Mk3 RS 162TSI fuel consumption...

[bobski]

I've always given new cars a sensible belting (ie, drive them how I normally would). Haven't had an engine problem with 5 new cars*, never had to top up oil, power has been good and fuel usage is always around the manufacturer's claim. I've read plenty of claims that a hard run in seals the piston rings properly, I don't think that means pinging it on the rev limiter driving out of the dealership. But I don't believe in treating them like Fabergé eggs.

Edit: *touch wood*

^ +1. What he said. I have had 5 or so and never engine probs (Except mid 80's Nissan Pulsar Turbo, but thats another story !). 3l Liberty was notorious oil guzzler and mine has been great past 200k. Never a topup between services required.

*touch wood* ^^2

I have a manual so can cheat somewhat but in the manual it talks about going up to a certain amount of revs until eventually getting close to redline in the first 2500km. To do that and keep within speed limits I went on freeways in pretty much 1st and 2 gear. In the DSG it would be harder, but guess you can force it to stay in gear.

U were doing freeway speeds in 1st & 2nd gears?!?! Fcuk me!!!

BTW - u can hold the gear in the redline while using manual mode in the dsg. It won't shift up.

It says to push it gradually to so many revs at each stage, the final being right out to redline. It's pretty much impossible to get it to 6.5k without doing it in a lower gear and getting to 100km/hr. Was only for a short stint. After that you drive it normally. No idea what the current manuals say but that was the TFSI engine. I asked the dealer when picking it up about any running in and they said no it's done at the factory. Checked the back of the manual and it had pretty specific instructions ala above, normally they just say don't sit at a single speed for too long, use cruise control, tow trailers etc for the first X kms.

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.

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 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.
