Pennzoil and Sludge!

Pennzoil and Sludge!

Now I'm trying to find out as much as I can about this old time reputation that Pennzoil was renown for Slugging engines.

I want to collect info from both sides of the fence, the technical info to back up that they don't / or do sludge, and real life experiences from engines builders and the general public.

Of cause, if your one of these people that only change your oil once a year then I would expect it to have a sludge problem over time, but I would like to hear as much as I can from the people that do regular changes and there comments and experiences.

I know there are many people that say, this is imposable with the current standards that oil has to pass and so on, but I'm trying to find out where this myth started form, and if anyone has any first hand experiences, past or present.

So I would be so appreciative of any info at all I can get.

Just out of interest, the first comment I have received:

(I recently spoke with one very well know retired engine builder in the states that is apparently well known among Hot Roders, who told me , that over the years of rebuilding engines, he noticed a common sludge issue with customers that were using Pennzoil oils)
