Mazda CX5 2.5 oil question

[Tallman]

Vehicle is a 2014 Mazda CX5 2.5L with 98,000 km. The maintenance logbook shows all services have been done at around 10,000 km or less.

A quick check on the internet suggest the suggested oil for our 2014 Mazda CX5 2.5L on a number of websites is a 0W-20. The handbook suggests we can use a range of oils from 0W-20 to 10W-50 depending on oil temps. Our local temperature range is -10deg C (14 deg F) to 45 deg C (115F)

In that basis, the manual says we can use either a 10W-50 or maybe a 5W-40 or 10W-40. Options on the oil I should use?

Our Mazda 5 with the 2.5 gets 0-20W all year long runs great, Uses no oil between 5000 mile changes. I use Synthetic in it. Yesterday was hottest day of the year here at 97 F.

My 6 with the same powertrain was happy on 5w-30 year-round.

I used M1 AFE 0w20 in our Mazda 5 for the first 100k miles without issue, but then again our local temps are a bit milder than yours. Perhaps consider AFE in a 0w30 weight if you're concerned about the higher ambient temps.

I use 5w30. On 5w 30 or 0w20 my car uses 1 quart per 3000 miles

Guys, Guys,
The OP is in AUS as In Australia!!!

No chance of him getting 0w20 (unless he buys on internet and pays customs taxes...).

I would recommend go with the 5W-40 or 10W-40 available locally, either synthetic blend or synthetic.
Leave it for 6kmiles/10K kilometers. I think the Mazda branded filters are pretty good.
Just check your oil level every other fill-up.

Also, I think these cars like to be driven. So maybe a really early Sunday morning 2 hours run once a month on a the highways? Twisty roads are even better.

At 98k kilometers I would check the AT fluid and maybe do some some drain-and-refill to gently refresh.

Personal experience: I cannot say much since my Mazda5 uses a NA 2.4L engine with NOT the skyaktiv technology.

If the car has been running on 0w20 all along then stick with it. Your cooling system takes care of the heat. Make sure that has been maintained as well.

I would use a synthetic 5w30 with your temperatures. Ed

"Our local temperature range is -10deg C (14 deg F) to 45 deg C (115F)"

I would use either a 0w30 or 5w30 for your climate.

-10 ?! where are you, Snowy Mountains and does it get as high as 45 up there? With that big of a swing I'd use 0W40 synthetic.

 

[CT8]

5w-30 or 0w-30

 

[donnyj08]

If you have a 5w30 or 0w40 available down under I'd use that.

And A5/B5 5w30 would be a good fit IMO.

 

[ka9mnx]

5w-30 synthetic...

 

[VQ35DE]

Mobil 1 AP 0W-20 for me.

to this madhouse.

In your climate I would go ahead and use a 5w-40 or 5w-30 year 'round.

Havoline 5w-30 or 0W-20 Econo box 6 quarts for $19.97 should serve you well

 

[Matt_Pill]

We have a Mazda 5, not the same as your racehorse but have been using 5w-40 since it exited warranty.

 

[hpb]

I'd use 5w30, probably Castrol Edge, in fact I think Supercheap have it on sale for $35 at the moment.

 

[SR5]

Hi Mate,
I would use a full synthetic 5W30 such as Castrol Edge, Castrol Magnatec or Shell Helix HX8 they are all 5W30 A3/B4 rated oils and fairly easy to find at reasonable prices if you follow the sales at Repco or SCA.

Also Valvoline make two SynPower 5W30 oils, the FE which is A5/B5 & Ford 913-D, or the DX1 which is Dexos1-Gen2 & GF-5. Both of these are thinner 5W30 oils but also quality full synthetics.

 

[RayCJ]

In your cooler season, use 0w20 and in the warm season, use 5w30. Either of these types of oils will be fine in any climate. Doing seasonal changes this way gives you the best of both worlds. No harm done if your oil change doesn't happen exactly when the seasons change. The Mazda 2.5L is a very good engine that is not oil finicky. I have the same engine. You will get reduced economy if you get into the 40 or 50 weight oils. 10km intervals is fine for most driving conditions with that engine. Use any modern name brand or no-name oil as long as it is properly certified.
