Hello Sammies, yes the motor will run a little richer when adding the oil, but you will be able to lean down the motor harder to get back your rpms; you should not have to change gears at all.

The KLOTZ will not break down until 555 degrees and if it does it is only breaking down 15.7cst which is very minimal from when the oil is fresh and new, so no worries. I hope you don't run your engines upove 555, lol.

You will get more smoke then normal but that is letting you know that is getting lubricant. Don’t get me wrong just because it smokes it does not mean your engine cannot overheat because it will, if it is not tuned correctly.

I see you added 10 mil that is only going to change the percent ½ to ¾ of percent if that, I could be wrong, but I am not a math wizard so I cannot see the change that you’re talking about, but that’s ok the more info racers put out, is how we all learn. We all are going to think and feel different when we test, so I understand your concerns. . 30- 50mil might change to maybe 2 to 3 percent, I will try to figure that out today and get back with you, because I have never figured that out.

Now if your already runny 12 – 16 percent and adding 50 or 60 mil, then yes the oil contents is high and can change things but will not hurt the engine. I only add lubricant when I am racing in high heat and humidity.

But in the other hand you can run the KLOTZ oil as low as 37 degrees.

Hope I hit on some of the question you’re asking and I will try to get back with percentage later today.
Thanks Billy
