I am the owner of a 98 Corolla with about 150,000 miles and it's been burning about oil between changes for about the last 50,000 miles. I have to add about 3-4 quarts of oil between changes. No leaks or big clouds of smoke. Someone on the Toyota Nation forum recommeded Auto RX and I want to give it a try. Apparently, this engine is somewhat notorious for burning oil. As far as i can tell I do not have a sludge problem.
What I'd like to ask is from those of you that know better what would be the best way to proceed in terms of application/rinse cycle and recommendations for best oil to use while I do this.
Thanks in advance. Hopefully if all goes well my mechanic is going to be monitoring the car - he's interested in Auto RX as well.
I would go to the Auto-Rx site and look at the instructions under heavy oil burning, as far as an oil I would use the cheapest dino oil for the clean and rinse phase, I would also recommend that you change your PCV, be patient as it will take time to get results. As far as oil filters go I would get the cheapest ones you can get your hands on, Wal-Mart Super Tech is the cheapest dino oil I know of, stay away from oil's labeled high mileage.
I agree with Brent down the line. I would also suggest using the Supertech filter during your application. Also don't use any oil labeled "synthetic blend", just plain old conventional oil (follow manufacture recommended viscosity)

Perhaps has dirty or stuck ring packs. Perhaps has contamination encasing valve stem seals. Perhaps has a malfunctioning PVC system. ARX can definitely help with the first two. PVC can be easily serviced if found to be non-functional. Sounds like a very consistant level of oil entering the combustion chamber. Provided no parts are severly damaged, ARX should bring this unit back to an acceptable consumption level.
O.K. Just got the oil changed and added Auto RX- also got the spark plugs changed along with the PCV valve. Had my mechanic check the compression on the cylinders - 200/175/200/180. So I'm going to go by the heavy oil burning guidelines as there are no bad signs of a sludge problem. I'll keep everyone posted on the results - both on iol burning and compression.
