It would be a very narrow reason to use redline plus biotech, like I wouldnt recommend that 99% of the time, mixing two ester products. Literally the only timer I would even try this is if redline is in and tick is still present,, Then I might try it only to see if then the tick would be gone.
The recommended amount is for engines that run normally, since we tend to run biotech for hemi tick the correct dose would be up to 32 ounces. I like the 15-16 ounce amount for most cases, if by chance 32 ounces is needed to kill tick assuming group 3 oil In 7 quart sump, I'm gonna call that generally safe. In the case you run 32 ounces, I'd add one quart of your oil at a higher weight so viscosity doesn't thin. Two considerations, using biotech in good running hemi versus hemi tick engine. The best way to use biotech is use less and see if you get the desirable result, but you can adjust as needed. Also, the science and forum experience suggests sometimes the relief is not immediate, so give lesser amount time before you adjust.
