thanks "NormanBuntz", but I have been changing my own oil since I was 17 years old, and I am still changing my own oil, and my relatives oil, at 60 years old... and I never changed oil and reused an oil filter either by leaving it on with dirty oil in it, or by taking it off and dumping the dirty oil out, and putting the same filter back on again.
As I said before in this thread, I only do my oil changes once a year now that I am retired and do not put more than 3000 miles a year on our vehicles, so a $6.00 filter is not worth reusing to me, but like I said, we do not put a lot of miles on a year, and we are in a very corrosive environment here.
The oil is the life blood of our engines....and a full synthetic oil change with the full synthetic filter cost me about $35 to $40 a year to do on each vehicle, so to me it is well worth the cost to use a quality oil & filter once a year...
thanks,
