Burla, thanks for the info. I read up a bit and am wondering why redline versus Royal purple for oil?
If you choose RP go for it many guys like it.
Speaking from a perspective of dealing with hemi tick, Redline has pao/ester base with the most aw/ep additives.
When we started the syn thread Royal Purple took out the moly, something they used to use in high amounts like 180ppm when oil guys loved that, then many years later they put moly back, but at average levels 60-80ppm. RP also uses dyes and group 3 base oils, with "some" esters maybe = synerlac. So research uoa's and see the difference, the largest are moly and zinc and the base oils dont show on you but redline is openly committed to pao/ester base oils. So what gives you the best chance at keeping hemi tick away? less or more additives made to deal with those conditions? What makes sense more or less of group 4/5 saturated base oils?
The argument "for" Royal Purple would be likely better gas mileage, formula more friendly for catalytic convertors, and maybe their moly and less group 4/5 will still get the job done. I do believe RP should be in the mix for hemi tick, my problem would be how do you know moly level? The best answer would be RP street line, that has remained consistently high like that 170ppm range. If you had hemi tick and RP killed the tick, it looks like a better choice then redline? sure why not. But, Redline is the hemi tick nuke, maybe many of us are lazy on testing new things, it is a real PITA to change oils and still have tick tick tick, when you can just nuke it. Redline is built like a brick**** house, pretty decent choice for a hemi that can benefit from all of that. It certainly isn't the best choice for modern engines, but maybe a good choice for a hemi.
Mind you this is for their RP engine oil only, there is a laundry list against them on gear and tranny oils.
Like said above a vid would help.
