Engine oil Mobil or PENNZOIL

Best bang for your buck is the ultra premium penzoil 0w 20. Meets the api certification and in terms of performance it essentially provides the same level of performance as the amsoil.

My oil report on 0w30 mobil1 esp looked good. I'll keep using it. Mix of track and daily duty.

I run Pennzoil Ultra Platinum 5w-30. My FK8 is making over 500hp no issues

Seeing good results, lower heating, smoother functioning with Mobil Super Moto 15W-50 Synthetic Technology Engine Oil.

I was riding in the Himalayas where low-gear, high-acceleration could not be avoided and decided to try this. Noticed better performance, lower heating and decisively moved away from RE's semi-synthetic.

I wouldn't limit yourself to VW brand oil only if another "approved" oil is cheaper. VW has a document listing which oils meet their spec. I use the MOBIL 1 Esp x2 (it's on the list) since the 5 quart bottles are usually cheap from Walmart.com.

I’ve ran mobil1 5w30 for a few years now with oem filter on my 1990

I use 10w40 also from Mobil 1 high mileage. A lot of our engines will have a tick on start up or once hot, if so with your Motul, switch brands to another top tier on next oil change and see if your engine likes that brand more.

For the money, Pennzoil can't be beat, and I say that considering you can usually get it from Napa or Amazon around $7/qt. Idemitsu is also great, but hovers around $8 or $9/qt on Amazon or Napa.

I used to do 10k mile oil changes with Mobil 1 EP.

If you run Mobil1, yes you will needs lots of extra oil... Mobil 1 doesn’t make the grade.
