Engine oil AMSOIL or RAVENOL

0W-20 Amsoil Signature Series 100% synthetic oil changed every 5k miles. Wix 57173XP filter.

Ravenol user here (previously motul and shell user). So far, engine temp is 1 line lower, quieter engine, and very slightly better fuel economy. Ravenol for the Altis 2.0, yaris, and rav4.

On 2006 F800S i have used Ravenol. I tried Shell, BMW oil(Shell, basically) and Ravenol. With Ravenol- no false neutrals. At stops i was able to find neutral almost instantly... And engine sounds somewhat "greasy"

As an avid user of AMSOIL, it’s a noticeable difference, amsoil is the king

With Amsoil even if it's not signature series I trust it more than any other 0w8.

I run Amsoil and my oil change interval is 25k so the answer is it depends.

I only use Amsoil Signature Series in my B58.

I changed to that and really happy with it so far, shifting is butter smooth.

The oil i have run: VW brand, Castrol and Ravenol all 0w-20 that meets 508/509. Basically on cooler outside temperatures the oil does run slightly higher than on hotter days.

after 2000km of running on it, i see there is quite a drop (30% from the max point). i think that is very weird...
