I've been using 15w40 diesel motor oil in the AMC/Jeep flat tappet engines for nearly 20 years. Castrol makes a line called GTX Classic that's formulated for flat tappet engines as well

Pros: formulated for flat tappet engines

Castrol makes a Edge Euro 5w-30 and 5w-40 that is LL-01 and ACEA A3/B4, it's not going to meet the later LL requirements because it's higher viscosity and not as fuel conserving, also not low SAPS so potentially it could contribute to more intake valve buildup

Pros: quite good oil

Cons: intake valve buildup

Vehicle: BMW
