Those of us who have taken several vehicles past 300K on conventional oil know better.
If you want to waste $$$ on "sinthetic"...go for it.

I said "Yes, the manual does say 5w30 for the 3.5L V6."
Where did I say the MANUAL says to use synthetic?
You won't find it because I didn't say it.
I simply said WHAT I USE.
Your statement " Synthetic was created to increase profits for Big Oil and they knew it could be sold easily to the unknowing."?
Synthetic oil is part of a Big Oil conspiracy?
Come on...
In my personal experience in high performance engines, running Mobil 1 instead of ANY conventional oil I've tested, made the engine run 5-7 degrees cooler.
That tells me using Mobil 1 reduces friction.
Synthetic also resists heat breakdown under hard use.
I also like the fact that synthetic also flows better on startup in cold weather.
It's disappointing to now learn that my current high performance big block Chevy isn't really running cooler with less friction, it's actually part of a Big Oil conspiracy.

(what, are there little gremlins who work for Big Oil under my dashboard? And when they see that I put Mobil 1 in my engine, they get inside my fluid filled temperature gauge (hope they can hold their breath) and hold the needle from going as high? ) LOL
Seriously though, if you like conventional motor oil, use it.
I'm not going to debate you or anybody else.
Just use what you like, and I'll use what I like.
