Another oil burner

[Two_Weeks]

Hi People,
I have been reading and consuming advice on this website for several months now, and when offered a free small car, made the decision to put some theory into practice.
I am now the proud(?!) owner of a '94 Fiat Uno 1700 na diesel. For anyone who hasn't heard of the Uno, here's a basic description:

• 1700cc non turbo indirect injection diesel
• Classed as a supermini/ citycar.
• Available with a 900cc petrol engine
• FIAT (Fix It Again Tomorrow) known for being unreliable and rusty.
• In 2006, it was quoted as the 10th most scrapped car in Britain.
• Cd 0.30
• No power steering
• No A/C
• Standard tyres 155/70x13.
• Previous owner says he got around 50mpg (imperial) I have been unable to determine the official figure.

Things I have done already -

• Replaced all tyres with taller 155/80x13
• Increased tyre pressures to sidewall max
• Purchased lowering springs (£20 ebay bargain) not yet fitted.
• Weight saving - removed all rear trim/ rear seats/ spare wheel/ rear wiper motor. May possibly remove passenger seat as will only really be used for commuting.
• Started using some hypermiling techniques

Future plans -

• Grille Block, possibly a front air dam
• Heated Fuel Filter allowing use of WVO/ SVO
• Smooth Body (Side Repeaters, Antenna, Centralise the single wiper)
• Wing mirrors replaced with cameras
• Mirror tint
• Modify existing wheel trims to be smoother.
• Rear Wheel skirts
• Front wheel arch gap fillers (shouldn't be too bad with lowering and oversize tyres)
• Synthetic Oil for engine and gbox.

I would have liked to have a baseline to compare the mods, but when I have a mission, I have to get on and do it, so I cannot say for sure if the mods will have a huge impact or not.
I still haven't even put any fuel in it yet, I'm running on the half tank that was in it when I was given it.

Thanks for the useful advice so far guys.

I think you would do well with a kamm back, and rear wheel covers. NICE FIND!!!!!

Sweetness! Light, small, and giant engine! That'll make pulse-and-glide go really well!

This style of spoiler may help your aero slightly:



Although you would never see enough gain to make up for the cost of buying one, unless you get it really cheap.

Better pic but I think this is from a mk 1:

First mpg estimate following a complete tank of fuel - 53.68 UK mpg (44.69 US mpg)

Generous use of coasting and low rpm gear changes (does 30mph in 5th no problemmo)

Of course having the taller tyres gives me 5% diameter increase which adjusts the mpg in my favour. I am doing a grill block and removing the passenger seat next and possibly swap to my lowered springs at the weekend if it's dry.

That sounds like an ecomodder's wishlist

Here's a quick GIMPed image of Luigi:



I added a Kammback (which could be longer), rear wheelskirts, and deflectors for the front wheelwells. The car looks like it sits pretty high, so lowering will give an even better effect. I didn't add smooth hubcaps, since the one's you already have aren't too bad. Those mods, along with the mirror delete and a bellypan, could probably reduce your Cd by 5%-10%, which would let you coast forever

I wish my beast could even get into the ballpark of this thing...

I know what you mean. My other car is a Landrover Discovery (26 UK mpg)
