    Compressor OCI with synthetic oil

    Oneeye one would think so. But my boss errs on the cheap and fast side of things. His theory would probably be if I need to check the oil then I can just change the oil at the same time. Really I was blown away that he didn't fight me on using synthetic oil, but that was due to the possibility...

    Compressor OCI with synthetic oil

    5w-30 multi car suggestion

    Hi, I am new to the forum and would like your thoughts on an oil selection. I use the same oil for both of my vehicles. I am looking at moving away from Amsoil. Their oil is getting costly, and I don't know if the price is justified (my last purchase averaged $7.21 a quart). Their MLM tactics...
