Simply put, we reformulated Signature Series Synthetic Motor Oil to solve problems. For all the derision heaped upon the internal-combustion engine, it remains our primary mode of propulsion. And, despite the gains of hybrids and electric vehicles, it will remain so for the foreseeable future.
Marco Navarro asks on our Facebook page about break in oil, with attention paid to powersports engines. Thanks for the question, Marco. Let’s get to it. Maintaining an engine is a constant fight against wear.
