Hello again everyone, I am back.
Got a sweet deal on a facelift fl1 1.8.
All seems OK with plenty of work being done. No head gasket issues runs like a petrol should.
However I am getting 15 mpg. Not expecting td4 mpg but not less than half either.
Could somebody please advise where to start looking?
Can't be many on this simple engine.
I have proper diag, no error codes but can see plenty info however not sure what to look for.
Thanks
Paul
 
As it happens, I took my shiny orange 1.8k for a 400 mile round trip last weekend. Mostly motorway at 70, some A roads at 50. I had Torque connected and I averaged 34.7 mpg.
That is with a rattly cat!!

Yours sounds like it has a drink problem.
Any misfire? Run it and check colour of plugs for greyish white not black.
Leaks? Smell?
Take some lead out of your boot or the cars!!! :)
 
Depending on driving style and vehicle load, correctly running 1.8 should return between 28 and about 35 Mpg.
 
30 mpg would make me happy. No misfire reported or felt, that should show on obd.
Which plugs Andy?
Cat is brand new on this. All exhaust is new.
Can't smell anything tbh. I did put shell v power but nothing can explain 15mpg.
A compression test will be done very soon.

Spark plugs mate ;)

Pull them out and have a look at the colour.
 
Ah I have a set arriving on Monday anyway. Ngk iridium. That is when I'll do the compression test as well. Will inspect these as well.
 
It might be worth pulling the injector rail out too take a look at those too.
Compression pressure should be around 175 Psi, and should be within a few Psi of each other. Make sure the air filter is squeaky clean and not wet. Also make sure that no brakes are dragging.

Thanks Nodge. Will do most today, meanwhile I pulled some readings from pocket obd. Could an o2 sensor cause this?
There is something wrong with picture paste and upload...

I can depend on what distances you are doing - when I had my 1.8 I used to get around 18 mpg normally but that was because I was doing about 2 miles or less each trip so it was never really warm.
If I took it on a run it did do 30+ mpg though.
 
Not my case. I do 12 miles to work from steeton to shipley (west yorkshire) very little traffic as I go 10am. And it's a long bypass there.
Steady 50mph. Gets to 90 by the time I get to the bypass from a small road.
Surely something is extremely wrong. Reset trip, did 100 miles with half tank. That is 15mpg.
I am hoping to find something on compression today so I can return it tomorrow to dealer.
 
Upon removing the plugs, there was MUCH oil in cyl 4 and little bit on 1 and 3.
My compression tester is fubar, and very dangerous to use on K series because it uses a 19mm socket on base and I don't have any to pull out, almost got it stuck so not risking it.
However, I am not sure the oil is on the piston side of the plug or is just dripping from the rocker cover and when I pull them out drips more.
Need to make sure before sending it back. Have another compression tester on order.

The rocker cover is a mess leaking oil in front of the engine. By sealer you mean the rocker cover seal? Or on the cylinder head itself.
I am guessing if the oil would come from the piston rings, would show some blue smoke. That oil is not after the car being stood, as before I started I did warm it up a bit.
I am hoping it's the rocker because I have one brand new payen from my previous failures in life.
Thanks Nodge. It's not a fail yet, sparks are greysh pink and not black.
 
I have found the issue I believe. Propshaft had a split gaiter and lost all the grease. Did made some noises as well.
Also, vcu was quite stiff.
Sent it back to dealer, they replaced the prop (very nice) and now the car does not feel under-powered anymore and mpg seems fine, torque says around 28.
This will improve further with some iridium sparks and new toyo summer tyres :)
 
Good stuff. Yes a badly tight VCU screws mpg. Also, look at the tyre wear pattern. If bad the rears will have a fishbone type scrubbing.
Send a photo of the door panel that is damaged and I'll see if I can match it with a spare.
