hard question to answer as there is no real comparison or control for such an experiment. at least nothing i've seen so far.Has anyone noticed a reduction in carbon on the intake valves using a particular brand of oil? Skactiv seem to do well on just about any brand.
I have been running liqui moly 5w-30 Molygen after i got to 200K kms (2012 2.0L non sky) , winters too. It is a bit thicker but molygen has extra lube stuff. I do run this oil with higher flowing oil filter.I mistakenly purchased 5w-20 on my last go-around (Pennzoil Ultra), and changed it anyway. The consensus from bobistheoilguy is that it won't matter much now that it is late spring here in Canada, far from freezing temps.
Could be placebo, could be mind tricks, but I'm finding that the regular slight noise from the valves/lifters (not sure frankly) is definitely greatly reduced compared to the standard fill of 0w-20 from the same brand Pennzoil. 0w-20 with Pennzoil has always been on the "noisy" end.. 5k mile OCI, currently at 55k miles.
I recall you're one of the guys here that beat on the little Mazda 3 more than most, so you're definitely taking advantage of the slightly longer oil life--even towards the end of your OCI, your 5w30 is closer to the spec'd 0w-20 once it's broken down after a few thousand miles than if you had changed originally with 0w20.I have been running liqui moly 5w-30 Molygen after i got to 200K kms (2012 2.0L non sky) , winters too.

What's your OCI, duration between fills, and are you relatively stock 2.0/2.5L?Curious if anyone has been running Motul 8100 ECO-Lite 0w-20 and if so, any issues?
Im at $11 a litre with Liqui Moly Molygen oil.What's your OCI, duration between fills, and are you relatively stock 2.0/2.5L?
Unless you're racing/forced induction/ or doing really long OCI, I don't think many regular folks can justify paying 4x the cost of 5L/1G or amazon/kirkland/pennzoil full synthetic $15 oil changes (for oil).
