It was added at the 1:5 concentration. I got the oil control valve(OCV) pulled yesterday afternoon screens were not plugged. Installed a new OCV while I was it was out. Also replaced the OCV solenoid and camshaft sensor as well while I was at the timing cover area, so all related parts are new. Reset code and code came back on after a couple short drives.
After reading the All data diagnostic aids last night "The oil condition has a major impact on the camshaft actuator system", 3/4 of these problems can be attributed to oil issues according to the all data troubleshooting. "advise customer oil change may be required". Seems to all point to "dirty or degraded oil" which I get.
Got up early this AM and as much as it pained me to waste the EC

, I dumped the oil with 35+ miles on it and dumped the as much oil from filter and re-used as it only had 30+ miles from a fresh OC. So far after 3 drives and several ignition cycles no code.
The 3 other cars are doing fine on the EC(one is closing in on 1K miles, other two are closing in on the 500 mile marks), is this engine just overly sensitive?, Overpaid $156 in parts from the local dealer (RA would have been 1/2 but they are out of stock) and it could have been as simple as wrong oil

. I find it hard to believe that a mechanical part is designed to be this sensitive to oil given the wide range of viscosity ranges oil goes through just based on temperature alone.
My question could the properties of esters potentially cause this? The only other variable was I used a Chevron Supreme 5w-30 SP (not dexos for the original change since it was going to be a 2K run anyway), and used RGT 5w-30 SN this time around. Do I run this for a bit then experiment with another quart of EC? Spec is 5w-30 DEXOS.
