I found the OEM Honda filter to have the most filtering surface (908.96 cm2) as opposed to FRAM (553.28 cm2) and Canadian Tire (538.72 cm2). Thus, it results in a reduction of filtering surface by 39.1% (FRAM) and 40.7% (Crappy Tire) over the OEM HONDA oil filer. Perhaps it is interesing to mention that FRAM and Canadian Tire filters are made of the same parts. The only difference between the two is the fact that FRAM has more filtering surface (One more paper pleat to be exact). Finally, all three brands of filters seemed to hold the same amount of oil after the engine stops, which to my surprise was a lot given that you take the filter apart. The stopping valve which is supposed to be only in OEM Honda filter is also found in 2 other brands. Nevertheless, all these comparisons unfortunatelly do not give a full picture of what is the actual filtering capacity of the filtering material. Consumer Reports has tested some oil filters in 1987. Many thanks go to Robert Neidorff for sending in the article.
to punch a hole on the side of the oil filter to dispose all of the used oil. You'll be surprised how much more there is! Thanks in advance for making the environment cleaner for all of us.
The best way to change the oil is to drain it overnight first, than in the morning get the oil filter off. Every time I do this, oil filter is empty. SO I GET NO MESS.
