Oil Debate started :devil
I think he's talking [email protected]
The MB Engines on the fleets I have looked after over the years all have regular early Oil & Filter changes, around 5 - 6000 miles........
All are original Engines, the newest is 2007 MY Vitos with 275k miles, and the oldest is 2003 Sprinter with 380k miles, all run superbly and don't use significant amounts of Oil.
Further to this, the 2 x 2007 Vito's both had Auto Boxes Rebuilt by me last year at @ 250k miles and these were still driving OK, just had Converter shudder :wink The Trannys were in good shape internally, and these Trans had Fluid /Filters done every 50k Miles :wink
There is no substitute for Clean Oil and free flowing Filters, also stops harmful deposits building up inside the Engines, which can clog Piston Rings, Oil Galleries, Pump Strainer, Piston Skirt Spray Jets etc etc etc
Similarly on Auto Boxes, stops Gumming of Valves, Filter flows freer keeping supply of Oil Pressure up on demand etc etc
