what is the normal break in for a new mazda reman? i have heard 600 to 1000, im sitting at 700 something a getting itchy....

 

I was told below 4k rpm for 500mi. Then each 150mi past that you can go 1k rpm more.
That's what I'll be doing.

 

I broke my reman 13b engine with dyno oil changes at 250, 500, 1000, 1500 and 2000 mile intervals. Kept engine under 4 K rpms, no boosting (even though its tough to do). Also added AMS cycle oil gasoline mix to give extra lube during breakin.

In addition, I attached a magetic core around the oil filter to trap any metal shavings produced during breakin period.

At 2000 miles, I used AMS oil flush and switched to Mobile 1 synethic oil.

 

I have 230 miles on it. I had to reseal the pan so I squeezed an xtra oil change in there...thats 2 and today's makes 3. I have the rev. limiter set at 4400.
Im bringing that up to 5k drive it close to 1k, change oil and tune it!

 

After all that love'n care you put into your car you put synethic oil into it??????? what are you thinking?

 

0 to 500 miles, shift at 4k and minimal boost. Change oil.
500 to 1500 miles, shift at 5 to 6k, minimal boost. Change oil. Tune.


And after my break-in I'll be switching to synthetic too.

 

Not here to start another debate but, make it three. The lubricating properties of synthetic oil are superior to dino oil. Just make sure the apex seals have lapped in to match the rotor housings before changing from dino to synthetic. I believe using synthetic along with premix in the gas keeps the engine cleaner internally. Also, synthetic oil does not turn corrosive over time with the introduction of carbon and gasoline.

Yeah, this dino vs synthetic engine oil debate has a long history. I have decided to switch because of my personal observation of the carbon build up in the turbos when using dino oil.

I replaced my twin turbos after using dino oil and found that the turbos had a build up of carbon deposits. Then I installed a different set of turbos, ran synthetic oil for about 6,000 miles before the coolant seals blew.

Ported out the wastegate and found that the turbos were actually free of carbon deposits before installing into reman engine. That is why I switched to synthetic, wanted to keep those turbos clean. Also noticed it ran a bit cooler.

 

This is what I recommend for all our customers, with the exception of 5-7 psi boost for the 500 to 1500 mile interval.

This has been posted about 75 million times before, btw

 

so rich you also recommend switching to synthetic once broken in too? lol

 

^^Definitely. Always have.

 

IIRC, I got it from you or Ihor during a search of one of those 75 million threads. I probably should have credited you guys. Sorry.

 

you ran it with the bnr's too? i tho it said not to use synthetic
