First I apologize if this was asked before. Couldnt find much useful information out there and it seems like everyone has a different method when talking about the rpm and mileage and when to do the first oil change. So I want to see what you guys think and what you guys did when you bought the car. Maybe we can all compare what we did and get a consistent break in method

My case...

So my car just got a new engine today covered under warranty due to a coolant leak. I was talking to the rotary tech and asked him about how to break in the engine properly and he said to stay below 4000RPM for 8000kms so like 5000 miles ( fml ). Is this correct? what are the thoughts from people who experienced this before or from people who bought the car new not that long ago and remember?

Thanks again

500 miles, not 5000

Break it in hard, and fast. The most important part is the very first start up. If you run it hard, everything seats better, and you will have more power in comparison to people that baby it forever before running it hard.

the debate begins...
george, I'd say read on what people have said in the past, then come to a conclusion

yeah thats what i thought too but then i remembered that thats how it is for piston engines so i wasnt sure about the rotary..

rx8soldier..your so right! this will turn into to another debate! i actually used the link in your sig that i got from another thread to do some research and honestly it looks like half people say to go hard on the car and half people say the oppossite. What would you do in this case?

I can't believe this is still an "argument". Technology in fluids, seals and metals are much better than they were 30 years ago and do not require the babying. Beodude is 100% correct.

warm it up, run the rpm a little bit more closer to the red line everytime. start 4000, then 5000 then 6000, goes on. until 9000 then go back down.
its like prepare for singing, you increase gradually, you dont scream or not make sound at all.

OP- This is the only advice that you should take seriously from this discussion.

There are some very good points from that article from Racing beat though. I've read that not full throttle is better. Maybe gives things more time to settle? No hard starts nor stops also.

Granted, all I've read about is from piston engines, so it could differ slightly, but from what I've seen on Mazda 6's, and other platforms, engines run in hard seem to have higher HP than other cars.

Anecdotal, yes. Science? Maybe.

not for rotary engine.

we have bearings that needs a lot of love ... lube I mean, if you run it too hard when the oil are still "cold" it will kill those bearings,

the rotors will be more "off" balance, which results in more bearing wear, which results in even more off balance ... u get the idea.

the more cold start + ultra high rpm rev the faster Rotary engine dies.




and for the Racing Beat page. I do not agree to the 7500 miles oil change thing, especially if u want me to use 5w20 junk.

you do realize that you're not supposed to break in any engine when the oil is still cold right?
