Re: SAVE ON FUEL ?
‘Before we start, All HDi, CDi, TDCi TCDi etc etc. and nearly ALL POST 1999 YEAR COMMON-RAIL and UNIT INJECTOR type Vehicles WILL NOT RUN ON VEGETABLE OIL (SVO, WVO, PPO etc.)–Try and YOU WILL KILL IT’
So, in other words virtually no modern diesel engine under 12 years old is safe to run on this stuff. 😉

Without conversion :wink:. That’s why you need to fit a heat exchanger, like the photos and manual I posted, rather than just chuck some veg oil in the tank.Re: SAVE ON FUEL ?
I have run my LDV Pilot on neat veg oil, when it was cheaper, in the summer (never in the winter) for some time and it actually goes better on it but the engine is an old pre 2000 design Peugeot 1900 so was ok. Not sure about the new VW though.
At first I thought there were lots of barbeques around until I twigged it was me.Re: SAVE ON FUEL ?

Looking at those photo’s and seeing all the plumbing needed, I can’t imagine there’s any room under the bonnet of my van to fit it all in!
Not enough room to stick a battered cod on the engine block never mind the oil to cook it in!
And where would I stick the auxiliary fuel tank?….on second thoughts, don’t answer that. 😈

That was the only downside :wink:. Have built a load of racking over the fuel tank though, to make up for it a bit.
I think your Astra has the same engine? It’s a squeeze to get it all in but in the end most of the plumbing runs along existing fuel and coolant lines, only new part is the heat exchanger which I just ran where I could along the edge of the engine bay. Certainly not enough room to squeeze a cat, though!

Nah, sadly not so Chris, in my case there’s a huge great turbocharger behind the engine block and a chuffin’ load of pumps, pulleys and pipes for the AC unit between the engine and rad. Seriously, there ain’t no room for all that plumbing and insulated pipework. Gord knows where the ‘heat exchanger’ would fit?
Besides, when it comes to general annual servicing and the local garage mechanic lifts the bonnet and finds all that lot in there, what’s the chance they ain’t gonna bother servicing it, or at best just just change the oil and air and pollen filters at best?
But then when I ‘reckon it all up’……”there’s always a catch!”
Re: SAVE ON FUEL ?
Not much room in my vehicle and reading this from the article above is another reason I won’t be ‘converted’
‘Also worth remembering,- Any SVO or Vegetable-Oil Conversion Will Invalidate a Vehicle maker’s Warrantee, especially if after fitting, a fault should develop with the engine or fuel-system….
A stuffed up fuel-system caused by the incorrect conversion or mis-use of vegetable oil on a Post 1999 vehicle can literally cost thousands to sort out’

Not trying to “convert” anyone, just put the option out there as, let’s face it, with diesel at £1.40+ per litre can take a huge bite out of margins on jobs, especially those of us in rural areas who do a lot of mileage, and “free” fuel is a great cost saver.
But obviously if you drive a new van under warranty then you’d be mad to do this – if a dealer catches a glimpse of it they’d be rubbing their hands with glee for sure.
As for that engine bay… plastic fanastic! Looks more like a warp drive than an engine – very posh :wink:.

TBH I rarely ever put regular diesel in my car, I use the premium grade 9 times out of 10. The cost of a knackered DPF is something I want to avoid. 😉

Re: SAVE ON FUEL ?
Does it really make that much difference and better MPG Jim?
I want my new van to have the best treatment and maybe last until I peg it…………….in 2060.
RobRe: SAVE ON FUEL ?
Flippin’ eck! I didn’t realise that diesel comes in different grades? Mind you, I do pay special attention in picking out the black filling nozzle instead of the green one but didn’t know there were different shades of black? 😕
Re: SAVE ON FUEL ?
Yes, two generally.
Pay attention Martin. 😉
There’s “regular” for the commoners and “premium” for the people with a few pence more a litre to spend. That few pence however for higher performance diesels is probably worth the trouble, the older or less complex diesels it’s probably not IMO.
I don’t know that it makes a heap of difference in the end TBH but I do think the better stuff gets a bit more MPG and, as Jim says, it likely clears the DPF a bit better if you have one, which is mandatory I think on newer vehicles.
A messed up DPF is not pretty, trust me, I know this from first hand experience. :rolls:

Re: SAVE ON FUEL ?
Words of wisdom from a recognised expert. Honest John
The extra mileage is minimal unless you are going on a long trip.
However, the DPF auto cleaning system has never, ever kicked in on my 20 month old car and it does a lot of short trips as well as longer ones. that tells me that the fuel I am using is helping to keep the DPF clean. 8)
BP Ultimate and Total Excellium are the two I use round here but both Shell and Texaco also have their own premium brands.

Re: SAVE ON FUEL ?
Just read the manual on my VW.
Don’t use biofuel on any van fitted with a DPF
No more trips to Makro for the old cooking oil.

DPFs are a bit of a con though – I know plenty of people driving round on normal diesel who have problems with them. Personally I think any engine needs a good hard run at high revs every once in a while, of which I’m happy to oblige :).
