I'm considering running Pennzoil conventional 5w20 in my wife's Honda at the next oil change and was checking out both the US and Canadian websites and noticed that on the Canadian one it says that Pennzoil conventional cleans out 15% of sludge on the first interval, while the US one says 40%. So I'm wondering if the Canadian site is simply not up to date or is the formula actually different up here? Has anyone in Canada seen the new Pennzoil conventional with the label stating that it cleans 40% of the sludge?
