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? 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.
