OK.. guys i got nothing to do so i just did some calculation on i30 SX (base model) to see if its worthed to get a diesel or petrol and worthed to get manual or auto, in Australia

i30 Full Tank = 53L

i30 Petrol
Manual : 7.2L/100km = 13.9Km/L , Full tank gives (est) = 736.7Km's



Auto: 7.6L/100km = 13.2Km/L , Full tank gives (est) = 699.6Km's




i30 CRDi
Manual: 4.7L/100km = 21.3Km/L , Full tank gives (est) = 1128.9Km's



Auto: 6.0L/100km = 16.7Km/L , Full Tank gives (est) = 885.1km's


so if we drive for 2000 km's how much money we have to spend?

If price of petrol : $1.399/L and 1 tank full = 53L

Then
i30 Petrol Manual
(2000Km/736.7Km) = 2.72 Tank x 53L/Tank = 143.9L
143.9L x $1.399/L = $201.32 / 2000km

i30 Petrol Automatic
(2000Km/699.6Km) = 2.86 Tank x 53L/Tank = 151.6L
151.6L x $1.399/L = $212.06 / 2000km

If price of Diesel : $1.609/L and 1 tank full = 53L

Then
i30 Diesel Manual
(2000Km/1128.9Km) = 1.77 Tank x 53L/Tank = 93.8L
93.8L x $1.609/L = $150.92 / 2000km

i30 Diesel Automatic
(2000Km/885.1Km) = 2.26 Tank x 53L/Tank = 119.8L
119.8L x $1.609/L = $192.75 / 2000km

So if you keep your i30 for 2 years (average of 40.000km)
40000km / 2000km = 20 tank needed to achieve 40.000 km

i30 Petrol Manual
$201.32 x 20 tank = $4026.40/40000 Km's

i30 Petrol Automatic
$212.06 x 20 tank = $4241.20/40000 Km's

i30 Diesel Manual
$150.92 x 20 tank = $3018.40/40000 Km's

i30 Diesel Automatic
$192.75 x 20 tank = $3855.00/40000 Km's


Say if the price of

i30 Petrol
Manual $18.990
Fuel cost: $4026.40/40000 Km's

Auto $20.990
Fuel cost : $4241.20/40000 Km's

i30 Diesel
Manual $ 21.490
Fuel cost : $3018.40/40000 Km's

Auto $23.490
Fuel cost: $3855.00/40000 Km's


The different between Petrol and Diesel is $2500
and the different between Manual Petrol and Diesel is approx around $1008 (if Petrol at $1.669/L and diesel at $1.609/L).
Also the different between Automatic Petrol and Diesel is approx around $386.20 (if Petrol at $1.669/L and diesel at $1.609/L).

in petrol the price different between Manual and Auto is $2000
and fuel cost different is about $214.80 (if the petrol were at $1.669/L)

as in Diesel, The price different between Automatic and Manual is 2000
and the fuel cost different is about $836.60 (if diesel were at $1.609/L)


In my opinion

if you guys wanna drive an automatic might just get Automatic petrol cost is cheaper to run and more power (in hp/kW wise) also price is cheaper, unless you want to try the hyundai turbo diesel, lazy/cant drive manual and you want to use it more than 5 years because after 6.5 years its become break even with petrol

if you guys wanna drive manual, Diesel is the answer and also after 2.5 years its break even with petrol, and also its cheap in petrol also in maintenance, but if you want a power(in hp/kW wise) get petrol.

if you guys deciding which one to choose between automatic or manual. i recommend Automatic, the reason is that you don't have to replace clutch ( price of clutch is vary between $200-1300 plus approx $500 labor and average they have to replace every 80000km's, unless you a really gentle with manual they it might be last till 130000km's). but if u wanna fuel economy stick with manual, but remember u not gonna save alot of money ( approx $200-900) ,which not worthed because some of the good clutches price is starting around $900 mark + $500 labor cost and i know most of you guys want to keep your car at optimal level. and also modern Automatic car has a clutch in it , its cover under you warranty.

Importantly Always remember 100.000km's Diesel Motor will still performing the same way as you buy them long time ago (still Strong), as in Petrol 100.000km's most of the power is reduce over the years...

so think about it before you make up ur mind between petrol or diesel, think why u need petrol and why u need diesel...

and also do u need automatic or manual



Hint: remember Fuel prices is always risen.


thank you for reading this :)

Great read and well put together.

We chose the diesel over petrol largely because we will travel a minimum of 40 000 km a year. My break time is therefore reduced considerably.

Bob

Wow you must have been bored!!!!

Anyway I was interested in fuel cost so converted cost based on £1 GBP = $2.07

Petrol UK £1.08 = $2.24
Diesel UK £1.18 = $2.45

Petrol Aus $1.30 = £0.62
Siesel Aus $1.61 = £0.77

Basically us poms are paying an extra 72% for petrol and 53% for diesel.

Interesting, also, is that 72% is the tax levy on unleaded fuel in the UK.

Hi There Echocae,

Firstly, Welcome to the forum :00000732:

Secondly, Thanks for all your good work and calculations :liebe011:

Thirdly, I could almost hear your Italian Accent (am i correct/ my mum was born there) :grin:

Forthly, and i'm surprised Bob (tjaliwalpa) didn't say this as he's said it before the main reason for buying the Diesel (manual or auto) is the amazing torque which makes the car feel like its got a powerful 6 cylinder motor under the hood when cruising up hills on the highway (particularly with a full load on board) :grin: :grin: :grin:

If you haven't already you should try and get a test drive (preferably a manual)
then you will understand why such a high percentage in the i30 survey (separate topic) have gone with the diesel.

Regards,

Dazz
