Re: Low Cost Oil Filters
I have purchased & installed Canton Racing Products engine oil filters for my cars.
These are rated at 8 microns. The best that I have seen with spin on filters is 30-40 microns. Recognize that there are clearances inside the engine on the order of 8 microns.
I have also installed a bypass flow filter rated at 1 micron.
I think the finer filtration is worth it. I can show a step change improvement in MPG with the installation of the CRP filters at 100,000 miles on my Mustang.
