A Diesel E30?.

[Zayyan]

The sealant/tyre inflator is a good idea

If the average puncture interval is really 96,000 miles I'm taking my spare out to improve fuel economy!

[Widge]

I'd have made more use of carrying a spare cylinder head than a spare wheel.

Brian how does LPG work?
Ok slightly less vague question, how does it change the amount of lpg depending on the throttle position engine speed etc.. Because all the LPG mixerplates I have seen are just a jet in a bit of aluminium to go before the butterfly.

[Brianmoooore]

Theres a electricaly controlled valve, similar in construction to a idle control valve in the gas vapour line just before it enters the mixer plate

i like diesels with more than 4 cylinders, my dad has a 4.2 24v landcruiser and that sounds quite nice-ish...

but then i heard someone absolutely rag one of those new VW Tourag V10 diesels the otherday, right past me as i was walking, oh the noise!

so basically as far as i'm concerned diesels are now officially cool just have to have enough cylinders

[Richy325iTouring]

Oooooh yeah! I've done the hard ones now. Just marketing this wednesday left. So I'm chilling.

I'd love my touring with a 330d engine. That would rule. 40mpg, and fast as fcuk!

ever driven an e46 330d

sweet car dont even sound like a diesel and the performance puts a lot ofpetrol car with simular power to shame

i so want that engine

[Andy_magic]

Those VW Toureg diesels can be tuned to give more power (and much better MPG) than a Porche Cayenne (The most powerfull one)

There are 2 types of diesel engine commonly used in cars and trucks, Indirect injection and direct, the direct injection are more thermally efficient than indirects but make a lot more combustion noise when idling or on light loadings.

If anyone is doubting the power output of a modern diesel, try racing a pikey in an audi A4 diesel

The only downside to a diesel is that they need servicing more often, but these services are usually cheaper than a petrol engine service as there is less to change.

If anyone does actually stick a 325/330d motor in an E30 I would love to have a go, the power to weight ratio would be great and a ton of fun to drive IMHO

[SCOTT325SE]

BMW themselves did some research a few years ago, and came up with an average puncture interval (IIRC), of 96,000 miles.

Does that include valve failures? If so, i arent due another spare wheel change in 288,000 miles!!!! Sounds bloody good to me!

[psychochild187]

vw have started using some very special deisel oil that needs a sertant standard like vvot 501 or some odd code like that
i costs about 28 quid for 5 ltr .

if you dont use that oil and go for a slightly different one

BANG!

[Toby_Unna]

what's so different about the vw engine to other powerful diesels?
sounds like vw trying to make more money!

[Andy_magic]

Nothing as far as i know, It's going to be a fully synthetic oil. Mobil 1 is about Ԛ£30 for 5 litres.

If you can afford Ԛ£40k+ for a motor, you're not going to worry about the fact you can't run it on Tesco's value oil

I bet the V10 takes more than 5 litres though!

[Brianmoooore]

Think I read somewhere that the special oil required is something to do with lubricating the pump, because of the very high pressures it produces.
Then again, I might be talking complete rubbish.

[Andy_magic]

Modern injector pressures are extremely high, Landrover 300TDi's are 600 bar, The TD5 is 1500 bar and has provision for 2000 bar. Thats nearly 30,000 PSI

I guess it could be something to do with the pump

I worked (briefly) for a SEAT dealership (SEAT being part of VW as I'm sure you already know). The latest VW designed diesels do use a particular type of "common-rail" injection system pump. The engine is referred to as the "pumper"! I don't know the technicalities, but it is a fact that using the wrong oil in these engines can cause severe/expensive problems.

the 'PD' (pump-deuce) systems in later 1.9tdi vag group engines are sensitive to oil quality too-god knows why they made it so

the thng with modern turbo dieels is you can drive them like a loon and still get impressive MPG figures- my toledo gave 50mpg around town givvin it 4.5k in 1st,2nd and 3rd

[Andy_magic]

I had a 130bhp Toledo as a comapny car, very quick car for a diesel, really good stereo for a standard one too. Never bothered checking the MPG as I wasn't paying for the fuel

mine was oldskool 90bhp one based on the mk2 jetta platform-not as hot at the ole handling as the 2nd gen toledo (not as ugly either )

If some of you really want to go with this smelly, polluting fuel, then you can add LPG to a diesel as well.
It's not an LPG conversion, but more LPG assistance, in that the engine still runs on diesel, but LPG is fed into the intake air as well.
The result, if set up properly, is a marginal increase in overall economy, a 30% increase in power, and a considerable reduction in the asthma causing particulates that these things pour out.

I guess you're not a fan diesels then brian.

from my research into getting LPG fitted to diesels its rather expensive (Ԛ£1880 fitted) as it is apparently aimed at commercial vehicles.....

as for causing cancer-could stop making diet drinks...

i was just curious that's all.

as far as i know the vag system is not actually common rail. common rail means all injectors are fed from a 'common' high pressure fuel rail as in a petrol injection car.

the vag system is one high pressure electric fuel pump per cylinder. i'd be surpised if they're lubed by engine oil though!

maybe something to do with lubricating the turbo if vag use an unusual turbo design?
