2011 Navara st D40 engine run in procedure??

[TONY'S D40 st]

hey guys im new to this forum and i was in the process of buying a black 2011 Navara D40 ST manual transmission brand new and should be recieving it in the next few days. I was just after some helpfull tips and info on what is the best way to run the motor in and for how many kilometers should it be done for? Is it also not recommended to tow with initially until some klm's have been put on the clock?? Cheers guys

just drive it like normal but without over revving so try to keep it under 3000rpms, you shouldnt need to rev it harder than that, dont tow and seriously heavy load like a caravan or something but a normal trailer would be fine, try to let the motor labour a little bit to bed in the rings and try not to keep the revs constant like on a hwy or something. first thousand kms i would do this then drive it like its under warrantee

BTW welcome to the forum

Thanks for the reply ONLOCk, sounds good ill give it a go

Welcome too the forum and have fun, Onlock is right on the money. you only really have too take it easy for the first 1000km then get the 1000k service done, this will remove any exccess metal from the bedding in.

Welcome aboard.

As above. The engine will still be tight for a good 10,000km or more. Your fuel consumption will remain a little higher than expected until the 10,000km service, because the vehicle is shipped with a richer fuel map to reduce the engine temperatures while it's still new.

Ok, that's interesting with the engine having a richer fuel map. Always been my understanding that in a diesel engine, richer = hotter exhaust temperatures. As opposed to a petrol engine where richer will help keep temperatures lower and leaner, hotter.
Maybe there shipped with a richer fuel map to aid upper cylinder lubrication rather than reduce temperatures?

Possibly. They're definitely using more fuel when they're young (before an ECU reset anyway). You can get rid of this by resetting the ECU yourself - but I wouldn't do that. I reset mine @ 13,000km and the fuel consumption dropped by around 2LPHK - maybe slightly more, it's hard to tell, because I was doing a lot of mixed towing/not towing over that period, but the trend before was for around 13-14LPHK around town, and 11-12LPHK after the reset.

I too am expecting a black D40 in the next week or so - if mine turns out to be a lemon I'll swap ya!!

My Fuel consumption didn't change. It was good from the first tank.

Personally I just get in and drive them like any other day.

With my petrol engined cars, I actutually hook up a trailer with a old queen matteress on top and run the first 1000kms dragging that around.
