View Full Version : Running In New Car

Done the search, no luck.
Do we need to run in the D4 from new?
Getting mixed responses, some say new cars are already run in, others say first 10,000ks are critical for life of engine, fuel economy etc. a mate of mine who is a diesel mechanic says you should run then in, by making them "pull" so using low down torque rather than revs/power for the first couple of thousand.
If so what s the best running in method? Drive it like you stole it? Drive it like my nan?
Thoughts....

Basically the engine is already run in - so drive it "normally" or as a normal person would do.

Ditto.
City driving is probably the best way to run in an engine and driveline as it forces you to go up and down the rev range without getting things too hot (initially).
Constant speeds/constant revs is the second worst way to do it, (eg. freeway driving) and by far the worst way is the old fashioned pussy footing around with minimal revs/load.

Does this mean I shouldn't head down south on the freeway to a mate and fellow Landie buff straight off the forecourt at Southern Landrover on 20 November?

Just don't sit on a constant 110km/h, go up and down in speed a bit and, while no one bothers, crown wheels and pinions really do need running in and like a few cool off periods in the first few hours of operation.
New race car diffs are always run in needing quite a few cool off periods, and drivers hate doing it.

Thanks Rick
 
It's only about 100k South of Perth so I'll vary the speed and it will only be an hour before it gets a rest.
 
Varying the speed will not be a problem because it'll be peak hour coming out of Perth and some WA drivers love to sit in the middle lane and block traffic for a while before the cars behnind them can undertake.

Get it properly warm and go for a drive through the hills with the whole family on board. That way you vary the revs and there is always a load on it. Do not be scared to give it a bit of welly as well.
This way the rings are being loaded up and bedding in which will determine your future oil consumption. If you pussy foot around the bore will glaze and later there will be oil consumption problems.
To sum up; all it takes is sensible driving and making a warm engine work within its design parameters, meanwhile for the driver you will have a very silly grin with the sheer pleasure this will be giving you.

Hey Jaybee75, 
All good advice. My father in law is a diesel engineer & mechanic. 
His advice to me is.... Letting it labour won't hurt it, vary your speed & don't over rev it. 
Pretty much what everyone has mentioned. 
Most of all..... Enjoy. 
Cheers, Craig

You should always give it a good lead foot once in a while. Soot build up in your egr valves can cause them to stick open and cause bad problems. Plus it clears all the soot out of your exhaust system and just gives everything a good wake up.
It's also fun.

Just as a matter of interest what sort of de-sooting regime are you talking about and for how long? Would smoking it up at the lights on the odd occasion you're along side a Prado be enough or are you talking as 10+ kilometers of sustained fang once a month?
 
Perhaps D4/RRS owners in each State can meet regularly for some desooting drags late at night somewhere in the country.:cool:
 
It's a pity when various things go wrong the car goes into limp mode yet when the EGR starts to get blocked it you don't  get a message like "EGR valves Error. Commence Rocket Mode in 4 seconds. Please hang on."

Maybe take the old coastal road, via Mandurah and you're speed will vary enough.

That would be fun,but an easier way is wait until one of those tojo/nissan things pulls up at the lights next to you,then hold it flat for a while after the green is on:)
The only thing i wouldn't do is tow for the first 1000k's or so.
Also don't stand on the brakes too hard for a while if possible.
I have just driven them sensibly when new( for the first 2000k's or so) & never had a vehicle use oil or had any other engine issue ever.

Haha I like your thinking, it would be pretty funny to see.
Just if you've driven the car like a nana for a couple of days, give it a good boot till you can't see much black smoke, diesels will always be a little bit smokey.
If I get a car that is blowing excessive black smoke at work, we usually spank it round for about 5 minutes and usually they are cleared, sometimes they don't and then the diagnosis work begins -.-

This bloke has very strong feelings on the subject.
Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power (http://www.mototuneusa.com/break_in_secrets.htm)
This site recommends a slightly different approach.
Running in a new car | The AA (http://www.theaa.com/motoring_advice/general-advice/running-in-a-new-car.html)
This site explains why the first approach might not be appropriate for a diesel.

Good way to desoot is to go for a drive in soft sand. Although, even then the 3l is not working all that hard.

I have found the best way to desoot the D3 is hitch the caravan up and drive for several hours with the welly stuck into it. Especially up through the hills.
Then Unhitch the van and the bloody thing takes off like a raped ape! ...:eek:
cheers,
Terry :)
