All the synthetics I've tried, NOT many, have not lead me to like them better than non synthetics shruggy work
All multi bend oils, 5w20 to 20w50 have some synthetics molicules in them to get them to be rated a different weight when cold versus hot work
If it ain't broke, don't fix it up twocents
5w20 WT Valvoline and VR 10w30 for me up
