Topic: Real-world fuel consumption

[quadzilla]

Like running a fan and using balancing damper to slow it down to the airflow needed.

Cambridge - Warwick -- Mostly 401/402 into a headwind with cruise at 118 kph = 6.1 L/100
Warwich - London -- All secondary roads with a tail wind, rush hour/construction traffic once in London, cruise set at 90 kph = 5.1 L/100
London - Cambridge -- 401 with a quarter wind, cruise at 118 kph = 5.9 L/100

The Rolla is now on 16" X-Ice Snow winter tires which drive very nice and where slightly quieter than the 18" Michelin Prime (?) stock tires.

Primacy is a common Michelin OE tire. Could be Premiers too?

Nice numbers cruising at close to 120.

Went into the garage to check and the tires are the Primacy A/S.

I think the f/e is what I'll be getting and I'm happy with that.  Might be able to squeeze another tenth or two in the summer, who knows.

Awhile back I bought a 2010 F350 with the twin turbo 6.4 diesel, it had all its emissions intact and bone stock. It would average 18-19L/100km in everyday use. I drove it to Calgary back in September to the powerstroke Doctor for a full delete and tune. The truck averaged 10.1L/100km going back to BC and now on my second day of just mixed driving it’s getting 13L/100km average. Amazing how bad those early DPF/Regen systems affected fuel economy. Even when these were new they were getting 20-30% worse fuel efficiency than its predecessor. The original system was operating as designed with no errors or malfunctions.

And talk about power….wow, huge difference.

Wow, my FIL had a F250 of that generation and loved everything about it but the fuel economy.  I'm guessing that these are quite sought after nowadays.

The 6.4 was only offered 08-09-10. They were extremely problematic due to the emissions system. It’s definitely not the most popular Ford diesel truck. Put it this way….if this Ford I have were a Chevy/GMC I could easily get $10,000 or more for it. When they work they work, when they break you’re savings account will cry.

I assume deleting the emissions stuff significantly improves the reliability.

100%.These engines had a awful DPF/EGR design. In regen (burning off soot trapped in the DPF) the system would inject fuel into the rear two cylinders during the exhaust stroke raising the exhaust temperature to point where the soot is burned off. Trouble was, that excessive heat caused all kinds of problems; cracked pistons (in the regen cylinders) failed EGR coolers, failed oil coolers, coolant cavitation, cracked heads, cracked turbo up-pipes, not to mention the horrific fuel economy that these would get during an active regen (think 6-8 mpg)....it was a trainwreck. My truck only has 80,000 km on a drop in Ford engine so it was worth deleting to allow it to live a decent life.

This engine was known as the 150,000 mile throwaway. If left with its systems the engine would rarely live longer than that. Deleted, many have double that mileage and more.

What a nightmare.

No chance I would have bought my TDI without the emissions warranty. That said, there haven't been many grumblings about DPF failures on the Mk7 Golf.

It seems the light automotive side really has stuff figured out. I rarely hear of issues in VW, MB, Audi diesels. My cousin in law is the diesel tech for a Benz dealership, he said oil leaks are the most common problem he sees. Even in light and heavy trucks things seemed to be much better than 10 year's ago.

Averaging 18.5L/100km city in the W12 Bentley. Worth every penny...

I don't see oil leaks at the shop often, but DPF, NOX sensors, etc. are very common failures for MB Bluetecs. The ML350s/R350s are total junk to own, and the E250/GLK250 are very close behind.

They certainly show this at auction. They are almost always sold red light (as-is no arbitration) and never bring much money. I’ve been tempted many times. I owned a 2008 Cherokee 3.0 and aside from a catastrophic fuel leak while warming up on my driveway it was trouble free and very efficient.

And that Bentley isn’t doing too bad! I’m sure hearing the W12 growl is worth it.

The starter noise is properly sweet. It's like "whirrrrrrrr" into a "vroom". Sounds great.

Yea, lots of V10s are like that too.

Neat. I've owned a V10 (Touareg TDI), and driven plenty of R8 V10s and Huracans, but never really noticed.

^^I've noticed on the Audi S8 when I was testing them.

Awesome! Always wondered why V12’s had such a starter sound. I once fired up a V12 S-class at an auction and at that time thought maybe it had low compression.

I like odd sounding starters for some odd reason. Old V8 Mopar products also had a really odd starter sound. I’d own one just to hear start lol.

I've heard various reasons.  It's because more reciprocating mass requires a smoother start.  These starters run the engine at a specific and constant RPM....the ECU then wait a few beats for the oil to circulate....then adds fuel and ignition.

Some of these use gear reduction starters too.

I also heard a manufacturer say they do it because it sounds cool and people like it.

I've put about 3,500km on the '09 LS 460 since getting it on Halloween night. It's averaged 13.1L/100km on Fuelly, mostly city. Plenty of sitting around for days on end, lots of cold starts and small trips.
