Engine oil AMSOIL or ZIC

AMSOIL Engine oil

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.

Pros: Fully synthetic
Cons: expensive
Vehicle: Isuzu
Mileage: 10000 km

ZIC Engine oil

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

Pros: no issues in 5 years

Rating 4.0

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.

Pros: less rumbly/vibrationy
Cons: engine noise noisy

Pros: never needed oil

AMSOIL Engine oil

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.

Cons: shitty factory filled oil
Mileage: 1000 km
