Engine oil VALVOLINE or AMSOIL

I ended up returning the Castrol Edge 5W-40 and got AMSOIL European Car Formula 5W-30 Improved ESP Synthetic Motor Oil instead, which is VW Approved and 504 spec. Its quite pricey though, $180 CAD for 12 x 946ml.

Amsoil XL 5W-30 in my 2016. Swapped with a new OEM filter every 6K.

I've been using Valvoline #VV966 VW502-approved full synthetic 5W40 MST on our Audi and the GSW. Works well, no issues.

I run Valvoline simply because when I got my Civic people recommended it. Hasn't given me any troubles yet even in my Miata.

For my Ford I use motorcraft because it's oem.

For my high mileage Honda I've been experimenting with how the oil "looks" after a change. I know it's not technical but the valvoline oil seems to hold up well.

I've used Mobil1 many times but my last oil change I decided to use Valvoline 5W-40 MST SynPower which is actually on the list as a 502.00 oil.

Valvoline full synthetic 0W-20 changed every 5k, oil filters I prefer oem but recently it’s been whatever is on sale at advanced auto

FWIW, I've run AMSoil in my 2003 WRX since new, and I like it. What actually sold me on it was when I did my first oil change. The used oil still feels new when you run it over your fingers. And the engine still runs just fine.

I'm one of those people that uses Amsoil. I use their European 5w40 and change the oil every 10K or 1 year, whichever occurs first. Never needed to add any oil between changes.

Just changed oil today (same oil as above) at 104,728 miles. Purrs like a kitten.
