbo with DPF for exhaust.
I heard a guy answer this question.. He said spend the money saved by using standard fuel on your partner, as your own motor will be sure of a good run. I'm not going to argue

Does your dashbaord have a DFP warning light?!

Second supplement advice, drive faster (out of town) and on dual carrriage, above 40mph for around 10 to 15 minutes. So, if you do frequent 50 mph+ , then youu are wasting money 5p/litre.

vwgenuineparts.co.uk/DPF…tml
"You should drive your vehicle for approximately 15 minutes keeping the engine revs between 2000 - 2500 rpm. This is probably best done on an A road. Keep the car in a lower than normal gear (use 'S' (sport) on an automatic, if there) in order to keep the revs up."

Or, you just park somewhere in open air, and put your foot on to keep revving at 2000-2500 rpm for 15-20 mins.

And, if one has that dreaded "Adblue" warning light which says your car stops ater so many hundred miles, which comes on even when Adblue is working, one can also park and trigger using a VCDS tool to connect to the Engine Management System, to start the System Catalytic Reduction (SCR) process, takes my engine 20 mins, and this process also reset the "Adblue" mileage limit counter. In this SCR process, the ECM (Engine Control Management) maintains the revving for you at constant 1500 rpm.

Surely the point of owning a diesel is to save on fuel costs, I have a Octavia 1.6 diesel with Dpf, I don't give it any special treatment, just drive it as normal and let the Dpf take care of itself, if I get home half way through a regen I still park up knowing it will do another regen in the next few journeys. I am on 68.000 now and no problems from dpf.

I have never had to do a DPF clean, driving around using the certain RPM for enough minutes will do it. I don't know why some people still get issues when revving the engine around.

It wouldn't be the diesel, as Euro engine specification means any diesel fuel is usable by any diesel car from Russia to Morrocco and beyond. The key is the engine oil specification, never the fuel except for performance.

I always use a high grade oil. How often do you change oil?

You can tell on mine as when you are at red lights for example the engine idles at 1100rpm instead of 800rpm. Also if you finish your journey before the regen has completed the engine fan will come on for a few mins to cool down the Dpf filter.

You're lucky, That is 100% going to cause problems like the oil level rising as the unburned diesel ends up in the sump etc.. Potentially blowing the engine and it will 100% shorten the life of the DPF.

It's your choice but it is bad advice.

At least change your oil frequently, That should help reduce the threat of the oil level rising and blowing your engine.

I hear the fan now and again when I’m parked (very loud) but ain’t sure if that’s cooling the engine or not... hmmm

I have been using it, It's basically as pure a cetane booster/enhancer as you'll get in it's chemical form etc.., Some folk add some 2-stroke oil to aid lubrication too but that's not really necessary. It supposedly makes negligible difference and can't say that I've noticed any difference. A certain placebo effect maybe but certainly better than the likes of redex etc which contains about 99% bulking agent . I used the logic that it'll help raise the cetane level to that of premium diesel but at a far lower cost.

Check your temp gauge, It's most probably doing a regen if the fan is spinning, Listen to the exhaust/engine note and the revs will likely be higher than usual. Also you may smell an acrid smell from the exhaust etc.. If you've got a live active fuel consumption on your trip computer you'll likely see the mpg reduce dramatically etc.. if you've got stop/start it won't be active during regen.

When mine is doing a regen I try and find a fast road, Stick it in 3rd and accelerate to between 3-4k. If I can't get to a fast road 2nd and accelerate to 3-4k etc.. 110k on my car and 0 DPF problems.

Yes, logic of higher Cetane level the better is a fact. I fuelled up Shell vPower diesel yesterday n it was 10p extra per litre - bloody ridiculous!

So is the Hydra2 100% reliable n proven to work, fairly cheap for its size?

Yes, I also read that in a few places on 2 Stroke oil to help with lubrication...?

Yes, I will monitor MPG on trip computer n also the Stop/Start. What about engine oil, does it need to heat up to a certain level before regen?

There are other brands of "2 EHN 99% 2 Ethylhexyl Nitrate" just make sure they're "99%". Most additives are snake oil or contain little that actually do anything. It works out about £1 a tank. I haven't done any comparisons but I know that premium diesel in general makes zero economical sense. That extra 10p per litre could go towards an extra litre or two of regular diesel which is perfectly fine for your car.

I understand how the cetane level can lower the combustion temp which has many benefits etc..

The car supposedly has to reach a certain temp before a regen is activated, Mine seems to be happy to activate around 60c before it's reached usual operating temp etc.. so will likely vary across manufacturers.

Just make sure you change oil frequently, Don't be fooled by premium oil either. So long as it meets or surpasses the manufactures standards in your hand book then it'll be perfectly fine etc.. This guy did a comparison for example. Amazon basics oil actually won most tests etc..
So did you buy Hydra2 upon recommendation? I’m going to buy one of these type additives...

You never considered 2 stroke oil?

As specified, VW 507.00 (must for DFP), I but the Shell Helix Ultra ECT 5W-30 (fully synth) which is ACEA C3 , ain't cheap at around £40 per 5L; specs says 10,000 miles or 12 months (whichever occurs first) <-- I tend to follow mileage faithfully and depends on short versus long drives, if lots of long drives then 12000 miles is OK; rather than time (of say 18 month, two years)


The key is the low saps for DPF filters, all good for use C1 to C3 (C3 is still good, it is a bit of qualitative thinking between C1 to C3 difference in actual usage as so many other factors come into play) :-

From the AA:- (however Shell's specification on Shell Helix Ultra ECT 5W-30 states it is a low SAPS even though at ACEA C3)


ACEA C1 Low SAPS (0.5% ash) fuel efficient
C2 Mid SAPS (0.8% ash) fuel efficient, performance
C3 Mid SAPS (0.8% ash)

==================================================

Edit: 1 August This is also good at half the price £20 (5 Litres), compared to Shell Helix Ultra ECT 5W-30 ACEA C3 (£40)

Shell Helix HX8 ECT (ACEA C3) uses advanced emissions-compatible technology that helps to keep diesel particulate filters clean to help maintain engine performance. (according to Shell's specs shell-livedocs.com/dat…pdf

If you are trying to pro long the life of the dpf -use high grade low ash fully sinthetic engine oil and change your oil once a year or every 20,000 .

Hi, that will more than likely be to cool the Dpf after a regen, and not the engine, the only time the fan needs to cut in to cool the engine is if you have been stuck in traffic for several minutes, due to no air flow through the radiator to cool down the coolant water. Mine does several regenerations every thousand miles so regularly hear the fan if I have ended a journey halfway through a regen, don't worry about it as it will complete the regen on the next journey.

Yes and upon research, Don't knowingly disrupt the regeneration if you can help it. Not all cars will continue and rising the oil level is a known problem. It dilutes the oil which can blow the engine and potentially damage seals and gaskets etc. Amongst many other potential problems etc.. The fans run during the regeneration and a little after. Whilst the Dpf needs to get extremely hot the engine doesn't hence why the fans run.

I figured that since the additive is only 100ml a time then the lubricating properties won't have been diminished that much. You can let me know if it is of any benefit for you though if you want to try it
The fan is for the dpf, my golf runs the fan when I park up from time to time.

I’ve ran the top diesel from shell, Esso and bp in my Jeep Grand Cherokee for a 5k mile period and didn’t really notice any benefit. I’ve gone back to buying from the local supermarket.

If the loud fan when just parked is for the DPF then I’m happy 😃

I’ve put millers in but I can never remember to put it in on each tank.

I have a heavy foot at times so happy enough it gets a good dusting.
