Engine oil ZIC or OEM Subaru

SK Zic 5W30 Diesel

Zic X7 5W30 Gas / Diesel

I'm riding a Mio Gear S, and ever since I started using ZIC, the performance has been outstanding. It’s a perfect match for my motorcycle.

Getting 30mpgs in my ‘14 and been running 5w30 for years, smoother and quieter

No issues with 5w-30. Switched my 21 Crosstrek to it due to the summer months coming. Little dip in mpg but the engine runs smoother.

Either way I have the impression that the engine has a smoother sound and feel now, can this be possibile or it's just a placebo ?

They sell Subaru branded Idemitsu at the parts counter

I’ve been using it as well for nearly 50,000 kms now in my personal car without any issues.

0w20 provides your engine with more wear protection .

There is minimal difference between 0w16 and 0w20, with 0w20 provided marginally better wear protection and 0w16 providing slightly better fuel efficiency since it's slightly thinner and provides less internal resistance.

I avoid the 5 minute drive-thru places. One of them wanted over $100 for full synthetic on my Subaru Forester. Not worth the 5 minutes.
