Cheap to buy and best to use as to WF and block heater.
I use a grille block made of polycarbonate for the fall and spring once past A/C weather (running solo). Still plenty of airflow to heat exchangers, but temps come up faster and stay up even on highway.
I use the MOPAR WF on my Dodge in winter. Unquestionably worthwhile. The op manual on the Class 8 work truck I drive says the WF must come off at 41F degrees.
Use of the block heater year round is what I would do were I a commuter. 90-minutes gives 90% of benefit.
"Winter fuel" blend is only 5% less energetic. Use of a WF and block heater is good for fuel mileage and engine life. I'd add an oil pan heater.
