Hi all,
I remember reading on a different thread about how Red Line "cleanses" extra copper from the system - I was wondering how true this actually is. I left Red Line Oil 5w30 in 2 of my cars (evo, mini) for 1 year. Usually they are flushed every few months (racing). However, after leaving them in the engine for a full year, it seems they are actually coming out with more copper.
Is it correct that it isn't "true" wear? Both vehicles have been running RL 5w30 for multiple changes before this, which makes me think leaving this oil in the system does indeed corrode copper, not "pull extra" off of the bearings etc. It was mentioned that after 1 flush of this, the copper wear is supposed to go away, but I've been running it for quite some time now. Would be odd for both cars, after using a 1 year OCI, would show copper wear.
If you look at the previous runs, you'll notice overall low copper. The intervals and use (1-3k miles, autocross) have been the same, but the copper wear spiked after leaving the RL5w30 in the car for 1 year.
