suspicious review by "Someone" using wrong viscosity
Username Someone says, "Horror. The oil thickens for unknown reasons and chokes the engine. Like a glue." If that's true, it's probably because he used 10w-40 in cars that call for 5w-30. Misapplication equals product bashing? Like there already wasn't sludge in a 20 year old beater and other older cars? Also in the USA Magnatec is full synthetic.
