Advantages v disadvantages of a diesel!!!

ADVANTAGES:

1) err, err, slightly more mpg (but more frequent oil changes and servicing initial cost more than cancel that out unless you do about 100,000 miles per year!) 2) err, err, ??? Anyone???

DISADVANTAGES

1) more expensive 2) heavier 3) slower (unless turboed but then you can turbo a petrol engine too! And then the diesel is last again...) 4) LESS torque size for size unless turboed (see 3) than petrol. 5) LESS power 6) Noisier 7) Tiring drone to drive 8) Tiring engine braking 9) Smelly fuel 10) Diesel on hands, feet, carpets, etc.when filling up 11) Engines wear faster due to: a) dirty oil faster due to soot getting past pistons which is abrasive b) Permenant WOT condition means the full 23 to 1 compression is forcing the pistons sideways in the bores and loading the crank madly even at idle! 12) Heavier battery needed and bigger electrical load on starting means starters and batteries last less well. 13) Less rpm band, more gearchanging so harder work! 14) Sounds like a truck especially when cold due in part to 11b 15) I dont like them! 16) need servicing twice as often due to 11a

  1. Cheaper.
  2. Stronger. (Well, it is on my car anyway - no pesky electrics to worry about.)
  3. Amusing squid feature.

But then my priorities are probably a bit different to yours.

What does WOT mean, wide open throttle?

Thanks to diesel cranks, some engine power upgrades are easier!

it's also more expensive to run fuel wise :)

Name one? Do you realise that for eg VW use the same basic motor for the diesel or the petrol?

Only in the most brutal sense. Certainly not 'pesky'.

I have 2 very similar cars one with a petrol one with a diesel both produce the same peak bhp and the petrol is a lazy 8v with a nice wide chunk of torque there's no more gear changing in the diesel then the petrol despite the diesel being a tad heavier.

They are good in 4 x 4s where you need long range and the ability to drive the thing up to the windsreen in water. 1000ks out of a tank on a Defender is pretty bloody good going. Other than that they are shit.

But I bet the diesel has the benefit of a turbo... To make things fair you have to fit one to the v8

Thats Advantage not Advantages ;) Basically, unless you can get a cheap one for the same price as a petrol one, and you have no intrest in cars/driving/fun/life just what's the cheapest to run - then a diesel is for you.

Good point. That should go at the top!

3) drive well under water!

Since gay men are typically comfortable with their penis (*), what are we to infer from that statement?

(* It's just that they're comfortable with other people's as well.)

Or LPG or hybrid electric.

Whats wrong with clockwork?

Er - isn't the significant change from indirect injection to insanely high pressure direct injection?

AFAIK that's what makes the modern ones so economical.

(I'll grant that all the tuning, turbos, etc giving the high power outputs is more evolution)

It's hard to stick a turbo on it. Dragging this off topic I saw an article of some nutter sticking a supercharger on a Prius.

Are you sure? I thought it was a diesmell.

Dunno, but my old transit 190 diesel had direct injection and it was crap...
