Product Information

The Driven HR mineral oils are designed to work in predominantly pre-synthetic oil applications.

This means they are well suited for high performance engines. They have a unique storage additive that neutralises ethanol and prevents rust and corrosion inside the engine.

It is recommended to replace any HKS filter every 6000 miles or 6 months under normal driving conditions. For sports and/or race use, it is recommended to replace a filter every 2000 – 3000 miles since the RPM and load is increased by several times of that of a normal engine.

Oil filter centre bolt thread M20x1.5 for all Mazda RX7 and RX8 rotary engines after 1991.

We send most oil orders with FedEx. Typically there are 12 x US quarts in a box or 4 x 5 L cans. However, if you order fuel at the same time we'll send the oil on the same shipment as the fuel.

The delivery cost for a box of oil is £9.50 + VAT to be delivered next day. Lower costs may apply if only ordering a few small items. You will see the exact delivery cost for your order at checkout.
