What do you think?
 
Does this stuff look any good or is just cheap oil loaded up with additives?

Are you still thinking about user 76 10-30?
I was at a local oil distributor in Brewster Ny picking up some GulfTEK 10-30 and saw cases of 76 and was wondeering which oil would a better choice. I checked both data sheets it seems 76 might hold up better, although Gulf is only a syn blend.

that was my first time at a oil dist..man thet has a little bit of everything.
 
Cauto,

Thanks for the info. When my stash gets low I plan to pickup some 76; $2.05/qt is a good deal. Let me know how the 10w30 runs. Are you going to use it in a 5w30 car? Also, is that the distributor on Rt 6?
 
No I only plan on running 5w30 in that car minivan. I'll be running ARX on the Chrysler minivan soon so I'll have to get some conventional. But after I hope to get 76 Synthetic Blend 5w30 and run it in the van. I bought the 10-30 for my 04 GC 4.0.
