Question:
Correct Oil for Older Engines with Mechanical Pushrods
Do you have an oil for a 1967 Austin-Healey that has the correct additives for older engines with mechanical pushrod and such?

Answer:
Yes, Mobil 1 15W-50 should provide excellent performance for your vehicle. It has boosted antiwear (ZDDP) to help better protect the push rod / sliding cam valve train. The higher viscosity is also appropriate for older engines where clearance in bearings and piston/liner may be greater.
