Getting fantastic fuel mileage in my 2003 1.6 Golf

Nephilim Wolf

I got my 2003 VW Golf Highline petrol engine tuned recently because of emissions. I wasn't cheap and I'd rather not say how much it cost. The engine is even quiter and runs like a swiss watch. At the moment I've done 498 miles (not kms) so far and amazingly there is still at least another 100 or 150 miles to go before the tank is empty. There are a few little rattles but the car is very very reliable and always starts in the morning. So anybody else getting this kind fuel economy in a simlar 1.6 engine?

What do you mean by "tuned"


Also, how much did it cost

What sort of driving do you do?

GustavoFring

What were you getting before this magical process?

Great Scott!

Golf tank is 55 litres I think. 12.8 gallons in old money.

If you get 650 miles, You need to go to Germany and tell VW they've been wasting their time with direct injection, 16 valves, turbocharging, regenerative braking and stop-start. You're getting 51mpg and the future of petrol engines lies in the early 90's 8 valve 1.6 engine.
Your tuner fella has a bright future. This could solve VWs diesel woes.

What I mean by tuned is the pistons and piston rings and head gaskets replaced. And believe me it cost quite a lot. I'm not sure if this increases horsepower though? I do some motorway driving and driving to work which is only a couple of miles. I went down to wexford recently the scenic route actually, and I was doing a lot of mileage between Kilmuckridge to Gorey, New Ross and Enniscorthy. When I arrived down to my best mate in Wexford the odometer said 120 miles and obviously the petrol guage only moved a milimeter or two.:D Also because the was engine redone, my friend thought my cars engine was off even though it was still running. I only have to fill up about every month and a half which is great.

Thanks it is a very good car indeed. It's not a 90's car though, it's a very late 2003 1.6 16 valve engine. Also when my car is in traffic the engine is very quite and the gear stick is as steady as a rock.

Fill the tank to the brim and recalculate it. Do this another two or three times and you'll get a far more accurate reading.

Get back to us when you've done that and we'll be able to comment better as we'll have more accurate information.

this backs up my theory that the last good car made by any company was the '97 vento,

which does 9 miles to the euro

The engine (technology) is from the 90s.

Tuner installed extra fuel tank. Brimmed it with 100 quid of petrol and that is supplying engine 50 / 50 with main tank.
Tuner will have left country with your tuning money by time you find it.
I hear vw are working on a similar system for the latest range. It will allow them to claim 100 mpg across the board.

''Filling the extra tank with vw branded motion fluid is a service procedure relating to fuel system lubrication only and should be topped up weekly by your vw dealer. If driving in a location remote from authorised dealer network, unleaded petrol can be used instead of vw motion fluid.''

I disagree, the XR3i was much better. Don't see them around these days for whatever reason.

Del2005

The tune up was an 80l tank.

OP have you informed your insurance company that your car is heavily modified?

sonique 2016

i'm afraid the xr3i is a thing of the past,

you would see a few on donedeal, a few for sale in england

Is the OP audi12's brother?

Are you sure he didn't install a tdi?!

I'd say someone reset the trip computer after 200 miles and forgot about it....

Getting engine redone on a petrol 2003 golf was a poor life decision.....and trying to convince yourself it's suddenly a miser on fuel when it just isn't, makes no sense.....drop car into a mechanic to check the odometer or wheel size....

Why would he do that? As he said a few posts above yours he only replaced/reconditioned parts

Typical high horse crap

He's a pure mathematician when it comes to calculating mpg, reminds me of the people that say they get so many miles to a tenner :rolleyes:

I hope this is all satire.

Getting a 1.6 16 valve petrol engine "tuned because of emissions". The emissions only affected new cars, not those with engines from 1998.....

And also paying for something like that to be done to a car worth around 1500 euro.

Surely must be satire.

Maybe he go hold of one of those gadgets that plug into cigarette lighter. 20 percent instant improvement in fuel consumption

After I disconnected the battery on my car, the fuel needle showed full. I could have been caught out had I not realised that the car should have been empty.

To be fair it dropped extremely quickly, over the course of maybe an hour or something. My guess is that the fuel level meter sends an analog voltage, and it automatically recalibrated over a period of time.

Must have used one of these ans 3 of those gadgets.

Somebody correct me if I'm wrong but I'm pretty sure the op's 1.6 engine is an eight value single cam unit.

No, they brought out a 16 valve version of the 1.6 before the Golf Mk4 keeled over and died. Then when they brought out the Mk5, they went back to the venerable 8 valve unit, which incidentally was also available in the Mk6 for a while!

I know a guy who has a 4 way one of those and 4 gadgets plugged In. He actually sells petrol back to the service station once per week.
FACT.

Op I seriously think you are counting wrong.
Do a brim test and you will see your figures aren't correct.

Definitely not. It's just the way I drive. I block change a lot, and I just drive very economically. I also dhift to fifth gear asap.

Simple things help mileage in all vehicles. I run 40 psi in my tyres. Wear pattern is good. Take extra rubbish tools etc from the boot.

Over inflating tyres, not recommended. You have less contact with the road when braking also uneven tyre wear. For the amount of fuel saving it isn't worth it.

Exactly. Makes the car very uncomfortable especially in the back.

I'd have thought that putting the car into 5th as quick as possible would just put more strain on the engine?

Nah,

I only use 5th, go through clutches like there's no tomorrow but 1,000,000mpg covers the cost easily.

Top tips: drive economically and you can rip apart the laws of thermodynamics.

Europe as well, the last of them had a 1598 cc engine (as opposed to the 1595 cc the 8 valve versions have). The 16 valve models come from the same engine 'family' as the 1.4 which, apart from the lack of power at just 74 bhp, was also well known for its fondness of oil amongst other things!

Anyway, back on topic, this surely has to be in the nominations for thread of the year:D?

On the mk6?

GustavoFring

That engine was well gone by then. It was the 8v in them. The diesel does have the same cc as the old 16v engine mind if that's where the confusion is.

The 16 valve was for the Mk4 only, they went back to the 8V for the Mk5 and Mk6. Of course, the FSI is a different kettle of fish, and that was Mk5 only.

GustavoFring

That's 16v one wasn't that bad to drive tbh. Herselfs old fella had one in an octavia as a runabout, 180k miles on it nearly and never gave any real hassle from new. Didn't do 50 to the gallon though:pac:
