Camry 2002, 65000 miles, any problem if use once synthetic then switch back
to mineral oil? I heard that having to stick to synthetic once you made the
step is a myth.
Always changed oil between 3000 and 5000 miles depending of usage. Do I have
to use a better grade of oil filter than Purolator if using synthetic oil?

Oil companies market blends of conventional and synthetics. Mobil even
said you can mix them so I don't see why you can't switch back. You
can ask Mobil of course.

IMO Purolator's premium line "PureOne" filter is the best there is.
Purolator has merged with Robert Bosch Corp. So either the PureOne or
the Bosch Filtech is fine (both are ~$5.99). It's all I use with dino
or synthetic oils.

I don't think you want the Purolator budget line, called "Premium-
Plus". It's an econo line filter and IMO just aren't good enough any
more for today's engines. You can get these $1.99 on sale at Pep Boys!
Purolator markets these as a social service ;-) ;-) ;-)
