Pennzoil Platinum 5W30 has a flash point of 207 degrees C, while in comparison Mobil 1 5W30 has a higher flash point of 242 degrees C. That is a bit of a difference should you have an overheating problem in the summer - is this due to the gas to liquid process Pennzoil uses as compared to Mobil 1 ?
Reasons For Pennzoil Platinum 5W30 Poor Flash Point ?

I would also look at SDS Sheets for both of the oils you mentioned. Are they both run using the same testing method. I have seen different Flash Point Numbers from what an oil company lists on there website versus the SDS Sheet.

Not measured the same. One uses ASTM D92, the other ASTM D93

This is why it's important to pay attention to data sheets before asking questions.

Why look for information on your own when you can just make a thread asking for it! Gimme gimme gimme
The QS FS 10W30 I have suggested for use with D.I. engines (in moderate temps) has a FP of 240degC (ASTM D 93)
Because "synthetic" that 5w30 is light oil mixed with goo and the 10W30 is thicker oil mixed with little-to-no goo.
Don't be fooled by the Platinum marketing moniker on some Shell products, it just means its for use with cars with catalytic converters that haven't been sawed off and stolen ... yet.
