Engine oil PENNZOIL or ZIC

Penziol platinum on my 23. change it every 5k and it’s still golden

Decided in the 5w-30 because the engine seems to run a bit smoother with the 30 weight

Been using Zic on two Hyundais (Tucson, Santa Fe), and ok yung performance niya. Maintained yung cars with fully synthetic, 10k/1 year intervals. Smooth pa rin manakbo ang engine until today.

I use Pennzoil "Ultra" Platinum for my 2010 with 5.4 Triton and it runs amazing. At one point I did try Royal Purple but my engine was actually noticeably noisier so I switched back.

Been using that oil on my Gen 3 Montero since 2020, and ok naman, no complaints.

I only use Pennzoil platinum ultra. Only the finest for my baby.

Penzoil full syn platinum on my 02 and she’s chillin. I’ve never had issues

Better to use ZIC X7 fs oil. Korean oil.

Been using it for several years and it’s amazing for its price.

I usually buy Pennzoil, it's inexpensive and it works. I check the contents first to make sure the oil isn't full of gunk in case someone swapped it. I do oil change every 5k km, which is once every 2-3 months, hence I don't worry much about too much gunk as I flush it out often.

I used Pennzoil before but felt real cheap quality and used to get darker before the competitors. I moved to Mobil 1 or Castrol GTX and felt the difference in smoothness.
