i read somewhere that mobil one isn synthetic anymore cuz it lost a lawsuit with gtx so its "synthetic" but not accully fully synthetic. but i cant find that article, the guy did an awesome right up with real ways of comparing oil but this was done in like 2010/2011 i believe.

I used Royal Purple and truck ran awesome then switched to Amsoil and the truck didn't run so good for some reason.
Switched back to Royal Purple again and she's loving it.
Guess my baby is picky and she definitely showed it to me.
I have the 5.4L

I added Royal Purple to the poll since it was mentioned a couple of times - I hope the OP doesn't mind.

Thanks for the overwhelming response. I will be coming up on the 10k in the future and want to swap to Full Synthetic. I wanted everyone's opinion as to which oil and why.

I think they are all good. I used Royal Purple in all my cars, the only thing I didn't like about it, and I know it has nothing to do with how good it is, but it's a dark oil. I ordered Amsoil and it's really a light color comparatively, I've switched and really like it. I researched oil filters too, and Amsoil, Wix, Mobil One and Royal Purple seem to be the best.

Oh my God the which oil is better thread. This thread is on every site I have ever seen. On the vette forums people have almost come to blows over what oil they thought was best.

After about 3000 miles have the oil analyized at a cetified lab (you can find them on the internet). That is the true proof of if the oil is performing properly. In almost ALL cases there is not a nats ass difference between all of them. The only negative I have ever seen was Royal Purple seems to break down faster with heat than most other oils. Again, if you change your oil regularly you should be fine with any synthetic.

i use Amsoil cause it seam to be a good oil and is highly acclaimed plus i can get it shipped to my door for cheaper than i can get most of the others.plus like Mudblood said most synthetic oils these days are pretty good and really can't go wrong with most so it really comes down to price and availability.
