Mineral, or conventional motorcycle oil, is a budget-conscious choice for older engines. Yet it still offers all of the Castrol liquid engineering you need.
Motorcycle Mineral oil is at the other end of the spectrum from Full Synthetic. The most budget-conscious option, it is ideal for older engines because full mineral oil provides greater cooling and improved protection, though this can be at the expense of raw acceleration.
It’s also worth noting that while Castrol’s motorcycle mineral oils feature advanced liquid engineering such as Trizone Technology™ and Deposit Control Formula, all mineral oils break down more quickly than synthetic oils and need to be changed a little more regularly.
