Congratulations!

I'd recommend you sign-up at myKIA (it is also an app) and you should be able to download a PDF of the manual for your car. Meantime, here is what it says in the manual for my JD generation Proceed (also with the G4FJ engine):

11491


Once you are clear of 'running-in', and you are ready to drive normally, something you might encounter is the protection KIA has built into to the ECU when the engine isn't up to temperature, strictly limiting boost (far be it from me to suggest anyone who finds it lacks any sort of mechanical sympathy!).

The G4FJ will run happily on 95RON ( I haven't tried the E10 version yet though). 97, 98 and 99RON makes no discernible difference in my experience, save perhaps a slightly better idle. You may well notice the G4FJ can be a bit erratic at idle, a known problem. Of course, I'm speaking for my older version with a manual gearbox, things might be different with your DCT equipped latest version.

An imponderable and controversial benefit though from using something like V-Power with it's alleged greater detergent level, is delaying the onset of carbon build-up in direct injection only engines...

I can attest to the very underwhelming performance of the 1.6t when it's still waking up. I like to think I have a bit more sympathy these days but I don't think the software restriction is a bad idea....

Fuel wise, it runs fine on anything. I only used 99 ron when I got mine but then started doing mileage so dropped to standard 95. I might run some tanks of vpower through it though, just in case it can help with the gdi issues. I like to think it runs a little sweeter on the higher octane stuff but I'd not argue it for long.
According to my regular tesco pump, I've been using E10 for a couple of weeks now. If it is E10 already, I've certainly not noticed anything different but they may not be selling full spec yet.

Thanks for the reply’s that’s great!I’ll run it on 95ron and take my time for the first 600/1000 miles ,just curious now what sort of mpg do you get out yours ,the dealer told me mid to high 30s which I thought was acceptable for a car with a bit of punch in it and a auto .

I know quoting mpg for anything bit your own personal circumstance can be misleading, but I'm going to do it anyway, seeing as you asked!

Over the last three and half years (129 fills) my calculated mpg has been 38.0; the trip computer over that time has averaged a reading of 39.3mpg. Yes, I really am sad enough to keep it all on an spreadsheet.

[Bear in mind this of for my previous generation Proceed; broadly similar weights and CdA, but mine will have slightly less economical mapping you'd imagine (Euro5 against Euro6d), but you will benefit from the 7th gear on the DCT which is much longer than my top 6th. The DCT will in theory be will more economical in most casual driving].

As with everything, it depends on your typical driving. I do boring motorway commutes for most of my mileage, and I tend to just stick the cruise control on and go with the flow, overtaking nothing but HGVs. A jaunt up the M1 the other week resulted in a new record for my Proceed, recorded 48.0mpg over 208 miles (photographic evidence available!), so it can be done.

I think that perfectly illustrates how much of a range you can expect from this engine, depending on how its driven. I think it's because I have big feet, it's harder keeping all the weight off the go faster pedal 🤔

Ah yes, my Size 8s and my Italian suede driving shoes are probably the reason. If I drove everywhere with my site boots on I might be able to get it under 30mpg!

By way of contrast to that very surprising 48.0mpg, the worst I've had on a tankful was 31.6mpg (calculated). That was during lockdown when I wasn't driving more than three miles from my house.

It’s got potential of being better than I thought then I’ll happy with anything in the thirties
If you are happy in the thirties, you'll be OK, no matter how you drive or what your shoe style and size is.

We look forward to your brim-to-brim fuel calculations!

Does not start till 01-09...

Local Sainsburys has put a sign on all pumps to that effect.
I guess it must be a highly specialised job to add that E10 sticker to the pumps, hence why they have been doing them so early :rolleyes: 😂

I would assume there's a twenty page risk assessment and similar SOP! 😁
