Owner reviews for engine oil

As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.

I use idemitsu rotary 20w50

I know this is old, so you’ve probably already made your decision, but I use Pennzoil Platinum. It’s a great oil as well and tends to be slightly cheaper than the Amsoil.

I've used LiquiMoly on euro Diesels before and used 15w-40 oil on my 6.0 Powerstroke this past oil change but really want to get some feedback before I change my oil again.

I use Mobil 1 10w30 with zinc additives. What my local rotary shop recommends and puts in the cars they work on so I assume they know more and better than me lol

I stick to Idemitsu. I have a Sohn adapter fitted, so it's 10-30 Idemitsu in the engine, twice a year and Idemitsu Premix in the Sohn adapter and in the fuel tank.

Personally I rock she’ll rotella 15w40 in the summer and 5w40 in the winter to aid in cold starting. Seems to work pretty good

I use the castrol gtx high mile full synthetic 10w-40 and a sohn adapter with ideimitsu. I’m sure non of the name brands will hurt As long as you change it frequently.

I use Mazda's weight recommendation for my environment, as illustrated in your owners manual. I use 10W-30 and 15W-40 Full-Synthetic oils with zinc additives to stave off carbon deposits.

I change every 10,000 km - 7000 mi.

Castrol or Mobil full synthetic.

To me that is much better than running any brand of oil longer.
