Why the hype about synthetic motor oils? Do you use it? Do you know why it is better? Do you care? Well you should know a little about the most critical fluid in your engine. It keeps all those moving parts from rubbing each other raw.
Here are some benefits that synthetic motor oil brings to the table when compared to conventional motor oils. These are especially critical when considering the fact that Harley Davidson Motorcycles (not VROD) are air-cooled and sometimes subject to higher operating temperatures then what you might see in a water cooled-engine.
Superior long-term engine protection - (5k service interval instead of 3k - saves money).
Superior high-temperature stability - (Oil does not break down as quickly in high temperature).
Excellent low-temperature starting - (Always a plus on those cold mornings).
Outstanding engine performance - (Oil maintains viscosity longer).
Bike runs cooler - (Always a bonus!)
