Which oil next? Mazda skyactiv 2.5

Exactly....basically every 6th oil change free~~
 
Do the 6qt boxes have quart markings on them? I have the oil changed at the dealer bc it's only $25 including filter if I bring my own oil, plus free wash/vacuum and inspection. Oil change with filter is exactly 5 quarts so the jugs are awfully convenient

At this point leaning towards M1 0w20 EP with 7.5k interval for the next change. After doing some reading it seems that 0w20 EP contains a majority PAO base, which if I'm not mistaken, means more resistant to shear & oxidation than a Grp 3.

Unless of course there's something special about the Motul 8100 eco lite 0w20...can't seem to find much info on it

If you can't find much on it what so special about it the price tag? Cheapest I've see it is $32 and change and its goes up to $42 from there.
 
As PimTac says they are marked.

I have a 16 cx5 and 18 Mazda3 both with 2.5 skyactiv motors. Both are using QSUD 0w20. Cheap and readily available at Walmart. When I changed the 3 from its factory fill there was a noticeable reduction in engine noise which I (personally) found satisfying.

you refer to the new car one?
 
"19 cx5 awd with 2.5L skyactiv-G and cylinder deactivation. About 3-3.5k miles per month with about 80% of that being pretty mellow rural & freeway driving. Here's what I've run so far:

0-2k miles - factory fill

2k-5k miles - Mazda 0w20 syn (not high moly) - car ran great, good mpg

5k-10k miles - Idemitsu Zepro 0w20 high moly - engine ran noticeably smoother/quieter at idle to the point that I forgot to shut the engine off a couple times in the driveway. Good mpg, perhaps slightly better than previous but could be attributed to engine breaking in

10k-current 12k miles - Castrol Edge 0w20 black bottle - engine runs well and mpg is similar, but idle seems a touch rougher than with the high moly Zepro

So what oil do you guys think I should try next at 15k? I realize that pretty much any d1g2 0w20 should be fine, but that would be too easy and mean that I'd actually have to focus on my work instead of screwing around online. These are the options I'm currently considering:


M1 0w16 for 5k interval - would the thinner oil help mpg? Or stupid bc could potentially hurt warranty. Read this has higher PAO, which can't be bad

M1 0w20 EP for 7.5k interval - oil change every 6 weeks is getting old, also supposed to be majority pao correct?

Edge titanium gold bottle 0w20 for 7.5k - with the recent talk of titanium and potential for longer OCI, another seemingly good option

Shell gas truck 0w20 for 5k - newer formulation with more moly than most

Idemitsu Zepro 0w20 d1g2 for 5k - a bit pricier than others at $30/jug, but still reasonable unlike Zepro high moly that has jumped to $40/jug. VOA showed high moly numbers and appears to be on the thinner side of 20wt...

QSUD 0w20 for 5k - cheap, seems to be well liked here, has some moly

Motul 8100 eco-lite 0w20 d1g2 for 5k - is this an ester based oil? If so might go this route at the price (about $6.50 per liter)


Okay well I'd better get back to work. Opinions welcome...
JMO the 0-16 is too thin. Try M1 AFE 0-20 it's an 8.8 vis or Pennzoil Ultra Platinum also an 8.8 vis. Walmart delivers to your door on orders over $35.
 
in southeast asia: 5w30 dealership ~$40 oil change for a 2021 mazda cx5.
