Engine oil AMSOIL or Motorcraft

I use Amsoil Saber. Zero complaints. 50/1.

I use AmsOil 10w-30 in all my small engines. It’s also what goes in 3 of my 4 vehicles so it is in the garage all the time.

since nabasa ko yung about choosing oil ng isang member dto. sinubukan ko yung amsoil . dabest

I did Amsoil once a year about 8 or 7k miles since I live 3 miles from work, decided and went with Penzoil every 5k miles on 2014 4runner. is cheaper and better than toyotas mobile oil

Amsoil, i have used this oil i

n my cars, trucks, motorcycles,  lawnmower and anything else that runs on gas, it's the best.

Amsoil signature series

10w-40 AMSOIL for metric bikes. Bike runs and shifts like new with 30k on the clock

Full synthetic Motorcraft for my Shelby, Roush, SHO, and Focus 1.0 ecoboost.

Ford performance oil filter for the Shelby. Motorcraft for the others.

Why? I had a Ford tech tell me any and all problems they'd ever seen with a Shelby engine involved one that used non-Motorcraft brand in engine or filter.

I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.

and the dealership where it got changed used 5w 20 motocraft they sell ford and thing of tht nature im pretty sure its to thin and wasnt synthetic
