oil for MP3

well .. generally royal purple is just a name. but i mean its really just like any other oil. i would recommend 5 w 30 though. but ive seen plenty of mazda motors run better on dyno oil. i guess it just depends what the car was run on its whole life. but regardless change it every 3k always. if you decide to go turbo in the future however change it every 1200k turbo;s tend to find oil tasty. :)

Royal Purple is really good stuff. My guess you got some good advice and started putting that in.

The consensus for any car is synthetic. It really is a much better oil for almost any car.

As for type, it depends on location and climate.

I run 5w-30 in my MP3, synthetic Mobil One High Mileage, I have around 76k miles and I burn oil, so I've been trying the High Mileage to help prevent that.

I run 10w-30 in my truck because of the cold weather up here, and even more extreme on the mountains where I go snowmobiling.
 
Im putting in a hole new motor so I just want to start it off with the best. I live in utah where it it getting pretty cold already, but i think i will stick with the royal purple and do the 5w 30. thnx for all the input!

Why do you put 5w in the pro, but 10w in your truck? I would think you'd want the lowest winter weight possible if that's the one you've got out in the elements.

WHoops, I got it backwards in my post, 10w in the MP3 during summer. 5w for the truck and even in the MP3 during the winter.

Sorry for the confusion! (dark)
 
Amsoil blows by the piston rings, causes black smoke, fouls the cats and O2 sensors...

I recomend changing...
 
Mobil 1 5w-30 in my ES with 52k miles. And I've been using that since I bought it with just less than 30k miles. I know Mobil 1 5w-30 isn't a "true" synthetic anymore, but it's good enough for me. Plus 5 qt jugs at Wal-Mart are about $21.

My 1991 626's engine was still running strong at 197k miles with dyno oil and Slick50 when I got rid of it. The transmission, however, was limping along. I don't necessarily recommend Slick50, but it didn't hurt my car during all those miles- and my dad bought it brand new and put Slick50 in shortly after buying it.
 
I run Royal Purple 5w-30 year round. 5w is lighter making it easier on the engine. 5w-30 is recomended for any 4 cylinder. Synthetic is obviously the way to go though.
 
5W30 is great... Honestly though if you get stuck in traffic on hot days often with the AC on I would switch to 10w30 in the spring to fall
 
I know the engines aren't the same, but we have a truck at work with over 350,000 miles on the original engine. Motor oil is important, but the type isn't nearly as important as CLEAN oil.

Honestly though, Redline motoroil is kinda like liquid horsepower.
 
You guys ever watch horse power TV? they have a new engine dyno, so they tried it out, ran with regular oil, then switched to Royal Purple, same engine, same parts, same temps and everything, it made a extra 8 hp and 7fp-tq. I also see trucks do the same thing, the truck made a extra 3wph and 2 fp-tq (at the wheels).

I've never heard of redline, but I assume it's much the same.

Huh? Why? When the motor gets hot, the oil goes from acting like 5w oil to 30w oil. So switching to 10w30 would do nothing for hot days.

5w30 year round FTW.

And yes, Red Line is similar to Royal Purple.
 
Redline is superior to Royal Purple IMO, as I have used both. I've been using Redline since 2003, and we all know the "abuse" my car has taken. I use 10W40.
