Hi guys i work in Quaker State and what you get using synthetic oil is more times between oil changes, thats all, synthetic oils have a wide range of viscosity that goes from 5 to 50 , and thats wath matters, in the owners manual of my pathfinder says that a 5w 40 can be used , and that applies to normal multigrade oil as synthetic oil. So there is no problem using them, you can take like a year witout having to change it.
