mobil 1 has been around for over 25 years so has red line...so between the 3 I think it's well proven..just about 10 years ago gaskets has finally got in the 20th century*L*
I'm a Mobil 1 user myself, but I am going to try Royal Purple next change. I have that Maxx Gear fluid for the rearend, & so I am wanna see which is going to give me better engine lubrication, & performance<IMG src=smileys/smiley16.gif border="0">
Yes it's ok to use synthetic in your car. I checked on royal purple oil a while back but thought it was extremely overpriced. 8 dollars a quart is a little much. I dont see how it can be much better than Mobil 1.
