Conventional will work fine. If you're changing your oil every 3750 miles, it's pretty pointless to run synthetic anyway, it's more of a waste of money. A good conventional oil will perform just as well as a synthetic for those short oil change intervals.
But hey, it's your money. If putting synthetic oil in your engine makes you sleep better than night, then by all means, go for it.
BTW, if anyone thinks otherwise, please post some used oil analysis results as proof.

Not to get off topic, but what oil are you guys seeing used at your stealership?? My first oil change they used Castrol GTX, which I believe is pretty good stuff, at least for a regular, non synthetic oil. I am going to find out what synthetics they offer for my next change. I will bring Mobil 1 if I have to, never heard a bad thing about Mobil 1.

The oil may last 7500 but I think the stock oil filter may only be as effective up to around 4 -5K miles unless you use after market filter.

either way you guys are taking the whole advice on how conventional oil is supposed to seal engines properly for a while first before moving to the more viscuous synthetic right? I was thinking about doing my first upcoming 3750 change with conventional and then the 7500 with synthetic.....any input?
