15W means, if you're suffering from low injection oil pressure, you have real problems.
Forget "cycling", the GPs don't turn-off when the light does you can just leave the key on. In fact, sometimes the light is ON and the GPs are not. It's just a timer not a real indicator.
BUT, you don't need them at ALL, at these temps, if everything else is right (typically, peoples GPR completely fail now and they don't even know it until November comes). Something else is bad...
