I'm back. Car has had a service, new tyres, new exhaust system due to corrosion and during the service the brakes were cleaned and deglazed. They were in good condition. All filters changed, Pollen, Air, Oil, Fuel. Oil changed and coolant changed. I drove from Plymouth to Brighton and back again. Got just shy of 300 miles to 40.12 litres (33.6 MPG) using Tesco Momentum up and Esso's equivalent back. Drive was hilly, some a roads and roundabouts etc. What cable do I need for VCDS so I can monitor and log some more details to see what the engine is doing? Also on this forum someone advised another owner of this model they could use VCDS full version to change the fuel trim whilst cold to potentially save some fuel around town/short drives. Any advice on either of these? Cars running nicely with the service, new tyres and exhaust system, just be nice to get fuel economy a little better!

Just came to post a little update. Not sure whether it was the spark plugs in the end or the bottle of redex and e5 I dumped in but I had a few poor MPG runs so dumped the redex in with some e5 and ran it from full to fuel light. Yesterday I filled the car up with e5 and drove to Cardiff and back with about 50 miles of City driving in Bristol Taunton, Bridgewater and Cardiff itself. I was completely shocked when I got past the 180 mile mark and the fuel gauge was still midway. Ended up going 335.4 miles before I decided to fill up, it was in the last notch before the light so still had a little way left. Fill up was 37.57 litres of E5 for a MPG of 40.58. 40.58 MPG! Compared to 20.4 MPG before. Excuse the dust/dirt, cleaning her was not a priority until now. Even though thats nearly double I will be having the car go through a full, yes full service (minus plugs) next week. Certainly over the moon with the improved MPG which has nearly doubled, which is also concerning, where did all that fuel used to go haha!

No fuel additives or anything other than the E10 rubbish from the pumps. The old ones were definitely a yellow colour, I did Google it but it just pointed to excess engine temps which I've not noticed.

I got the Halfords advanced set when I had a VW Golf 1.8T that had a FMIC that kept popping tubes amongst other things. Haven't used it in about 8 years so took a few minutes to work out which end of the ratchet did what 😂 Will do!

Awesome sounds good to me, I love the car just haven't had the chance to fix the niggly issues. Will set aside some time. It may not be a vrs or expensive car but she does what I need her to do

I did figure it was worth changing anyway! I'm now wondering what else has been neglected on her!

Fingers crossed! When I got the car the wrong brakes had been put on and that caused issues during a full multipoint service, wouldn't surprise me if they had the wrong plugs. These are definitely correct ones!

Nothing but the gap was at least 2.5-3x the gap of the new ones. I guess I'll see!

I'm no expert, but I changed them. The gap on the old ones seemed about 3 times as much but I would have expected to feel the engine misfiring or something if the plugs were bad surely? Pictures attached for someone better than me to tell me if it was worth while or not! I'll monitor fuel economy.

Brilliant will pick some up now, the service was done by a family mechanic, he passes back all the old materials so I know fuel/oil/air filter, oil and coolant was done but sparkplugs were left. Will post update

Just out dog walking but will do in about an hour. Is it worth me just replacing the 3 plugs as it's not expensive?

I drive according to others very conservatively, I'm always anticipating what's ahead and never close to cars in front etc. But understand what you mean. I tend to coast a lot which I'm not sure is either good or bad for MPG. I'm going to change spark plugs and clean the throttle body and black sensor on the back today, it's £3.50 a spark plug and like £4 for a carb cleaner so worth trying.

Apologies it's a 1.2 MPI, not sure how to edit the title on phone will look when home. 1.2 3 cylinder MPI, not sure where the "1.3" concept came from. I'll answer the rest shortly. Last refuel was 40.55 Litres, I did 44 miles each way (88 miles) Plymouth - Exeter on the A38 doing 60 Mph and the rest was urban driving (94 miles) for a total of 182 miles. Urban driving tends to consist of a 4 mile drive through city center each way (8 miles daily early morning), no traffic early hours, a few stop/starts for traffic lights, fairly flat terrain, 1 hill midway. I worked this out to be 20.4 MPG. I know it's a small engine car I just figured that was on the low end, I've had a lot of cars growing up and this one feels the worse.

I love the car, just not the MPG haha 😆 Hence I'm here. It's a nice car, nothing special but does what I need it to do!

Good Afternoon, I have a 1.3 MPI and for as long as I've owned it I've only been getting about 170-175 miles to a full tank. I've researched here and everything from brakes binded, temp sensor, maf, exhaust sensors etc. Not sure where to start. It had a full service last year when I bought it, new air filter, oil, oil filter etc. Brakes don't seem to be binding, car rolls freely and no jerking or stuttering. There's no visible temp sensor on my car, there is a blue light that goes out once the car is "up to temp". What's the best way to proceed from here? I've tried to look after the car, tyres are all as new, correct pressures, serviced yearly. Thank you!
