I have seen an increase in oil pressure during the cleaning phase of the AutoRX treatment. I'm only 800 miles in and the oil is dark already. I see 5-7 psi higher oil pressure while the oil is still cold but only ~2psi when the oil is hot. I have 2 5/8" mechanical oil pressure and oil temperature gauges so I get a pretty acurate indication of what is going on. I'm not sure if I can stand to leave the oil in till 1500 at the rate it's going. I know everyone is going to tell me the increase in oil pressure is because of the oil passages being cleaned, but I know thats not the case. The inside of this engine is spotless. I had the valve covers off before the treatment and everything is very clean.
The engine is ford 302 with a mild cam and some headwork. It only has ~35k on it, but is 17 years old. I'm running the RX to try to soften the rearmain seal and stop a minor leak, not for the cleaning. The oil has been changed about every 1500-2500 miles because that is all I put on it in a year. The oil sees sustained 240 degrees on the highway. Could this and the RX cause the oil oxidize faster?
Thanks
