I put Auto RX in my car, drove 100 mles and then parked the car for 5 months. This was my second cycle of auto RX in my Passat. About 30 minutes into driving (after being parked 5 months) the oil light came on. I kept driving because I have read about sensor blockage before.
My question is the oil RX still good, should I replace it, give it a booster shot??
No need to add ARX just drive it, as Auto-Rx cleans as you drive and and not the amount of time it is in the oil pan or engine.
Strange sounds-blinking gauges all telling you your engine was full of contaminants and Auto-Rx has cleaned off these areas and oil for the first time is lubricating them. These will go away after your done rinse cycle. They do not signify problems. Hope this helps.
