Hi guys,
Just a quick one... Had my 2002 Hilux 3.0D SR5 Dual Cab for a few weeks now, and have only done about 1200ks.
When we had our last car, we noticed that after about 3-4000ks the motor really started to free up, idled a bit smoother etc etc.
Can I expect a similar thing from the Hilux?

How long till a diesel is "really" run in (the owners manual suggests the usual 1000ks take it easy). I might just be imagining it, but the idle seems a touch on the rough side, as felt through the seats etc.

Thanks for your thoughts.

Cheers, Haggis

Hi, my TD5 Discovery started to really feel run in at about 20000kms. Just remember to keep changing your revs, using the gears etc, so that the engine is "happy" to rev in it's entire range. Also consider running it it at higher revs than you think you will need, as there will be times in the bush that you will need them, and then you'll be happy that the enigine is "used" to them. Hope this helps, Bill Church

Excellent advice winaje a cat warranty engineer said the same thing this way about running in 3 new scrappers and 2 graders work them from the word go how you want them work when run in .The theory is all bearings gears bores etc seat under load and will run truer after they bed down. My 4.2 td patrol freed up around 30000.Keep the service side of up filters/oil .

I've got a TDI Prado. I'd agree about 20-30,000km you'll feel the motor free up.
I've kept a fuel log since day 1 and this reflects the above
