Run a non-synthetic oil. Drive normally for 500-1,000 KMs. Change oil soon after the first drive, maybe within the first 100-500 KMs. Ask a good mechanic mate but opinions will always vary.

Drive it normally shifiting below vtec around 3-4k revs. Check in with your mechanic after 1000km and see how its doing.
Pretty sure he will have all the answers. If he doesnt get a better mechanic lol

I don't know how true this is, but here's an interesting read.

It's all true & it works...

Or if built with cams etc & the tune is out the window.
Get it to stoich asap & get on with tuning it on the dyno.
1st oil & filter change is critical - within 1st hr of operation.
Don't **** that up.
Once tuned, she's run in.
Change the oil again & do your worst.
Pissing around with long km run in period is just b/s from people who don't really know.
Run it in hard & it will last a lot longer, make more power & use no oil.
The reverse is true for engines that are babied.
How the pistons & rings were installed also makes a difference.

so what about when you get the car brand new and they tell you to baby it for 1000k's? Conspiracy?

I don't think anyone takes their brand new car home and changes the oil?

**mugen_ctr** · 30-12-2011 11:33 AM

What about running and breaking the engine on the on a dyno? i know many tuners and race teams do it, but would it be worth the dosh if any one with a rebuilt motor does it? or waste of money an jus do the old fashion on the road lol

Most manufacturers are a step ahead anyway with new cars,
The car comes off the production liine & straight on to a rolling road where it is run in.
Takes about 20 minutes, they just drive a program, checking temps etc along the way.
Oil & filter are then changed the its off for delivery.
Ferrari even track test each car before delivery.
The 1000km conspirators are pretty much just the salesmen who really have no idea in the 1st place.
Watch Megafactories on discovery & see for yourself.

Yes, its worth it.
The engine lasts longer, uses less fuel, makes more power, is quieter & doesnt use oil.
The "old fashioned way" is not the best way.
