Owner reviews for engine oil

Used to work closely with Peugeot and talked to their technicians and customers. Their old Prince engine insists must use Total oil. Nasim (previous owner of Peugeot Malaysia) once used Petronas Syntium and they experienced knocking and oil leak. After using Total, it eliminates the problem entirely.

Op I was told by mechanic from liqui moly that this engine oil was the best for pick up

Redline 5w30, the best

Liquid Moly Molygen 5W-30, haven't had any issues in the 22k plus miles I've been using it

Using rotella t4 btw.

I have ran Amsoil since day one on my 2016. I change oil once a year currently sitting at 156,000 miles, no issues knock on wood.

Been using amsoil for a little over a year now and it's really quiet.

I use Pennzoil ultra platinum and my car runs great I change it every 5K. I use mazda oem oil filters since they don’t have the anti drain back valve.

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines]

I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that.
