Synthetic vs. Mineral Lubes for Gears
Every engine, from those in the smallest toy trucks to the ones in expensive high-end vehicles, uses gears of some kind. These gears transfer movement from the engine components to the axles – which means that they need to be in proper working order for the vehicle to perform at its highest standard. And with constant friction, hard metal parts, and often-dirty work environments, keeping gears lubricated is a must if you want your powertrain to do its best.
When it comes to lubricants, there are two kinds to know about: synthetic and mineral. Synthetic is more expensive, but more stable; mineral is cheaper, but not as versatile in extreme temperatures. How can you know which one to use on your powertrain gears?
