For the car i am looking at using mobil 0w 20. The car is a year old and has 11k miles. My wife works from home. This is about 1/2 short trips and half from trips ranging from 200 to 500 miles each way. We are in the midwest so gets plenty cold in the winter but the car is in a semi heated garage.

For filter i am thinking of a royal purple. Oil change interval of 5-6k. For a DI engine i like the better filter and not going to extended intervals. The ro filter is about the same cost as the mobil 1. It is maybe 6$6 more than a mid level filter. The added cost is about $12 a year.

You can run those engines well into 6 figures using the cheapest oil & filters on the shelf that meet the specs.
Nothing wrong with paying a little more if it provides peace of mind, if nothing else as the engine doesn't care.

Nothing wrong with the Roki filter and you can get them for around $8.xx. The M1 filters are about $12 at Wally’s. Not sure what the purple filter runs.

Mobil is a good choice. You can run any major 0w-20 with no worries.

After reading more on the CX-5 in the EU as well as Mexico they are all Spec for 5W-30. In fact my owners manual mention 5W-30 as well as 10W 30. So far I'm short of 1000 miles and the dipstick is still showing full.

Not to threadjack , but a new Mazda CX5 would be on my short list to buy ! My son has a CX3 and I love driving it (I just need the larger CX5) . I always change his oil and used M1 0W20 EP with a Fram Ultra filter with an OCI of 6,000 miles . So far , the CX3 just runs and runs . If I bought the CX5 I would use the same M1 0W20 EP .

I have a 21 cx5 at the house. I use Mazda oil filters (no anti drain valve - no need and they’re high quality) and it’s been on kirkland 0w-20 since the second change. Got a bunch of Valvoline extended protection with the rebate offered. Will be moved to that in a couple of weeks. Great vehicle.

Here is my reasoning on your filter choice. The Skyactiv uses a 2 step PSI pump. The filter switches 1/2 to full PSI and is controlled by many inputs to car computer. (PCM)
The OEM filter is designed for the Skyactiv. When the Skyactiv engine came out there was a Mazda bulletin came out not to use the previous filter but to use the new part number filter.
Some more info…

My 2019 MX-5 filter choice is the made in Thailand one.

I was very Leary of the the cylinder deactivation but so far its working out well. No long trips yet but so far my combined MPG is running around 27.2.

Is yours a turbo? They do call for a 5w30. The no. Turbo is 0w20

Mazda punches so far above it’s weight. I’m a LONG TIME Honda/Acura person and I love the one my gf has.

If the current CX-5 still was offered with a real transmission there would be two of them here in the driveway to keep some miles off my Type-R.

I only feed it Mazda OEM filters, all three (oil, air & cabin). Extremely high quality parts and worth the money. I’m not typically an OEM parts person either. Mazda does things different enough to warrant it.

We hit 30+mpg easy on ours out on the highway at 75mph. I run it 7500 between changes since she drives 3x a week to the office 70 miles away.

You mean a real transmission as in the SkyActiv manual drive? The automatic is a pretty good transmission on its own. It is pretty much direct drive 95% of the time.

I get over 30mpg regularly. I’m close to that in the winter but will get around 32 as summer blend gets in the tank which should be around now.

Yeah I’m nowhere near ready to give up a clutch pedal. The 6sp auto is pretty good in it though and makes it tolerable. Lightyears better than any cvt on the market.

The 2013 CX-5 in my signature is a stick and fun to row through. The variable oil pressure is controlled by a solenoid on the back of the engine. It simply bypasses some oil back to the sump thereby reducing the force needed to pump the oil. I replaced it on the 2013 looking for a leak that turned out to be the output seal on the front axle. It's not a complicated system and other markets are spec'd for 5w30 for the same engine so you don't need to panic about other oil weights.
