Hotrod & Classic Motor Oil 15w40 5QT

Hotrod & Classic Motor Oil 15W-40 – 5QT Jug

Hotrod & Classic 15W-40 is built for older engines that still see real use—muscle cars, hot rods, classic trucks, cruisers, and carbureted workhorses. The high-zinc formula helps protect flat-tappet cams and older valvetrains, while the 15W-40 viscosity gives a strong oil film at temperature without being sluggish on cool starts. Perfect for weekend toys that still get driven, not just stored.
