Breezy,
I recommend synthetic. It does not break down as fast as petroleum so I think it's better for a long haul like 700 miles of highway. It may or may not help with the longevity of an engine but if you are like me & don't follow the regularly scheduled maintenance the way you should, then synthetic is definitely the way to go.

I would be weary of switching to synthetic if you don't have the previous owner's documented work. Anyone disagree or agree?
I just switched to my winter weight 10W-30 oil. I normally run 15W-40 Shell Rotella, but because Walmart only has Rotella in a synthetic blend 10W-30 (and I don't really need the extra cost in the synthetic blend) I switched to Mobile "Super" 10W-30 high mileage, and I must say that it smells GREAT! It actually smells exactly like castrol high mileage, so it must be the additives and seal conditioners.
We'll see how this oil holds up.
I changed out all lubricants to Amsoil when I got my VX with 150,000 miles and have had no issues in 4000+ miles. I have no idea what the previous owner was using, as it came with no records...
Rotella full synthetic
I just had Mobil1 full synthetic put in. I hope it was a good decision lol.
I'm still very happy with Amzoil in every orifice that requires lubrication...
how ya get the stains outta the sheets?
I currently run Royal Purple in my Hummer. When I do the first oil change on my VX (have not even put 200 miles on her since July) i'll be using RP most likely.
I've got an account @ sheets-R-us...:yesgray:Quote:
