Auto-rx Plus is a highly effective cleaner/lubricant designed to dissolve
sludge deposits as you drive your vehicle. It is designed to run for
basically the whole oil change interval. On heavily sludged motors we
recommend running the Fast Track method. That is adding two full bottles of
Auto-Rx to a fresh oil change. Then run for 3000 miles or roughly 3400 KM.
It is also advised for heavily sludged motors to change out the oil filter
and top off the oil at the 1500 mile mark. These mileage numbers are for
running ARX with a conventional motor oil.
If you plan on running with a full synthetic motor oil, then run the Auto-Rx
fortified oil for 4000 miles or roughly 4600 KM, with a filter change at
2300 to 2400 KM.
As long as oil is free to flow throughout the designed oil system and drain
back to the oil pan, then Auto-Rx is sure to clean. In severe cases of
sludge, more than one application may be necessary to achieve satisfactory
cleaning.
Different types of engine sludge can form. Such as if you have a head gasket
leak and water/coolant has leaked into the oil system, then obviously the
head gasket would need to be replaced before attempting to clean out the
oiling system. Otherwise new sludge will be forming faster than the removal.
OIr perhaps your PCV valve is stuck closed, which leads to sludge formation.
Any idea what caused the sludge? Or perhaps it was just a matter of running
oil change intervals longer than they should have been.
Where did you notice the sludge? Valve train? Oil pan and crankshaft area?
Is it soft and gooey? Or hard like charcoal?
Auto-Rx will always clean, provided that there is not a mechanical situation
causing rapid formation. Or the other scenario where ARX might not clean
would be due to a lack of oil flow to parts of the motor. Auto-Rx can only
clean where oil can flow, as Auto-Rx uses the oil as a carrier to address
sludge deposits. Also if the drain holes in the head(s) are completely
blocked then cleaning the valve train is nearly impossible.
I know there is or were a couple of dealers in Australia. Or you could use
the shopping cart at the Auto-Rx website to get a shipping cost, based on
your physical address. You could just go through the process to find the
shipping charge and then make your decision before finishing to enter your
order.
