semi synthetic oil and changeover

I have an 88 toyota pickup and am thinking to switch over to
semi-synthetic oil. I am thinking of doing an engine flush first and
then going semi-synthetic.
It has 190000 Km and loses a bit of oil in the summer, no burning of
oil though

Any web resources, information would be greatly appreciated.

I am curious about the following:

Is it a good idea at this age vehicle?
Should I go full synthetic?
Do I need a special Filter?
Do I need to do an Engine Flush?
Once I switch over, can you go back to regular oil --I imagine one
should stay semi synthetic.

Many thanks in advance

Don't bother unless you intend to extend the time between changes, or intend
to run in very hot or very cold conditions.

Don't flush.

If you change go with a full synthetic.

I run in Calgary AB so cold not so hot

why full vs semi

why full vs semi
why not flush?

I am in calgary so cold but not too hot

why full vs semi
why not flush?

I wouldn't recommend switching to any synthetic on an older engine
like yours. In my experience, they tend to use oil when using
synthetic. One Toyota I had just turned 160k miles so I decided to
use synthetic on it. It started using up oil. When I switched back
to standard oil, it didn't use any oil like before. The molecules on
the synthetic are apparently smaller and leak through seals. It
doesn't seem to be a problem on the new engines.

Don't flush. Those things are designed for engines with heavy sludge.
Unfortunately, the liquid is so thin that it is actually very
pernicious to your engine as the parts aren't protected by the oil
like it's supposed to be. Again for the wellfare of your engine, DO
NOT FLUSH!!!

Very much appreciated, I will not flush
