Running in a new engine

You can find a random website supporting any thesis on the internet. If you looked for a break in method which involved running from day 1 and never doing any oil change at all there would be a website somewhere...

See my post at 8.37 this morning

Ok, since I posted this theres been mention of using mineral oil and changing it after a thousand miles.
When I picked the car up from being rebuilt I was told run in for a thousand miles then drive normally until the next oil change at approx 6000 miles. It currently has fully synthetic 5 40 in it ( and Im now up to 700 miles). Persom
Personally I thought it would have had mineral oil and a sooner change?

Ideally if the rings have been replaced a mineral oil should be used for the first part of the break in process. Nobody bothers with that these days though.

I would accept that it's a bog standard wheezy 1.6 four-pot run of the mill mass produced engine and actually it makes absolutely naff all difference how it's run in.

How do you know it’s a ”bog standard wheezy 1.6 four-pot”? It could be a Lotus Elise for all you know.

38911 funny though it is, that doesn't make you any less wrong

Some nice selective quoting from you there. You edited out the 'Sport' which means high lift cams, lightened flywheel etc.

So not a bog standard wheezy four pot after all. Well done on showing yourself up as even more wrong

It really is you know, just with a little added oomph!

Actually I used to drive them off the ships at the docks for summer work so I know exactly how they get treated. But mine arrived with 4 miles on the clock so the piston rings still had plenty of time to bed in.

They can zero the odometer at PDI.

I was shown our new car when I went in a few days before to sign the finance documents. The valeters where working on a bunch of cars all sitting there with engines idling (supposedly the worst thing you can do to an engine) and radios blaring.

Err no, adding capacity just adds oomph. Tuning an engine totally changes the character of it too.

Would have thought you'd know better with a name like 750turbo

Must. Resist.

Yeah, in exactly the same way that an M135i has a wheezy old 6 pot, just with a bit more oomph.

Warm it up properly (as you would any engine) and then give it hell.

Unless you own the car. Then go a bit easier on it.

Actually this, you need to force the rings into the bore to bed in properly, have a read of the mototune method of running an engine in, done all my bike rebuilds this way.

I agree with this guy .. the 1st 60 miles are critical. Find some hills and give it some load to push against.

A well run in engine will use less oil and produce better bhp.

Erm... I was backing you on the importance of break in but let's not get silly now, the 1.6 engine in the Swift Sport is just as mass produced as any other mass produced engine, and 85bhp / litre doth not an exotic race engine make.

As such the break-in procedure will be the same as any other mass produced engine, wheezy or otherwise.

Huh yourself, I'm just pointing out the flaw in your argument.

If you believe a higher performance 4 cylinder engine variant is just a wheezy old four pot with more oomph, then the same must surely apply to all other types of engine? There were plenty of wheezy 6 cylinder engines made in the past, so modern ones are just wheezy old six pots with loads more power.

Sorry if this has already been mentioned, but I watched Shmee's video on Youtube of his Cayman GT4 collection, and the dealer told him directly that it had no run-in period, and he could go hard straight away.

I spent 10 years working in Dagenham engine plant for Ford.

Every engine went into a dyno cell at the end of the assembly line. Each engine was hot tested for approx 15 mins. This included a warm up and break in cycle, load testing and a cool down cycle. This was not done on the car production line, but the engine manufacturing line

That is not a "break in" test, it's a basic functional test and ensures there are no oil leaks etc. and I would expect most manufacturers do something like this. A new engine can not be broken in with 15 minutes use.

True, but in the past the main reason for a break in was to ensure that all small metal flakes and bore irregularities were removed. Hence the use of special oils with quick oil changes. These days the manufacturing is so much better than you dont need to have such an importance on breaking the engine in, so some manufactures just do a first oil change at 10,000 miles or whatever. Just drive it normally from day 1 and you wont have any problems.

It must have been a few years ago... I visited the new diesel line (the one that makes the smaller diesels) at Dagenham in 2007, some engines are hot tested, some are cold tested (i.e. turned by a motor but they don't fire themselves). Completely agree on the point about a hot test being quality control, not bed-in!

[rigga]

Watched a dream car program the other night, mclaren something or other, can't tell them apart myself, anyway each engine was dyno tested after install, revved pretty much throughout the rev range and pretty well loaded, any thoughts of carrying out any run in procedure after this is a moot point, as most of it had been done already, no one buys a car without it ever being run before by someone else unless you personally build the engine yourself, and then can be certain how it's broken in, your worrying about nothing, you probably have no influence whatsoever on how it will perform in the future.

I keep reading that the magicical mark where all is good is 1000 miles, does that mean in countries where KM are used they have to wait until 1600 km's.

It's all bks, just drive them.

Now you're embarrassing yourself.

It's a budget brand, mass produced engine with just 134 BHP. It's not even remotely high performance by any stretch of the deluded imagination.

You're banging on like its something special.... It's not! My 78 year old mother in law's diesel runaround has more BHP than that!!!

"Sport" indeed

So you think 134bhp from an n/a 1.6 is "bog standard"? As is the lightened flywheel?

It's not the total power the engine produces that is what performance is judged by, it's the power per litre of the engine and power to weight of the car. Both of which are a fair bit higher than an average or "bog standard" car. So who cares how much power your Mummy in law's car's got, she might have 250bhp but if it's in a 3 ton car it's wasted. Whatever it is it's still shown up by the output of an artic lorry. Why don't you upgrade her to one of those for Xmas..

As usual you're totally missing the point. Your argument is that this car is so average that who cares if it's not run in properly. What a pathetic waste of space you really are. It's my thread and it's important to me just as the subject is to the other good contributers of this thread.

So if you think it's not important then f**k off and contribute to another thread you think is.

What an idiot..
