Ford says 10,000 intervals are acceptable on any oil meeting gf5 so in stating that what makes synthetic better for the average people? I understand it used to be able to go longer and last longer but is that really true anymore? And if it is can it go enough longer to justify the costs? Just me pondering things. As always pictures of engines and how clean or dirty they are is always cool.
Well maybe Ford says that but not every manufacturer does.
My reasons? Well the 1MZ-FE in my old Sienna has a well know reason, I'd be looking at short intervals on conventional oil that would be a lot of hassle. And my BMW and Honda are driven by my daughters, both at school, and I don't always know when I will see the car next. So I use Mobil 1 Extended Performance and shoot for a 10,000-12,000 mile OCI, but if I don't make it because I don't see the car at that mileage it's no big deal. As for the Echo, considering the narrow price differential between conventional and synthetic I really don't see a reason to use anything else.
