New engine break in and conversion to 5W30
So I got a new engine and of course they put 5W20 in it. I was just wondering how long I should wait to convert to 5W30 like around 500 miles or more or less. I converted my old engine the day I bought it, but should I atleast wait 500 or so miles to let the seals on the rotors set? Also wanted to know what the proper break in for these engines are since I bought mine with alot of miles on it. Should I drive it like I did my old engine (i.e. redlining once a day etc)? Or should I just do normal drinving and shifting for the first 1000 miles?

It didn't have anything to do with the oil it was something wrong with the rotor housings, and it didn't fail they replaced it for pre-cautionary reasons so it would be covered under warranty.

How long will it take you to reach 500 Miles? If you will hit that in less than a month then waiting that long is not a big deal. After a 'new' engine is installed I would like to have the oil & filter changed within 2 weeks.

Ok thanks! Also I know alot of people use castrol on here but is pennzoil 5W30 also a good oil to use. I know they are all about the same but just wanted to get some thought on that. Also whats the best way to break in the new engine? Should I go easy on it or should I drive it like I normally would?

The tips on http://www.racingbeat.com/FRmazda4.htm are about as good as anything I can think of. Castrol is a fine oil to use. I personally use Royal Purple 5w30 Synthetic. I will be switching to 10w40 RP once my supply is gone.

I used pennzoil once when i first got it seemed to work fine it's all basically personal preference now I use Castrol 5w30 but have used Valvoline also and like both of those.....
and for breaking it in alot of ppl have different opionoins on breaking it in but I say that you need to take it easy....do not redline and don't stay at a constant RPM for a long period of time do this for about 2kmiles and then let her rip you're good to go

My RX-8 have been filled with 5w30 since it was new in 2004, but my compression failed anyhow. So wouldnt worry to much about when to change over.
5w30 is standard on the Norwegian version of this car.

You don't need to sign up for it. You should have gotten letters from Mazda explaining the extended warrantees, along with pages to add to your manual, but it applies automatically. If what you threw away said you needed to sign up, it would have been junk mail from a third party warranty con outfit.

Engine internal parts are guaranteed for 8 years, 100,000 miles. Driveline 5 years, 60,000 miles. Bumper-to-bumper 4 years, 50,000 (or is it 48,000?).
