I have the same 5sfe engine in 2 Camry's I own, a 93 and 2000. As you can see in my sig, the 93 has over 425k. For years I used 1/2 quart of high mileage oil on top of the 4 quart fill, kinda to fill the oil filter and cut down on oil consumption and a slightly leaky rear main seal. It worked well for me as I used whatever oil I could get cheaply and changed it about 3500 miles. Over the last few years I have found using a fill of all high mileage oil allows me to extend the OCI to 5000 miles. This includes a 95 V6 1mzfe Camry my wife drives. BTW you may have noticed, but the filter for an older Corolla is longer but otherwise identical (Bypass pressure, etc) to the tiny filter for the 5sfe. The puro number is 14477 and I recommend using it as it usually costs the same. If you want to use it, beware many listings and interchange charts show the shorter filter for all the listings so you have to look and see what they have.
The high mileage oil may also help stave off a leaking oil pump cover gasket. The next time you have a timing belt done I'd recommend you get that replaced along with the oil filter adapter and oil cooler o-rings/gaskets. The all harden and start to leak and I like to get ahead of the problem. PM me with any questions and I will try to answer them. I have a lot of experience with 92-01 Camrys.
