Engine oil AMSOIL or ZIC

Fellow mu-X owner here! If you're thinking about upgrading from the standard Isuzu Genuine Motor Oil 10W-30, check out the ZIC X7 Diesel 10W-30 Fully synthetic. I used Amsoil Turbo Truck 5w40 too (10k km interval) but it's expensive for my Garage queen mux haha. Mobil Delvac1 5W-40 is good as well.

I have Signature in my 25. Smoothed out the engine noises quite a bit.

okay naman ang Zic, which variant will you be using? Sa office namin halos lahat ng sasakyan, trucks and forklifts included, Zic X6000 ang gamit namin in the last 5 years, never had an issue with it

Engine noise is a little, well noisy, mine is less rumbly/vibrationy after I changed my oil and used Amsoil Hybrid oil. I can’t generally feel anything when the engine kicks on now, before I could definitely feel it every time it kicked on.

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

My 2016 GT350R has almost 25K miles and has never needed oil between changes. I use Amsoil every 5000 miles, sooner depending on track abuse.

Amsoil 100%, I tested it quite a few, and I’m noticed the least amount of decoration and power loss with it

5w30 Amsoil, ignore the tick it's normal.

My biggest regret, not swapping out the shitty 0w-20 factory filled oil for some 5w-30 Amsoil, Motul, or Pennzoil Ultra platinum the moment I took it home. Don\u2019t wait till 1k miles.

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.
