Depends...no one size fits all...even with socks...
Full synthetic has higher specifications than dino...though the gap
has gotten smaller
How do you drive? Little old lady to boy racer ? How often each week
does your ICE see max RPM? How often to you sustain it above 80% max RPM?.
How often do you go WOT? If so, how long do you stay at WOT? etc
Where do you drive? Ambients, inclines, altitude, extreme heat, extreme
cold, high rev'ing w small torque...to low rev'ing w huge torque, etc
How often do you push the ICE's oil to it's limits or close to its limits?
How do you manage maintenance intervals? Time based? Mileage based?
Extended service cycle? Type and quality of filtration?
Then factor hauling/towing. PUP to one at MTWR (the real MTWR) factored
by the above metrics
All why I use synthetic in everything...even my lawn mower/tiller/etc
Plus make my own additive brew, even in the lawn mower (TroyBuilt/Honda eng)
Have owned used that burned/leaked/etc so went to jug dino for them
until either rebuilt the engine or sold them
Was one of the first to use Amsoil. One quart cost more than my hourly
of $3.50...it was IIRC, $5/qt...vs dino IIRC, around a buck/qt
