“You’re driving along, minding your own business, when suddenly—loss of power, a misfire, and a cloud of smoke. For many South African 4×4 owners, this isn’t a ‘what if’, it’s a very expensive reality.
In our latest episode of Recovery Point, we sit down with Derick De Vries to talk about the ‘cold, hard facts’ behind his recent engine rebuild. It turns out that while we often blame ‘over-tuning’, the real culprit might be what’s coming out of the pump.
From paraffin contamination that bypasses standard filters to the ‘softer’ pistons of certain popular engines, we dive into the rabbit hole of fuel quality. Why are so many D4D and GD-6 engines hitting a wall at the same time? And is the diesel we get in small towns truly safe for modern common-rail systems?
We also discuss practical solutions:
✅ Adding a secondary fuel filter.
✅ Why dropping and cleaning your fuel tank is vital for older vehicles.
✅ The role of injector cleaners and additives in the African context.
Don’t wait for a hole in your piston to start taking fuel quality seriously.
