Lubegard BioTech can't prevent lifter failure. It's a really good cleaner if you have a dirty engine, but that's about it. The reason for that is because Lubegard uses a Moly-Phosphorus compound, not Moly-Sulfur. So it doesn't work as part of the oil, but rather competes with the oil for the surface. Bonding additives to the base oil is complicated chemistry. So complicated in fact, that each manufacturer has their own proprietary technology for doing it. Castrol uses a PAO molecule IIRC to do it, and they have a patent on it.
Highly friction-modified oil like PUP SRT 0W-40 helps cut lifter wear. So does Castrol EDGE 0W-40 and EDGE 0W-40 C3/Dexos 2, but that's my own little experiment, so disregard it. RedLine Oil is better than PUP but if you choose to go that route then keep some PUP receipts for warranty purposes. Otherwise, PUP is good stuff.
I'm not at all opposed to spending the money on Red Line. I will readily admit that I'm not a chemist or oil expert. I guess I'm just a bit confused as to whether the PuP with Lubegard will protect as well as the Red Line and at what mileage I should start using the Lubegard. From what I've read previously, it sounds like RL and Lubegard is the way to go. I just don't want to buy oil that I'm not going to use (PuP receipts) nor flirt with warranty issues if something goes south. Not that I think the dealership that I use would actually demand oil receipts, but it's better to be safe than sorry these days.
