Owner reviews for engine oil

I have a 2010 civic si, I use shell rotella T-6 5w-40 due to burning issues and one quart of Castrol 5w-30 high mileage full synthetic (I’m picky lol- but my car runs smooth and has consistent oil levels on the dipstick through the weeks after oil change)

I tell you the stuff really works. My 2009 Matrix used to burn oil before I switched to Valvoline Restore and Protect.

It's funny, I am now annoyed if I have a service due on my ICE vehicles. Ugh, oil change.

Mobil1 0w-40 Full Synthetic

I switched oil to AMSOIL signature series synthetic, from everything I read, it out performs other oils, used to use Mobil 1

i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half

I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.

That stuff ROCKS! Cured my stuck piston rings issue on my 201O Acura J37 engine.

So recently I’ve noticed that on startup I get a little white smoke that dies down after warming up to about 170 oil temp I noticed this after I changed the oil I used the same green liquimoly oil my gti has been stage 2 tuned for abt 5k miles now, stock is20 and it’s a mk7 tuned it at 100k miles I’m thinking pcv. my peak boost has gone down one psi and I remember it used to hold 28.5 right before I up shifted now it’s only 26.5

I’m currently living in Korea and switched to a ZIC SK Enmove X8 5w-30 full synthetic and OEM Kia filter 26300-35505. Pretty much directly after ticking started.
