    Very true..thinking about it, oil needs a change. Running 0/50 at moment. Before doing so, I'll assess temps again over next week and then make an "executive decision" to dump and go back to old...ratio of coolant/ water is currently 40/60.

    You shouldn't really go over 50% of the coolant concentrate in any engine, that's for sure. But, I think that the problem is on your side (engine just too old, or the ratio is incorrect) not within the G13 coolant.
    I know that you came to the conclusion that the G13 is at fault right from the start, but the faults in the cars aren't what we want them to be.

    Correct. Too much coolant is not good for cooling. My coolant to water mixture is at 40% coolant. Drove around yesterday and today in these cooler days and still higher in both water and oil temp. I cracked it....let car cool down and dumped g13. I flushed out system for over an hour and went back to my valvoline zerex g05 coolant, let fan fan run x4 to let system bleed properly and then took for a good drive....low and behold, average oil temp between 94c-96c again. Went for a run on the highway and hit 100c tops. Coolant temp with constant drive and airflow between 80c - 84c.
    For some reason unbeknownst to me, g13 just doesn't agree with my ride. Not saying it won't be great in others, but have come to the conclusion not in mine. Based on my experience with it, I personally wouldn't recommend it. Merry Xmas all and many thanks for the post, Much appreciated..
