Re: Oil, son. . .black gold. . .Texas tea
Well, my observations are just that... But I use only Mobil 1 full synthetic in my 454 (the engine I have that I really care about, I don't use anything but the relatively cheap stuff in the little 2.8L, because I don't care if it sticks around or not, if not, I get an excuse for a swap [img]/wwwthreads_images/icons/wink.gif[/img]). I actually seem to have gained a little power, and it seems to actually run a bit better now. However, I think the thing that makes the absolute biggest difference with oil, no matter what type, is changing it often, and having a really good quality filter.
