A good quality oil filter much more important. I saw study where major trucking firm only changed oil filter every 10,000km, they found oil showed no wear metals until ~50,000 km.
Well....Cummins and Detroit's oil change interval according to thier own specs on highway tractors is now 100 000 kms...
