I was online looking for grease reviews and couldn't find any. I know this seems really anal but if I'm going to the trouble,.... and the bigger part of the job is labor,..... and its only a few dollars difference between one grease cartridge and another, why not use the best or at least something really good. I'd at least like to have the knowledge that I'm not injecting something that is beneath normal standards. Anyone know where I can find some objective reviews? I don't necessarily subscribe to the notion that just because its Redline or Royal Purple its better because they cost more,...although those products may very well be. Thanks in advance.
