I have an '02 1.8 with 114,000 miles. Was getting the oil changed at cheapo places until last 2 changes and put in Mobil 1 10w 30 high mileage. Yesterday got the low pressure light on my way home. Drove another 2 miles or so and when I got home added a little bit of oil and drove another 1 mile and light came on and stayed on. The car has sat since then. I did start it up again today and engine is running rough. When I checked the oil it is very dark so I assume that I have the dreaded sludge. My question is should I try the Auto RX now or is my only option to just bite the bullet and pull the oil pan and clean the screen? Is there any other options up front that are somewhat less expensive/ costly/ time consuming? I am not a mechanic but am not a total idiot. I changed the half axels and can do oil changes, brakes, alternators and what not but dont want to get in over my head. Any advice or help would be greatly appreciated.
