Interesting about the cetane booster in the diesel, I have a wee bottle of it at home to try in the wife's Evoque.
Probably the Worlds greatest Polo resource

The A4 is marginally more responsive with it and the mpg difference is very noticeable. I really noticed not putting it in prior to my 105 mile round trip on Monday.Andy Beats wrote: ↑Wed Oct 28, 2020 10:56 am Interesting about the cetane booster in the diesel, I have a wee bottle of it at home to try in the wife's Evoque.
It's more for keeping the DPF as clean as possible, TBH.monkeyhanger wrote: ↑Wed Oct 28, 2020 12:19 pmThe A4 is marginally more responsive with it and the mpg difference is very noticeable.

Millers Ecomax is what I use. The can is about 4 years old and half used - we stopped using it when I chopped the wife's A1 1.6TDI in for my 2018 Polo GTI+ and we still had the Golf R. It stinks though!
I'm pretty sceptical about snakeoil products and wet panel filters etc., but Cetane boosting benefits are well established. Mine is Euro6 with Ad-blue, with the DPF pretty much stuck to the first bit of the exhaust manifold to heat up ASAP.Andy Beats wrote: ↑Wed Oct 28, 2020 2:57 pmIt's more for keeping the DPF as clean as possible, TBH.monkeyhanger wrote: ↑Wed Oct 28, 2020 12:19 pmThe A4 is marginally more responsive with it and the mpg difference is very noticeable.

It's a Euro 6 car, so the DPF is really close to the engine (like, REALLY close..) and should run higher temps than older DPF cars
Still, I don't kind a few extra quid to chuck in some snake oil.
Adblue is post DPF though, isn't it?monkeyhanger wrote: ↑Wed Oct 28, 2020 4:21 pm Mine is Euro6 with Ad-blue, with the DPF pretty much stuck to the first bit of the exhaust manifold to heat up ASAP.
Yep, Adblue is post DPF, as is all the active exhaust system. Just differentiating because early EU6 cars (like my 2013 Golf GTD) didn't have adblue and newer variants (from about 2017) do.Andy Beats wrote: ↑Wed Oct 28, 2020 4:43 pmAdblue is post DPF though, isn't it?monkeyhanger wrote: ↑Wed Oct 28, 2020 4:21 pm Mine is Euro6 with Ad-blue, with the DPF pretty much stuck to the first bit of the exhaust manifold to heat up ASAP.
So how do Audi (and LR) raise temps for regens?
Renault inject more diesel, my Mini had EOLYS fluid that raised temps.
Maybe they figure the repositioned DPF raises temps enough, dunno.
