Hello all,
I have a 91 BMW M5. It has a DOHC 3535cc inline-6 with bucket tappets. 7250rpm redline, 310HP/265TQ stock. Owners manual specifies 15W-40 or 15W-50.
I have been using Kendall recently per recommendation by Frank Fahey, a known BMW engine rebuilder out of San Diego, CA.
VOA has left me a bit underwhelmed, a little light on zinc, phosphorus and molybdenum. Any thoughts on the titanium additives?
Next time around, I am considering Mobil 1 15W-50 SN. I considered Castrol EDGE 5W-50 and Mobil 1 5W-50 (Porsche) but am skeptical about using a 5W-XX vs 15W-XX because of the specifications in the manual. I have a factory resonator in place of the standard catalysts.
