Skoda Octavia 2 litre Diesel Fuel economy.

decies

I must confess to really knowing nothing about fuel economy. My previous car was a mazda 3 1.6 diesel seemed to work out better.My skoda Octavia Elegance 14, 2 litre diesel seems to suck up the fuel. Any thoughts petrol heads ???

What year is it? My 2 litre 2005 Octavia MPG was averaging low to mid 50's on runs and it was fairly constant over the three years I had it. How are you measuring it?

Its a new Octavia bought January , not measured it properly, ( Whatever the easiest way to do that is) after a round trip of about 230 miles on motorway the indicator was about half way despite being filled up the previous day.

Your Octavia is hardly even broken in at this stage.

Give it about 45,000km and economy should improve!

Also , you are asking "petrol heads" about Diesel economy - funny!

Presuming it is the 140bhp version, that is the same engine that is in my Passat CC Bluemotion. I'm averaging around 50mpg so I would expect the lighter Octavia to do better.

There are a lot of mobile phone apps to track your MPG. Might be worth trying one of those.

I've got the 184 version of that engine (assuming you mean a 2014 150bhp) and get a pretty consistent 52 mpg out of it with about 5.5k km on it now.

The 2.0 diesel octavia at home drinks diesel when cold and can take up to 20 miles for the oil to get to temperature. I assume that it is not all short journeys OP. I could get as little as indicated 25mpg on a short 8 mile journey starting from cold on a frosty morning.

Also, as others have said, it'll take a while to bed in.

What kind of trips are you doing? Motorway runs or city runs?

decies

The typical short runs to supermarkets daily 2-3 miles etc a couple of 14 miles and 80 miles round trips at weekend.

The short runs will kill mpg especially in cold weather. Diesel engines take time to warm up and run at optimum efficiency.

I'm driving the 1.6L diesel version of '14 Octavia , currently at 9,000 Km so should be well broken in at this stage.

Filled up from empty last week, cost €62 (small tank) and now just under 800km driven and I still have not reached the red - so I estimate that it will work out to be approx 60 mpg. with a mix of urban and rural driving, mosting rural but a lot of breaking and accelation on bad country roads.

One thing I notice is that the fuel computer sometimes goes crazy and one minute you think you are running at 70mpg and then all of a sudden it drops the trip average down to 60mpg. But it seems correct on the long term readings.

That's what is killing it, the engine is not getting up to the correct operating temperature and so can't give optimum MPG.

How big is the tank, Is it the Greenline version?, think I read somewhere when I was looking at Superbs that the tank was 50 Litres not sure about the Octavia, my current car holds 70 litres. You would be filling up more often with a smaller tank.

The tank in the newer models is now 50l, down from 55l on the previous ones.

A quick Google suggests the Mazda has a 51 litre capacity so bang goes my theory .

I have read online that newer 2 litre is not as economical as older tdi seems to be the same with 1.6 tdi although there are bigger wheels on my new one 5 litres per 100 km versus 4.4 on last car
