I have been happy with this oil in any gas engine i have used it in Lubro-Moly- MoS2 Antifriction Motor oil 10W-40 (this is not a link to anything in competition with products sold by this site), it is available from napa auto parts for $35 for 5 liters. When I used it in the milano I used to have it made the engine noticably quieter and increased hot oil pressure over 15w-40 rotella or royal purple oil which i had used before.
