Engine oil AMSOIL or FUCHS

After 12 years and 45K miles. I took a 05 Mustang and added a supercharger. For the next three years , and 15K miles, I took it drag racing and high performance track day driving. Wanting more horsepower, I had the engine rebuilt with forged performance parts. When the engine builder measured the wear in the block, everything was still within factory specifications. I had used Amsoil for the life of the car.

personaly I use 5W-30 Amsoil, MANN oil filter and Hengst air and cabin filters

The best talaga ang [Amsoil](https://s.shopee.ph/7KbSRUV7OC)! Tested ko na sa car, bigbike at smallbike. Ramdam na ramdam ko pagiging smooth ng engine after magpalit.

Using 5W30 since deleting the MDS system from my engine. Amsoil Signature, every 6 months or 8000 km.

I called Amsoil and asked about this many years ago. They said for *my* bike, with the 5 speed tranny, they recommended the same 20w50 in all 3 holes.

I run the 5w-40 amsoil diesel oil in mine. No issues whatsoever.

My GT350 gets Amsoil. Had no issues with either one.

Using the same oil but 15W50 for Himalayan. Satisfied with the performance. Even after long rides, the engine feels crisp.

used Amsoil 5w20 last oil change and just did an oil change at ford with motorcraft due to my poor planning… typewriter tick is back with this oil. Didn’t have that at all with Amsoil.

I use Amsoil. While not on the official VW list as an approved oil, it is never the less formulated to the VW spec.
