Engine oil Shell or OEM Subaru

Been using Shell’s HX7 for 7 years now, so far okay naman.

Shell Long Ride, OP. Tested ko na 'yan and super okay niya. Been using it for a long time narin kaya im sure na goods 'yan!

Rotella t6 5w40 all day every day. Run it in my focus st. I noticed less oil consumption, cleaner plugs and less soot just after the second change

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 ?

But if high quality oil tulad ng Shell na fully synthetic, i go as high as 3k.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

I ran T6 twice and didn't like it myself. I don't remember what it was that I didn't like about it, but I switched to Yamalube and haven't looked back.
