Many have suggested that Redline oil is best used as an 'oil additive' to a regular fill of oil, as opposed to straight up. We have seen some good UOA's with that combo many years ago.
I'm bringing back the idea, but this time with their new 'powersports' line of oils - they boast having an ester base, 2200ppm of Zn, and over 400ppm moly. Lots of grades - 10W-30, 0W-40,...right up to 10W-60.
Rough calculations have that if you added 1 quart to a 4-quart fill of 0W-20, you'd get a 0W-30 ester-blend with close to 1000ppm Zn, which isn't excessive. Pretty cool.
This is certainly an interesting idea.... I'm going to try this.. I just purchased / ordered a single quart of 5W20 Redline Synthetic Oil for my 2017 Jeep Patriot and plan on adding this single quart to my usual STP full Synthetic at my next OCI ... I'll be subbing one quart of the STP SYN with the single quart of Redline.... Interesting thing though is that after purchasing the Redline qt, I went to the Redline website and it indicated that their 5w20 is NOT a match for my 2017 Patriot... odd as 5W20 is what my owner's manual indicates is required and it's also all Ive used since buying it...
