Engine oil Castrol or RED LINE

I use Castrol Synthetic 10w-30 on mine.

It’s thicker oil, so I feel like it gives the engine better protection. With 272k miles on it, I figured why not.

I’ve been running Castrol GTX 10w30 conventional in my 9000 Aero. Brought it to a Saab specialist and he recommended it. Need to have the valve seals redone and the oil is thick enough that it doesn’t get past the seals and no smoke. No issues running it. I change it every 3 months regardless of how far I’ve driven.

Good results with Castrol Edge Euro full synthetic. No issues. 138,000 miles, no oil consumption or smoke.

I’ve used Motul, LiquiMoly, Molygen, and Redline 5w40. Oil analysis was best with the Redline, but it’s pricey…although worth the better numbers IMO.

Castrol is great option if it is not fake, also make sure to change oil every 10000km (6200 miles). Those engines are bulletproof, should cause no issues

Castrol Edge 5w-30 Full Synthetic Euro Car. It carries the BMW Longlife 01 cert.

I use Redline 5w-40 because I noticed my engine burns a quart every 2000miles using other brands or thinner grades. With RedLine there is barely any consumption.

I recently did my first track day on a day with 105 degrees temps. I went with Castrol Edge 5w-30 and the car did amazing.

I ran Castrol 5W30 full synthetic in the engine.It burned a quart every 3500-4000.

I noticed when the castrol 508 spec wears. It smells Faintly of onions and beans. Strange smell indeed, when I took my car to street side VW out of Amarillo, Texas.
