Engine oil Castrol or AMSOIL

Always used Castrol in my cars when I\u2019ve had the choice and never had a problem.

Have noticed on several times that when I went from Subaru OEM oil to Amsoil BACK to OEM that it runs much quieter and smoother on Amsoil.

But I run Amsoil signature blend in my vehicles. And I also push 15,000-25,000 miles per change.

I have seen my friends and family use amsoil for 25000kms each change and their cars do 200k- 300k without any engine issues.

On my previous car, a VW Golf 7 2.0 TDI I used to change the oil (Castrol 5W30 Long Life) every 12000km.

I already added to engine oil and transmission. 5mpg improvement avg. already.

Switch to Amsoil products and go every 6,000. I honestly would go every 7500 with it if it was me driving that much.

Had an 02 explorer with the 4.0 that had 286,000 and still running like a champ when I sold it. It was on its second transmission and everything in the vehicle was falling apart but that motor never once had an issue. Regular maintenance and oil changes every 10 to 15k using Castrol GTX fully synthetic

Al producătorului, Mobil1 sau Ravenol în general. E ok și Castrol doar că în experiența mea se înnegrește mai repede și trebuie schimbat mai repede pentru o funcționare lină a motorului.

I tried Castrol and was not a fan, found it burned faster than any oil I used.
