YEP ! talked to a Brad Penn guy and he filled me in on it. I ALWAYS run Kendell and still do but didn't like it when it went brown from green ! He gave me the in's and out's on it and I am thinking of going with Brad penn now.Brad Penn is some of the best oil out there. It's the old Kendall.... made in the same plant in Bradford Pa.
Years back I used Castrol GTX 20-50 and that stuff kept my engines clean....too clean. Seems to be that oils with a lot of detergent have less lubricity. After tearing down 3 different engines and seeing what they looked like inside as far as bearings go.....I quit using that crap. Don't know how it is today but don't care to find out.To clarify my experience with Brad penn, I drive my cars a lot. after long trips, and in the desert heat the oil blackened up pretty bad, and the Inside of the valve covers showed it. It began to look like the crap the Dodge dealer uses when I got oil changes on my Ram. I now use Rotella or Mobil delvac. I don't want to mislead anyone, this is just my experience. I've been around oil since the 50's working at my Dad's Mobil station. and in my view there is a fine line between non Detergent, which caused sludge and pre-mature wear in the old days, and excessive detergents , that to me scours the old engines too much. I found I needed a product that would stick to the metal parts, rather than completely drain down to the pan. The diesel oils in my case eliminated the harsh metal on metal sounds I would get during warmup. the lifters stayed pumped up, and the bearings still had oil residue on them from the previous drive. it isn't just about Zinc, it is the other stuff in the oil designed to Increase fuel mileage in the newer cars. A middle ground product that cleans, but not too much, and sticks around, not disappear, is the best for an engine that is driven on a regular basis. I drive a 69' Coronet 383 HP, and 440 GTX. I don't race at the track,I just do lots of driving.
To bring this thread back to life.....I'm seeing some build up with the Rotella but it's not black. It's more like a golden brown color. I've noticed this on my daughter's PT turbo and not on the others. Thing is her car has 103k miles on it and nothing has been changed except for the timing belt and other maintenance items but she runs 5k miles between changes. I use Rotella in all our vehicles and don't see that on any of the others but I don't really like what I'm seeing on her car. On a 1990 Dakota, I ran Exxon XD-3 (Exxon/diesel 30wt) and that engine looked really good at 100k miles. Thinking about going with the Delvac......
Kendall is a very good product, I didn't know the connection. My experience resembled the results of running Quaker state oil. All foam, all sludge. Yellow, ugly junk.
Kinda doubtful it's gone up.....
