Engine oil AMSOIL or ZIC

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

I use AMSOIL 5W-30 for both of our vehicles. Never had any issues on either vehicle using AMSOIL.

Amsoil Signature 5w-20 + K&N Gold oil filter (HP1017 for 4th gens, not sure about 5th) is arguably the single best combo if you can afford the oil. Your lobes will thank you.

Better to use ZIC X7 fs oil. Korean oil.

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

The first thing I did was change the oil using a wix filter and Amsoil signature series 5w30. The verdict is that the oil has plenty of life left and could have easily run longer.

Amsoil W20 I got a 5.7 it’s been great to me

Amsoil Signature Series 0w40 is an outstanding oil I run it with the SRT filter.

I am a big fan of amsoil. I purchased a used F150 in 2012 . It had 80,000 miles. The first thing I did was I changed the engine oil, tyranny fluid, and front and rear end lubs to Amsoil. It now has 242,000 miles and just keeps on running.

Suggested I change oil from Castrol Syntec to maybe Royal Purple or Amsoil.

I have used Amsoil, but I feel as if my motor makes a funny noise with that in it.
