Thread: Anyone use fuel treatment / cleaner ?

It’s interesting to read all this i use cheapest diesel I can find which is typically United. Or Puma. I run cleaner through occasionally to try and get rid of algecides or water. But does premium diesel make a difference? Until someone shows me sdv6 or TDV8 on a dyno with real numbers it’s all BS. Seat of the pants is just misleading we want to believe we made a good choice. Nobody likes to know that maybe our impressions aren’t as good as we think. So no dyno numbers no zero to 100 kms numbers - then it’s bs

Same Meccles. 265,000km and fuel pump is fine, injectors are still injecting, etc. I’ve never used a single fuel treatment. I’ve bought diesel from everywhere and anywhere. Maybe I am lucky.

Rick130 who’s I’d is the most scientific on person on here has the best feedback which, via oil analysis, shows treatments risk doing more harm than good.

Fair 'nuff, and I totally expected this view, and accept folks belief of it.
I don't have a youtube channel trying to make a buck off it, with the consequent broad outreach Cardogan has.
I've never claimed to be an engineer, like it's some form of authoritative position, that I was somehow more believable than the next guy.

As for factual evidence .. next time I'm at the pump I may video the last 10lt fill for 'ya to visualise the foaming differences .. but either way it'll be meaningless.
Still not proof that the fuels are different other than they foam differently.

Does make commercial sense for Mobil to have two different products .. they're truck diesel is 2cpl cheaper than their car diesel, at this 7/11(near work .. on the Melb Ring Road just in case more factual evidence).
I'm also 99.99% sure at this station, they don't have a premium(and a normal) diesel product .. ie. 3 diesel fuels. They only show two prices on their board, truck diesel and diesel.

Like I said, I normally fill at Costco, but I sort of have to be up that way, otherwise a bit of a waste, so the 7/11 is my other option when I need a fill up.

I don't think it's the delivery system, but the way some diesels foam up in my D1 makes me believe that some are entirely different.
I'm thinking maybe remnants of winter diesel in the truck diesel at this Mobil .. same with the BP fuel we have at work.
Could be the pump, but unlikely.

Strangely tho, the car has some effect on foaming of the fuel too.
Many times out with bro in the Td5 DII, and we fill at the same pump(double handled pump) at a servo somewhere in the country, and where I struggle with the last 10lt his DII doesn't.
And just so we're clear here, I fill to the neck(and so does bro) and scoot off pretty much immediately, and always fill at a place where I also have a bit of a drive before I stop again.
eg. the Mobil is about 20klm from home, so I fill to the neck and then use about 2-3lt to get home so she don't overflow.

Would be interesting to see analysis of the different fuels.

Around home the diesel gets frothier around this time of year I think it’s the winter diesel being used

Spotted this while on a bike ride this morning...

Diesel standards are explained below. They are about limiting emissions, not about improving performance.
There was a difference between diesel for light vehicles (Euro 4) and diesel for heavy vehicles (Euro 5), but it seems all will have to meet Euro 5 soon.
There is a proposal to move to the Euro 6 standard.

I don't see any reference to 'premium diesel', so I don't know what that is.

Emission Standards: Australia: On-Road Vehicles and Engines

There's a detailed technical standard at the link below. I notice Australian diesel has a cetane rating of 46, but have read elsewhere that European diesel is rated 51.

Fuel Quality in Australia - Diesel fuel quality standard

There are some good links here:

Vehicle Emission Standards

I usually just buy the cheapest diesel available, mostly Puma. I have used a fuel treatment a few times, but I was mainly interested in making sure no bacteria bred in my tank. I have been told ethanol is used in some treatments, as a cleaner for the fuel system, but not sure how correct that is.

I use Fuel Doctor in my Disco 4 and Lucas fuel additive in wife's Subaru. Have read various Technical articles over the years about such additives and am in no doubt they do assist in prevention of wax, water, (condensation) and other nasty buildup in fuel systems and more particularly, fuel injectors, which can be VERY costly to replace! They also increase the Cetane rating slightly which gives some performance improvement. I am also convinced that the higher specced BP/Caltex (Vortex)/Shell diesel fuels have either higher Cetane rating or SOMETHING in their additive package which makes the engine appear to run better than with, say, United fuel. I have proven this to myself quite unintentionally a year ago. I sold my TDV8 RRS and (very stupidly) owned a new Isuzu mux prior to selling it last October to buy a MY13 disco 4.
Whilst owing the mux I got ARB to fit a long range fuel tank as the original is a pathetic 65 litres. ARB told me i had to deliver it with bugger all fuel in the tank to make it easier for them, and also that they'd fill the new LR tank with fuel to ensure no leaks etc. Fine.
I'd always used United here in Hobart as being a RACT member United give 6cpl discount to members.
Upon collecting the mux from ARB with full tank I immediately within 5 klms detected the car seemed more perky off the traffic lights and after the 40 odd klm trip home I felt it was running sweeter.
Long story short, I rang them and found they'd filled it with BP diesel from the servo down the road from their shop.
Now, read into that whatever you will, and call me a silly old bugger and anything else you like, but I was ( in another work life many years ago), a diesel mechanic and motor mechanic. Had a workshop employing 4 mechs and specialising in Jaguar, R-Rover, Bentley and all English cars, so I am quite conversant with cars, engines, and whatever. I am convinced that whilst United may sell their fuel with correct (legal Govt) Cetane rating, some of the other fuels are definitely superior in performance they deliver.
