I Dont use or recomend synthetic oil to my customers for two reasons

first motor oil gets contaminated over time with unburned fuel and
byproducts of combustion that the filter does not remove and synthetic
cost more so the average joe wants to leave it in longer

second the synthetic oil does not absorbe the heat from the heads the
way that petroleum based oils do and thats a problem for both the air
cooled and the water cooled engines
hotter heads make less power and degrade valves, guides and outer rubber
coolant gaskets on the waterboxer at a faster rate
