Ever wonder what oil your mechanic actually puts in their own car? Turns out, they steer clear of bargain-bin brands, flashy miracle claims, and anything that doesn’t match what your car’s manual says. If an oil isn’t on expert lists or tries to sell you on skipping maintenance, that’s a red flag. The money move: stick to brands with real-world testing and clear labels—your engine (and wallet) will thank you later. #Business #Industry #CarCare
