Technical Running in: Discuss

I have heard a story of a kitcar owner who thought he would run his engine in......he put his car on axle stands, started it up, put it in gear and let it run at low revs while he went and has his tea.

That engine didn't last long.

Fully agree with LittlePip's comments.

well i'm talking about new engines here i take it our mate with a kit car had his engine rebuilt in which case there are a hole load other things you have to do


but axel stands running in gear at tick over still sounds stupid to me
 
well theres loads of different opinions there. If it says nothing in the book then it doesnt need it. In my new Vespa manual it says keep below 80% of top speed and dont use full throttle. Thats for 600 miles. Ive carefully run in every new car Ive had, maybe contacting Fiat customer service would be helpful.
 
Actually many kit cars are built with new engines in fact most are. My Caterham was a brand new engine. And the engine in my note above was a brand new engine.

The issue was the engine was not under load or very minimal load and you can't run an engine in like that.
 
Come on guys, it's common sense.

Modern manufacturing tolerances & finishes negate the need for a "running in" period as we know it.

Just don't red line it for the 1st 1000miles or so, use varied revs (up to about 4,000rpm max), do not labour the engine.

Just drive fairly sensibly for 1000 or so miles & you will be laughing.

Not forgetting tyres and brakes for the first 100 miles or so, no unecessary hard braking or tyre squealing during the bedding in period.

Whoops, I wouldn't buy the Toyota Yaris I test drove the other week then. 250 miles on the clock, and redlined all the way to 2mph below the book top speed. Ouch.:D (Your only young once)

Of course I'd never be stupid enough to do this in a new car of my own.
 
If you could see your new car being offloaded with 0 miles on the clock at the docks by 17 year olds doing summer jobs you might not worry about being quite so gentle for the first 1000 miles!

I don't know how true this is but when I got my new 156 my Alfa dealer told me to nail it from day one or the ECU will adapt to the running in driving style and it will never perform as fast. Not sure if that was a load of old tosh though....

Exaclty, re the docks thing :eek:

Some cars do have adaptive ecus, I know some of the BMW's adapt to driving style, also auto gearbox settings as well.

Not sure about Fiat 500 though.

How an engine performs in later life will be determined by its running in. Cars that are run in too gently can be prone to burning oil as the rings don't bed properly. An engine which is revved will always feel a bit freer.

As has been said many times, bring it up to temp and drive it......just don't have it bouncing off the rev limiter.
 
My ex demo 156 Alfa 1.9 M-jet goes like stink, even though I do hammer it everywhere, and despite keeping an eye on the oil I've only had to top it up once and that was just before a service when it was still about 2 thirds full.

Could be some truth in the "cane it from the off", being an ex-demo and the "ring bedding in" :eek: theories. :p

the only experience i have with kit cars is a kendal based company my dad used to be managing director for many years ago he still has one today a 2.0 litre vauxhall forenza based morgan lookalike thing by no means a new engine lol

17mph then :devil:
very good

very true

drive a hole bunch of alfas at work and it really shows the ones that are driven by boring people

not nesesarily from new thou if you get a sick one and thrash it some years after new it'll come two so not a permanent fait for the poor things

my dad also currently has a 156 1.8ts and it goes very well with over 110k on the piston rings

So there seems to be many differing opinions on this. But from what I've gathered:

1 It's a bad idea to idle your car till warm...very bad.
2 It's a bad idea to do lots of motorway miles from outset.
3 It's a good idea to cane it around town in order to 'bed the rings'.
4 It's a good idea to explore but not max out the rev range.

Overall, don't be too gentle as this will 'soften' the car and cause problems in later life (kinda like kids who don't get excercise right?)

So now I have a question:

What if I HAVE to do lots of motorway miles from outset (Edinburgh/Glasgow run) do I vary the revs on the road as in 'Kangaroo Petrol'? Cos that don't sound too safe.

Of course all these points and questions might end up moot as the Fiat Manual might say run as normal.

Zakkala what does it say in yours?:D:D:D

Oh my God:eek: have you seen this?...What do they do? I thought they were in containers....Do they cane em around the docks?...we're talking about peoples' property here.
