MPG?

Post by ben_moto501 » Fri Nov 20, 2009 8:21 pm

Hi everyone,
I would be very interested if people could post some mpg figures? Together with whatever engine mods you have done. This is my first SJ413 and I'm a little shocked with the amount of fuel it uses!
I have a Weber carb fitted and a snorkel but otherwise my engine is pretty standard. I do a fair bit of road use as I use it to go to work and back everyday and I'm not the best at driving slowly but I've worked out a pretty poor mpg of 25?!? :shock: A £40 fill up of fuel only lasts me 200 miles!
Can anyone shed some light on this? Is this normal or is my right foot heavier than i thought?!

Thanks!

Ben

Mines the same mate. Iv got the 1.3 with a webber carb, and i was shocked at how much petrol it drinks. I thought it had a leak when i first got it :lol: Its only slightly better on fuel than my impreza, and thats seriously thirsty!! :evil:

yep 25mpg is pretty respectable, i get around 22mpg with mud terrain tyres and rocklobster, I have an all time worst record of 18mpg when my asian carb was running rich, before i replaced it with a weber, I did find i had better mpg with road orientated tyres, some thing to do with rolling resistance,

I run a 1.3 with a nikki carb, 410 t-box and 30" muddies. i get about 80mile to £20.

SJ's are not the most fuel efficient, combine the fact that they are aerodynamicly similar to throwing a breeze block down a wind tunnel.

my best fuel saving advice is sit behind lorrys, the drag created by a lorry will help pull you along, most noticable when going up hill.

my old 1.3 sammy was single point inj,, that was really good on fuel,, webbers are a bit like buckets, we ran a 2.1ltr beetle with twin 48s, ithink we used to get about 11mpg. but dans right, depends on what gear ratios, tyre size, engine mods, extra weight and its only a 1.3cc.
ive oppted to go 1.6vit in mine becuase of what ive just mentioned, it may be worth your while going down that road. my road car is a merc ml500 (5ltr v8) on lpg but its got great mpg, as the engine doesnt work hard.

So what do we think the answer could be? I hate the idea of getting under 30mpg with any engine be it the standard 1.3 or the Vitara 1.6! I used to have a Peugeot 306 1.9 diesel (non turbo) which happily did 55-60mpg! Has anyone fitted this engine into an SJ before? I know it wouldn't be as good mpg as that but even 35-40 would be a great improvement!!
Also you would benefit from other perks as it's a diesel ie... Lots of torque and the ability to swim better than the petrol engines!!

I am quite keen on this conversion so if anyone has put this engine in before I'd love to hear from you!!

Ben
