They told me basically I was throwing my money away and my new truck did not need syn oil. Also when should I do my first oil change? Should the break in oil be left in longer than a regular oil change or should I change sooner?
Alrighty---was browsing the Z this morning....found this quote and created a new user name just to reply to it

This is simply untrue.... IT IS A WIVES TALE that once you switch to synthetic you "ALWAYS" need to use synthetic.... You'll probably have that same dealer tell you the two arent compatable.....throw this question back at em when you hear that garbage "How are their synthetic blends then?".... youll get a blank stare or a runaround back....
Modern oils (synthetic and otherwise) are compatable with each other.
Now... the other side of this nonsense from the dealer... "Your truck doesnt require synthetic and you are wasting your money"..
Yes and No...... Depends.... Let me explain:
YES, your dealer is right that your truck doesnt "REQUIRE" synthetic... However that isnt to say you wont see a benefit out of it. This goes into the second half of this statement "Your wasting your money"....
If you do oil changes ever 2500/3000 then YES, you are wasting your money. Take a look at some new vehicles owners manuals and the recommended oil change intervals---most are above 5k---some even up to 8k between changes... You would NEVER get this with dino oil. One of the major benefits from full synthetic is the fact that it has a longer service life (doesnt break down as fast) and offers superior (depending) wear protection than conventional oil.
Honestly---if you want to change your oil every 2500/3000 you would be just fine sticking with a premium conventional oil. However if you want some extended time between changes and/or some additional wear protection... go Full Synthetic or a premium blend (Mobile 1 has ALWAYS been my favorite---whether bikes or 4 wheel vehicles). Royal Purple is good---but Ive never placed much stock in it due to its cost/benefit---and AMSOIL is supposed to be some pretty good stuff.
