Engine oil AMSOIL or FUCHS

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 run Fuchs Titan Truck 15w40 in my Cummins 6BT, engine was rebuilt about 50,000ks ago, seems to go alright with this oil

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

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.

Get a catch can but that mobile 1 oil you are using is for shit . Amsoil is best for mustangs and the best for that matter period it\u2019s cost but you can run it 25k
