Pennziol Ultra
Sorry, but I didn't take any pictures.
I've been using Pennziol Ultra in my 2015 4Runner for the last 30k miles & changing the oil every 10k miles since new (110k miles now). Yesterday, while changing my oil, I decided to clean out my aftermarket aluminum oil filter housing, as I do once in a while. There was black, hard packed sludge in the grooves of the filter housing; Probably about 1/2 teaspoon. I wouldn't have been able to see it with the stock filter housing since it's black. Anyway, I believe the Pennziol Ultra is really doing its job in cleaning this engine and will continue to use it. It does have to be special ordered from Walmart though.
