Engine oil OEM Mazda or AMSOIL

I runn amsoil's european car formula 5w40 full synthetic and being a mechanic i will vouch for amsoil all the way because i can always tell the difference between good oil and ****

I went 10k on amsoil 5w40 and never needed to add oil.

I use the Amsoil 5W-40 european formula. It was not on the VW oil list last time I checked, but the Amsoil says right on the bottle "meets VW spec 502.00" so I'm cool with that. Amsoil has a great reputation.

Used the rotella for the first 90,000. Switched to AMSOIL so I can change the oil half as often. I'm good with either one. The car has 146,000 and runs as strong as ever.

FWIW, I used Amsoil in my old Mk4 GTI VR6 and in my R32 with no issues.

0w-40 weight oil is great for the VR6. I've been using either Mobil 1 or AMS European Formula (5w-40) in mine since day 1. 85k miles later it still runs like a champ. AMS Euro oil is fantastic stuff, definitly worth every penny.

i used their oil before and was very happy.

I use Amsoil full synthetic 15w-40 year round in my 1.6D with over 250k miles.

Amsoil 20w50 in my 8-v 12:1+ 1.8 liter Rabbit Amsoil 5w-40 in my street turbo Jetta and track turbo Golf.
