Hello guys, wanted to ask which oil I should use for the Mazda, have been thinking about changing for weeks. The Mazda has now 222 000 km on it and last I changed at 206 tkm. I just got SAE 15w-40 and wanted to switch to LIQUI MOLY SYNTHOIL HIGH TECH 5 W-40 HD, is that ok or I just scrape the engine with it. would be really grateful for an answer the data still: Mazda 626 GE 2.0 116 ps motor code fs bj 04.92
