Engine oil LIQUI MOLY or OEM Mazda

LIQUI MOLY Engine oil

155k was using LM molygen and recently switched to LM leichtlauf. Three oil changes with the leichtlauf. The difference for me was i was topping off with the molygen vrs the leichtlauf never needed to top off between changes.

Pros: less topping off needed
Cons: topping off with molygen
Mileage: 155000 km

OEM Mazda Engine oil

I encountered something similar when I took my CE Turbo in for service a few weeks ago. The invoice said 0W20 and when I asked the service manual why they used the wrong oil they told me “oh our technicians know what oil to use, ignore that.” Needless to say I have zero confidence that the correct oil was used.

Cons: wrong oil used
Vehicle: Mazda
