Member JLTD gave me (3) gallons of 5W30 Amsoil SS (Thank You JLTD). My son did an OCI to my F150 (6 qts.) and his F150 (7 qts. he bought an extra qt. of Amsoil SS) in June 2020. His lost about 3/4 qt. in 7K miles. I checked my oil today and it's down about 1/4 qt. in about 2.5K miles. My truck has NEVER lost oil before this Amsoil OCI. And, my sons truck has NEVER lost oil either before the Amsoil OCI. Is it POSSIBLE that the Amsoil is causing the loss? If so, how? Both trucks are not leaking oil and there is no oil being burned either. My sons truck has 80K miles and mine has 159K.
