My 1996 Avalon has a Toyota oil filter, size 90915-YZZD1 on it. It has gone about 5000 miles. I had my local mechanic order a new tail light switch and do some minor maintenance. I had him change the oil and leave the 90915-YZZD1 on it. The new oil is clean as a whistle. I want to run the filter 5000 to 7500 more miles? Your thoughts? I think I am doing OK as the engine has 250,000 miles on it.
