How much do I damage my engine when driving top speed regulary?

Careful, if you spend too much time writing this shit up you might miss your bus.

>le busrider meme
I drive from germany to the netherlands once and back every week.
When I drive, there is usually not much traffic and no speed limit.
My shitbox does need about 8-9L/100km when going fullspeed due to beeing a econobox only marginaly taller than a kei car.

>>17094742
Is your bus ride about over yet? You seem very bored, must still be going.

>>17094742

How should I proof it?
Would a picture with timestamp, and my tachometer at high speed be sufficient?

I don't see why your 1.2l shitbox car with a redline where a literbike's powerband really starts would fare any worse unless you never changed the fucking oil, redlined when cold, and only used bottom of the barrel shit.

i used to do munich-frankfurt 5 days a week. now the question i have for you is whats the fucking point of an econobox.my 530d used to do same mpg or better than yours. high speeds might harm your tiny shitbox engine, but be completely fine for a larger one.

I can´t drive a Diesel here, since I have to drive across a Umweltzone where only cars with green stickers are allowed.
Also the small engine is the only thing keeping my speed at a reasonable level...

>>17094895
why not a 528i then?

The fuck are you talking about?

Just don't drive a pre 2007 car and your diesel will have a green sticker.

It's not because the car is a diesel when it doesn't get the green sticker, it's because it doesn't have the fucking particle filter faggotry but as I said diesel cars newer than ten years usually have one and therefore get the green faggot sticker.

>>17094948
Indeed, but as far as I know they will regulate that shit even more here soon.

>>17094948

You guys are fucked...

>>17094808

That really depends on the engine so stop spreading this shit.

There's something wrong with your car.

And no revving high doesn't hurt the engine unless you stay at redline.

Hitting the redline occationally and driving it hard for extended periods is called an "italian tuneup" and it's good for your car.

>>17094983
I think that's an UK thing. Here diesel and car tax was considered and it got stuck during initial stages in the parlament and the green party representatives are bullied to this day about it.

You're fucking talking out your ass.

He spoke about the FULL THROTTLE consumption.
A SUV or "sports car" does not consume this little while going vmax.

Aschaffenburg to Munich and back 5 days a week anon here.

I dont think going topspeed does much to your car as long as you keep up with maintenance.

Uruguay fag here. Our diesel fuel is as pricey as our gasoline, about 1.36€ a litre. And the import tax for diesel passenger cars is 115%.
Company trucks and cabs are exempt from this and only pay 5%.

>>17094983
Blame VW and yuropoors that fell to the diesel is ecological meme.

My car usually needs 4L/100km, when I drive at top speed I need 8-9L/100km.

>I usually drive slow for about 15 and then floor it for about 30 minutes while reving it at 5500-6000rpm, then I drive slow for about 5 minutes.
speaking about the engine: wear and tear is ca. proportional to RPM squared. I'd not drive like that if I was going to keep the car for more than 2-3 years

On the other hand kei-car and small engines like that aren't very pricey to buy/replace.

What are those numbers
I commute munich-wob every week in an a4 2.0tdi that uses 18.1l of fucking diesel at 220km/h (WOT)
Average is 10.5l according to the board computer

Broke 90k km this week, no problems that I know of yet (it's my company car so I don't really care/ check)

>>17097852
My car is one of the most fuel efficient gas powered non hybrids and can´t drive 200km/h.
I think this guy >>17097027 was talking about slower speeds or advertised fuel consumption.

>>17097050
Jesus fucking christ anon that's 800km a day
In a 545i at WOT, I suppose something like 150€ a day just in fuel?

Top fucking kek.

>>17097953
And I bet your average speed is still lower than mine.

>>17094812
You don't need to prove anything to these shitposting retards

>>17098015
I'm sure it is, but at least my gas prices aren't attrocious.

>>17098042
I still pay less for fuel...

>>17097953
europoor here.

that's about right.
imagine, even 10l/100km is really pushing it financially around here.

enjoy your v8 madness as long as you can, bro.

>>17097795
we never did, we imported them from Germoney and then Brazil back in the day. We used to build Twingos and Ladas from CKDs tho.
>>17097799
Leftist government who made it its mission to stop the "richfags cruising the ocean drive in diesel luxury cars" basically. Actually it was a cheap cash grab. The 115% tax functions more as a prohibition. Also they had banned the import of diesel engines no matter the kind but I think that's probably solved by now. You had a bus and the engine shat the bed? Tough luck, time to rebuild it even if it's more expensive to you than a simple swap.

Dude.
But then again if the majority of your commuting is WOTting the living piss out of that shit it makes sense.

The only other way to get the average so high in these cars is to permanently commuting 2km 4 times a day every day.

>>17098099
You're paying less than $2.15 a gallon?

>>17098106
Believe me I will.

>>17098120
I pay 5,85€/100km

>>17098130
because your shitbox doesn't need much not because your gas is cheap.

A properly designed engine should have no issue with sustained high load as long as it's under red line and your moving enough air.

The only thing that can hurt an engine is going from maximum high load and speed to a dead stop. Most OEM radiator fans can't push enough air to cool a modified NA ---> Turbo engine, since the turbine housing and core adds a lot more thermal mass to cool down. I wouldn't worry about it if this doesn't apply to you though.

Don't put a lot of load on your engine while it's at low RPM. That's actually worse than the same load at high RPM. The oil pressure is lower and the piston skirts have more time to contact the bottom sides of the cylinders. At low RPM your spark dwell time is also increased, and can in some cases decrease your knock threshold if your ECU uses a variable timing table.

>>17098115
Pretty much what I do, WOT on the autobahn and within the week 5km of traffic light races
245/18inch wheels aren't helping with the 160€/ week expenses for fuel

>>17098219
heh, well at least you're having the TDI since those are pretty much made for autobahn commuting.
a v6 or even v8 would probably sip twice as much with those wheels and wotting all the time

>>17098219
Smaller wheels -> higher topspeed
155/14inch here

>>17098262
that sounds retarded
unless you're talking about the measured speed in the speedo

>>17098291
Less whide wheels=less rolling resitance=higher topspeed

Guess why they get called prius discs...

>>17098241
>twice as much
I don't know, I had a 335i n54 a few years ago and took a picture doing 265km/h (indicated) with an indicated consumption of 16.5l, don't have it on my phone sadly

>>17098262
I know that lighter wheels with less air/ rolling resistance allow higher speeds but 17inch is the smallest I'd be allow to mount because of the breaks, also

Less wide maybe, but when you reduce radius you lose top speed. It's like using a lower gear ratio.

>>17098543
In my case I hit max power exactly at top speed in 4th gear.
So it is ideal.

>>17098564
Diesel BMWs are pretty common here in germany, you have to be fuel efficient at 200km/h.

>>17098564
I would gladly trade up my a4 tdi for a 520d
Comfy and fast commuting, probably even more fuel efficient, too

>>17094680
Your bearings will be hammered and possibly flake or crack apart and then you'll be in trouble. If the rods don't split and you don't drop a valve, you can expect the piston rings to start blowing by much earlier

>>17098562
Top speed would likely be higher with bigger wheels. Linear speed is the product of angular speed by radius, in pure rolling conditions (wheels aren't sliding).

>>17094680
>I usually drive slow for about 15 and then floor it for about 30 minutes while reving it at 5500-6000rpm
lol at regularly just casually driving around at terminal velocity.

>>17100027
Nope, I wouldn´t put any more power to the ground with a higher tire diameter.
That would have the same effect as my 5th gear.

I don't even run nice oil or anything, just SuperShit walmart 5w30 and a FRAM filter. Only had the car for 35k miles though.
