VW fuel additive

[Transporter]

You will always need some additive, because the underground storage tanks aren't always clean. There is a fuel return line in our vehicles and returned fuel is heated up and will cause the water condensation in the fuel system and settling in the fuel tank. For the petrol engines I recommend and use Interject 415R and BG 44K. I get the best feedback from BG 244J diesel additive, but be ready to pay double for it compared to VW diesel additive.

Maybe VW should also look onto the ridiculous long service intervals for the fuel filters. There is an option to change the fuel filter more often for the countries that don't meet the EU fuel standard, but in AU they fobbed it of saying that the fuel here meets the EU standard, but the reality could be different. Then the car owners are left to fight the fuel suppliers, because the warranty doesn't cover the contaminated fuel, and the fuel company are saying that our fuel is perfect.

It's so perfect that many carmakers until the recent time didn't bring their modern (CR) diesels into AU. Except, MB, VW and Peugeot.

Well, on paper (as in, enshrined in regulatory law), Australian diesel is more or less uniform with EN590.

It's just a hunch of mine, but I can't imagine the fuel coming out of our refineries would be of a lesser standard (though nothing is impossible).

Assuming we take that for granted, one would then have to look at what happens to the fuel during the period between when it is drawn from the refinery terminal and when it eventually ends up in the vehicle's fuel tank.

I'd assume there are strict procedures regarding handling, storage, transportation, maintenance and all the rest of it, so I suppose it then becomes a matter of how closely they're followed, if at all.

BP and Shell offer a fuel guarantee for most fuel purchases (see their website for terms and conditions). I don't know if recent changes to Australian consumer law make those fuel guarantees sort of redundant (especially in regards to other fuel companies), but BP and Shell at least make their guarantees visible for everyone to see and read.

Used the VW additive a few times.....haven't noticed any difference to performance or fuel economy. So, not sure what it is good for.

Speaking of additives, I recently tried a can of Liqui Moly Diesel Particulate Filter Anti-Clog.
On the initial tank of fuel it was mixed with, I didn't really notice much difference. The following 3 tanks, I have been getting 1000km out of a tank. I usually get 850km out of the tank.
Pretty happy with the results so far.

I used original VW additive now sold at official dealers. (pertol version of it). Did not see any identifiable difference, but maybe this is less about improvement of healthy engines, but more about prevention: keeping the carbon build-up down, to make sure things do not get worse later on.
