Mobil 1™ 0W‐40 contains: Phos: 1000 PPM
Zinc: 1100 PPM
Sufficient
Zinc and Phos for roller lifters. I would not recommend for flat tappets due to the need for higher
Zinc and Phos requirements for those engines.
OW for those cold early morning start-ups.
"Has excellent low temperature capabilities for rapid engine protection at start-up" from Mobil
"High performance engines Most operating conditions, from mild to extreme"
From Mobil.
Happy motoring.
