I use Valvoline XLIII and it works great and not terribly expensive.

Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.

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.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there

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
