oil and fuel filters

I have been using nothing but CAT brand oil and fuel filters in my 2007 C-7. I have been recently comparing those to other filters and have found that the WIX filters look pretty darn good. Has anyone had any experience with these good or bad. I do change my oil much more often than recommended by the factory. Please give you honest opinion and experience.

    In 50 years of driving the ONLY filter I ever had any sort of problem with was a Wix. I'll never use one again.

    (Plus you buy them from NAPA which has to be war prices)

    I personally don't think there are very many fuel filters that can match the Cat's 2 mircon fuel filters! Know of one other company that makes one.

    There is nothing wrong with Wix filters but you probably won't save very much money over a Cat filter. In fact in my case the oil filter for my C7 was less money at my local Cat dealer than my Wix dealer.:)

    I personally use Caterpillar for oil and secondary fuel filter(would use Cummins/Fleetguard if I had a Cummins) .

    I DO use Wix for air filter, primary fuel filter, hydraulic filters, etc.

    I have a truck not a class A and it has a Cummins and not a Cat, but I use Wix filters and they seem to work well for me.

    Its hard to beat the products that the manufacture use and recommend. There are lots of people that seem to think they are smarter than the engineers that designed the units. I'm not one of them.
