Mobil 1 Extended Performance oil

[Y_K]

It is a common measurement error with torque, when there is a lubricant present, and the plug is well oiled

Main cause of flying spark plugs in Ford modular v8 and anal mechanics with $400 Snap-On torque wrences: they put too much anti-seize and throw the torque off

1 year OR 15,000 miles means,if 1 year comes before 15,000,then change it at 1 year. PP seems less durable in my app than EP. I run 6 mo. apprx 4,000 mile ocis with EP. Hard to gripe about the $35 deal.
