I recently purchased a 2012 MazdaSpeed 3. It, of course, has a turbocharged 2.3L I-4 motor. I drive the car as my commuter and travel vehicle. I do NOT race or autocross. Other than the occassional sprint past 100+ mph or highway merging, the engine will see mostly light duty.

I have used Mobil 1 full-synthetic (in whatever weight the manufacturer called for) in every car I've owned for the past 10 years and never had a problem. In fact, I've been nothing but impressed with Mobil 1.

However, I'm still open to using a better product. Do any of you have a recommendation for something that may work better than the Mobil 1 for this motor (keeping in mind that it has a turbocharger)? The manufacturer calls for 5w30 to be used. Would any of you go to a higher viscosity? Or just keep it the same? Any other tips are also welcome. This is my first turbocharged motor.

I have one more question: does anyone know what they put in the Speed3 from the dealer? My car only has 500 miles on it (thinking about doing the first oil change at 1000 miles).

Thanks in advance, ya'll. Cheers.
 
Welcome to BITOG!

Yes Mobil 1 5w30 would be a good choice and it would be unnecessary and unadvisable to use anything heavier.

I don't know what the factory fill is other than it likely being a 5w30 synthetic. The dealer for service fill I believe uses a Conoco Phillips made product.
 
With a turbo, I'd stick to full synthetics.
M1 is great, but there is no magic in there.
Anybody's will be fine. [in the right viscosity]
 
My vote is for Mobil 1 5w30. It has Honda's HTO-06 approval for turbocharged engines, so it will work fine in your engine.

A 2:3 mix would be better as it will match the HTHSV of Mobil 1 5w30; there's no need to go heavier.
But really lets keep the esoteric stuff for the truly die-hard oil geeks; the Mobil 1 5w30 will be fine or any other 5w30 that meets the Honda HTO-06 high temp' spec'.
 
To the OP:

Read your second paragraph.

Cheers!

p.s. Seriously, the only possible suggestion I might make is to try AMSOIL's ASL 5w30, especially if you want to investigate longer OCI's after the warranty period expires.

Yea, M1 is fine.

I'd put in Amsoil ASL 5w30 though like my friend does in his MazdaSpeed. Plus, it has a nicer shot of Moly in it.

Redline would also be fantastic.

Stick with a group 4 or 5 for sure as that engine is hard on oil.

Let's see if I've GOT THIS STRAIGHT:
"hard on" is OK (for oil): a "hard-on" for oil is not?

Cheers!
 
You can always go with Mobil 1 High Mileage 5w30. It`s got a stronger add pack over their regular 5W30.

Not recommended since HM is only an SL oil, doesn't meet warranty requirements, doesn't meet HTO-06 spec' and has a lower VI.

Well done.

This is one of the few times I have seen on BITOG you first give the answer and then ask the questions.

IMO these answer is
"I've owned for the past 10 years and never had a problem. In fact, I've been nothing but impressed with Mobil 1."
 
Just stick with the Mobil 1 5w30 you know and like!

With a turbo like this though, I would stick to right on-time oil changes unless you do used oil analysis after break-in and warranty and determine it can be pushed.
 
Thank you all for the great responses.

I decided to go with Mobil 1 5w30 (not HM) and a K&N oil filter (HP-1002).

Interestingly enough, I owned a 2008 Toyota 4Runner (4.7L V8) before this car...and in it I used the exact same oil filter down to the model number.
 
My 2008 MS3 has also seen pretty light duty (only 22,000 in nearly four years). Occasional redline, all city, lots of short trips. My OC history is:

#1: 1250 miles, then every 3000 miles thru 18,800. These changes were all Pennzoil conventional. Switched to PP. Dropped the first syn fill at 3350 because it looked, felt, smelled shot (waiting for UOA results). Engine looks clean, blows no smoke, burns no oil. Based on what I've seen so far, I seriously doubt that the OCI can be extended much with synthetic. I wouldn't hesitate to use M1 in my car and in fact, have several OCs worth waiting on the shelf.

A blast to drive this car. The OE Potenza RE050s are wonderful as are the Blizzak LMs in winter. If only it were RWD...

Two mods I would do again: TWM short shift kit--easy DIY, be sure to get the metal bushings. cp-e CAI- don't settle for a lesser brand and be sure to get the filter sock! Love the sound and cheap power boost.

Thanks for the post. Already ahead of you: I save ALL receipts for oil (and filter) and log mileage at changes.
