What's the manual read to use? If it's 5W30, why can't you use Pennzoil Conventional 5w30? It can handle 5K miles very easily.
How do you see what the car “feels like” on different oils? Do you have a discussion with it?I'd run a full syn; It's hot down there. You gotta see what your car feels like on different oils, then, pick the oil your car "likes."
Most drivers can notice the engine running more smoothly or more quietly with one oil vs. another oil.How do you see what the car “feels like” on different oils? Do you have a discussion with it?

5w30 per the manual, 5w-50 is for the V8 engine.
