Has anyone tried Penzoil Ultra? I went out earlier today and found it at Pepboys and Walmart. I then went on the Penzoil website and it looks like this is one of there newer oils. They also claim that it cleans out sludge better then Penzoil Platinum which is pretty impressive. It is $28 for a 5qt jug of Penzoil Ultra, and it's $23 for a 5qt jug of PP at Walmart.Here's some more info on it at Bob is the Oil Guy:

I've been waiting to see more UOAs in a variety of vehicles before I speak further on it, but it is interesting on their claims. I should probably do a comparison of the tech specs of certain oils we are interested in and/or using like I did with transmission oils in another thread. Let me see what I can come up with this afternoon and I'll include this new oil.

 

Please do I'd like to see royal purple and amsoil in there also
actually along with castrol syntec and mobil one

 

I've got a good list nearly complete, but I had to contact two oil companies with an information request as their websites were seriously lacking (I won't name names though) and hope to get the info tomorrow, but I'll look for it elsewhere in the time being.

 

^been running pennzoil since 03 and this ultra is new to me

 

It appeasr to be a Group III synthetic like Platinum with a better detergent package then PP

It is all the rage on BITOG forums
