Back in the early eighties I remember that Mobil ran a test with a
truck line using Delvac-1 (diesel eq to Mobil-1). They did change the
filter per mfr specs, but did not change the oil, Only made up what
was lost during the change. I lost track, but I remember that at
250,000 miles the oil still tested within spec for the oil. Following
that lead, I began to change oil once a year, but change the filter
every 3,000 miles (an easy thing to do in a Camry.) Put 189,000 on the
car with never a miss. AFAIK, the car is still running today. On my
next Camry, I did the same thing. At about 80,000 miles there was a
factory recall on the engine regarding an oil jelling (whatever that
is) problem. The mechanic told me that it was one of the cleanest
engines he had ever seen before I told him about my maintenance
routine. I have just started the same routine on my Avalon. BTW, the
Avalon uses a cartridge filter like our Healeys. I can't speak for
mineral oils, but I'm a fan of Mobil-1. Use it in my mower, too. Put
it in, don't plan to ever change it. No financial int.
