Engine oil AMSOIL or Mannol

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 bought oil last year for 22€ for 10l and I use the HiFlo filter with RC on it. Oil is from Mannol. Full synthetic, what do I need more? All the oil company’s always tell you that they are the best, but they don’t even tell you what the difference with their own oil is. Let alone how they are better then the others.

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

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

Been using Mannol 0w-20 fully synthetic for 3+ years now for my Jazz, engine is smooth, almost all the time I felt the car would always glide and it cruises easily, fuel consumption is great as well as long you are light footed. Mileage is now at 300000km (oil did not reduce at all within that 10000km service interval)

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