Since my last LR4 scheduled maintenance I've done 3 or 4 extremely dusty runs on dry dirt roads. The dust caked up on the rear, infiltrated the doors and such. Car wash and dust rags got most of it, but left me wondering about the air filter.
Do I need to clean the filter? Or replace it?
What is your experience, practice and advice?
Being from Florida, I've never seen dust like this. I know the effect of dust clogging a chain saw filter (no power, hard starts.)
Is dust in the engine filter killing millage and power in the Land Rover?
Is this the only filter I have to worry about?
Or am I worrying for nothing? Can I leave the filter as it is for 6 months to a year for the next scheduled maintenance?
