Mk3 RS 162TSI fuel consumption...

[Gerrycan]

There is a bit of thing going in the UK where they take standard vehicles of the assembly, fit a couple of roll cages and thrash them around a track for 24 hours.
Vauxhall/Opel did it in 2013 with two diesel Astras and achieved a record 3002 miles.
Mazda have just done the same with three Mazda 6 diesels and achieved 3293 miles. New record but in a different engine size category.

Point of the story is no pre-running in, no reliability issues (whole point of test) and apparently no engine oil consumed.
Are we over thinking this running in lark?

Edit2: sounds a bit harsh. I'm just trying to get at 'the manufacturer would have done it for a reason. If they could have gotten better economy with a taller gear, they would have done it'

Actually they have done it. My A3 TDI(e) was specifically designed to improve fuel economy. 1.9tdi, manual, hub caps instead of alloys for wind resistance etc. (yes getting rid of hub caps and ECU retune soon but that is another story)

The 2008 A3 has a taller 3rd and 5th gear than normal, they are not evenly spaced, so the revs drop at suburban and highway speeds. It sees about 1800 rpm in 3rd at 60kph and similar at 100kph in 5th (no 6th gear). The A3 sees average about 4.5l/100 combined. A highway run drops to the high 3's L/100. Although fully loaded with a bike on the roof (bike had a bike bra on) and a stiff south easter from Adelaide to Melbourne, I couldnt get below 5L/100. Very annoyed. But still last tank was 75% highway and I got a touch over 1000km from 50L the tank. Overall, Prius eat your freaking heart out.

But RS I drove as per the owners manual for the first 1500km with no high revs and no constant revs, then at 5000km it got new VW/AUDI branded oil and new filter. That stuff aint cheap. Now I get low 6 L/100 and a trip to Port Fairy and back from Melbourne averaged a tad over 5L/100. But this is a diesel so it doesnt mean much in this thread.

But I still drive 'enthusiastically' within the speed limit.

Oh and as mentioned as far as speed limits in Oz, the road north of Alice springs is back to no speed limit for about 300km.

Yes the green line version has taller gearing, but it isn't substantially better than a std version with the exact same setup.

Not doubting your figures are impressive though

I drove most of the hume/M5 from the dealer delivery in Campbelltown to Hurstville just using the first 3. M5 was 100 at the time and I could over-run down to 60 then accelerate at half throttle up to 100 as there was no traffic (for a change).

The next day I drove Hurstville to Ulladulla & return with all the family on board using up to 4th. The were starting to turn green with the slow-down speed up style so I had to stop that.

I had our 6mth old in the back when I did all my runs, she didn't seem to mind. Had to do a trip to Geelong for work, that gets annoying but I just went between 4-5-6th gear and went up and down from 100 +-5km so it wouldn't sit at one speed for too long.

Managed to jam 52 litres in the tank today. Still had 30km left to empty before i filled up.

I think its pretty conservative with empty estimates, the tank is 55L but I've never got close to getting that much in there.

Total k's traveled?

[Dzl_Dubba]

660km and the tank is 50L in the new RS

7.5 l/100 seems fair

[GTR27]

New tank is 50l, but it's amazing how many on briskoda fill 50l each time into it.

Previous model was 55 and you could do a bafflectomy and get 60l in. It would have been nice to have a larger tank, so 1000k was achievable in petrol models

[Dzl_Dubba]

Thats my only criticism of the new octavia. Should've kept the 55L tank.

There is a guy in WA with a mk7 Golf who claims to regularly put more than 57L in its claimed 50L tank. I know with my mk7 Golf that I put 50L in when the gauge is halfway through the red and with around 60km still showing on the range display. It's a 90 TSI and it's easy to get over 1000km from a tankful as long as it doesn't involve too much urban work. I'd imagine the Octavia is the same.

OTOH, heaps of posts on Briskoda about driving untile the DTE reads 30km & only fitting 40L in.

On my Mk2 the "refuel now" warning means I've got about 8L left

[woofy]

Strange, guess they wanted that 5L for something else, but I always found the 55L wasn't quite enough for me and wanted 60L.

When the warning comes on in a mk7 Golf it takes 48L. I have now done 54,000km in it already in 16 months and it has happened more than a dozen times and is consistent with that reading. It always happens as the gauge reaches the red. It also takes 33L when the gauge is showing half full. It will have done around 650km at that stage. It doesn't even leave the full mark until it has done over 250km.

Just another one of those variations between the brands I guess.
