Thank you for your inquiry,
Mobil1 15W50 Extended Performance would be the appropriate product for your applications, it contains the higher levels of ZDDP levels. Energy conserving motor oils have mandates put on them to reduce ZDDP levels.
Thank you for choosing ExxonMobil products.
If you need further assistance, please contact ExxonMobil at 1-800-ASK-MOBIL
