Fuel efficiency of the 1.2

[chimpsinties]

I bought the 1.2 thinking it'd be cheap on juice.

I tend to get about £40 in the tank on a fill up and that lasts for anywhere between 300-330 miles if I'm using motorways = 35mpg

but the other day I put £20 in and I've barely got 100 miles around town = 22mpg

This seems pretty bad.

I'm sure I used to get about 300 miles from £35 in my old 2.0L 16v car (MR2).

Is it normal for a 1.2?

Could the chavvy 195/50/15's that the previous owner put on it be making a difference? Didn't it originally come with 165/65/13's or something?

I serviced it a Crimbo and it seems to be running well. Is it just underpowered for the size of the car so you have to rev the titties off it to get it to go anywhere? :evil:

i got better mpg from my 172 than i got from my 1.2 16v they are terrible.

punt it for a diesel i get 65mpg in mine

 

[Budgie]

You're obviously revving it too hard..

I used to get 400+ miles to £40 in mine. Regular driving. Nearer 450 on the motorways, and neither of those, was I driving particularly gently.

 

[Cliotoby]

300 miles if i was ragging it now and again, 350 on mways not that i ever did that kind of driving. no less than 29mpg EVER and no more than 48

 

[James.f]

Try giving the car a service, might improve your mpg,

I used to get about 37mpg in my 1.2 16v. when revving hard it went down to about 33-34mpg, mine was regulary serviced tho

I don't rev it that hard. Usually I'm just pootling round Sheffield in traffic. That probably doesn't help but it's also dead hilly round here so you're spending most of the time in 2nd or braking. :dapprove:

I must admit, I kind of wish I'd gone for the 1.4 or 1.6 now. I think underpowered cars are just asking to be pushed a bit cos they just feel so sluggish. With a bit more power you tend to take it a bit easier.

 

[Martin_172]

why would servicing it make the mpg any better?!

 

[alex-avfc]

Once warmed up I used to boot mine everywhere and it'd still return 38+ mpg. I actually found keeping it below 3k or whatever didn't make any difference at all to mpg.

erm the diesel if ur worried about fuel consumtpion lol

Didn't you read the original post?

[MK3]

I'm averaging about 32mpg. I'm sure i could get more, but i've got too rev the ass off of ot to get it to move lol

If you've got good spark plugs, nice clean oil, a clean air filter, that's got to help fuel efficiency a bit.

 

[Martin_172]

cant really see it if anything the dirty airfilter will give better mpg lol

 

[SC03OTT]

If you are stop starting and never making it out of second, that is the problem.

 

[chimpsinties]

Why?

 

[Martin_172]

less air into engine = less fuel = better mpg + less power. wouldnt make that much difference btw!

 

[fearless]

I have never got it below 32mpg. Even if it lives on the limiter for a few days. Have regularly had 50mpg on motorway runs. Swings and roundabouts I suppose.

 

[Marcus---]

mines currently 30mpg in my 1.2....it sucks but its city driving, stopping and starting constantly only ever in 1st, 2nd 3rd, filling my car atm cost me about 50 quid aswell

 

[Tom_90]

the 1.2 trains us so we know what mpg to expect when we inevitably (sp) buy a 1*2

 

[chimpsinties]

Less power would probably mean you'd floor it more. More peddle to metal = more fuel.

Haha :lolup: It's all practice for the big game

 

[RobCrezz]

Not exactly.

If the air filter is clogged up, then the engine is going to have to do more work to suck the air through it, you will still get roughly the same amount of air drawn in though.

 

[Harpham]

Im currently getting 50.2mpg out of my 1.2

I think I get around 400 miles for £25-30 of petrol (thats my weekly fill up rate)

 

[Aluco]

Try driving a 172 round town, unless I literally roll to work in neutral (uphill so I can't) I get 200-220 miles to a £45 tank.

How can our two cars be so different? Mine is an X Reg. This just sounds too good to be true. I'm jealous

Ouch :dead:

no it wont, the driver will make the engine work harder by giving it more throttle, at 10% throttle you will get LESS air with a dirty air filter, which in part the ecu will put less fuel in to match the air.

the engine wont "work harder" just to suck air in

Mines a 53 plate... I drive like a grandad though! Change gears at around 2000rpm and never thrash the car. Ive only been over 3-3500rpm when ive been on the motorway doing around 70mph lol (which is hardly ever)

 

[Aluco]

Ouch :dead:

To make it worse I do about 300 - 350 miles a week LOL.

s**t the bed.!! Have you done any engine mods to the car??
This doesnt sound too good to me, as im thinking of getting a ph1 172

ITG filter. Lol.

TBF I ragged it's arse off sunday night to try and stretch it out a bit and it's on 36mpg this morning when I got to work. I was driving like Jesus on a sunday though.

 

[Harpham]

hahaha.. thats ok then, im going to look at a couple of 172's tomorrow!
Im hoping I can keep the fuel costs below £50 a week!

 

[Aluco]

Depends where you drive on the motorway if you wanted to you could get 450 miles to a tank. In town if you're even slightly careless 200.

 

[Ronnie R]

Lol same as me.

I got 190miles last week from a full tank, £47ish a tank now, not even V-power.

MPG normally around 22-24mpg, I've seen it drop to 18.1mpg!!

 

[Aluco]

I've stopped using vpower, simply can't afford it haha.

 

[Ronnie R]

I think it's about 1.19-23 round here.

Tesco's/Sainsbury's is what I use now lol.

I've been thinking whether to sell up and go for a Polo or something, I think I'd regret it though so I don't think I will lol

 

[Aluco]

Selling mine after summer anyway lol. Not getting anything else though, no car ftw.

 

[Ronnie R]

How come your selling up? My girlfriend is taking her test soon, so soon she will be driving. I won't need to use my car no where near as much.

I could get the tram to work and it would cost me £40 a month, but I chose to drive n spend £200 lol, I seriously hate the tram

Moving to the land of the rising sun for a year to teach.

[Renshaw]

i'm getting 30mpg in my 1.2 dynamique. i used to get 45+mpg regularly and very rarely dropped below 40mpg.

i think its to do with the Lambda Sensor ...but im not sure which one (aren't there 2 of them?)
