I just got an 08 4runner, will be doing it at 5K as well.
DOne doing the 1K stuff. The only time I will drop break in oil is on my race bikes after a 1-2 hr break in.
I agree with you. I think it is beneficial to keep the factory fill in up to 3,000 or longer. There may well be bnenficial additives in that factory fill so why dump it and turn your back on the benefits? And running it longer then 1,000 will prove no harm, so why not leave it in there?
ALso, the metal shavings/particles which are a product of the break in procedure will get caught in the filter so no worries.
ALso, to pamper/baby a new engine is to potentially cause the rings to glaze the cylinder walls, or not seat well...better to drive the car so that one oscillates between normal and hard, and never keep the RPM's constant for very long.
agree. i only buy trucks with less than 5 miles. Test drive put another 5. Buy truck, warmup drive train for 15 miles. Do some hard runs, not full throttle, but close. Try to use engine decompression to slow down by downshifting.
I sometimes put it 2nd, go hard, and let off. Do it three times, and then drive easy a bit. Gets the rings seated both directions if they were not already.
I will not drive it hard ever, when cold. That was already done before I got it.
