I had an Ultracool oil cooler installed on my 2016 Heritage Softail Classic. For those not familiar this is a thermostat and fan assisted oil cooler. Not cheap at $490 but worth it if it lengthens engine life. Now if stuck in stop and no go traffic the oil will still be cooled anywhere from 20 to 40 degrees depending on which review you read. Here in Tucson our temps have been running from 100 - 114 degrees and the engine was throwing off tons of heat. Anyone else on here use one?
