Well we all just found out that we are not suppose to use Castrol GTX with Auto-RX. Any other Dino Oils out there that we are not to use with Auto-RX? I bought a case of GTX to do my Auto-RX treatment only to find it is unusable in this application. Can I at least use the Castrol GTX in the cleaning phase? I'm planning on starting this application on Tuesday afternoon so the reason for this post.
I wonder how many marginal results or poor results can be attributed to this recent revelation concerning GTX?
My other question is if my engine (2.9 liter 24 valve I6) holds 5.9 quarts of oil do I put in 5 quarts of oil and the bottle of Auto-RX bringing the total to 5.9. Or do I dump the Auto-RX in 5.9 quarts of new oil? The reason for the question is the instructions say Pour 12 full ounces of Auto-Rx® into your existing oil.
There is a ring on the oil dip stick making note NOT TO exceed the factory recommended amount of oil in the crank case.
