i have been struggling for some time now as to which oil i want to use in my truck. the two finalists so far are amsoil and mobil one delvac, but the amsoil is fairly difficult to get and somewhat controversial, while the delvac is very hard to find in my area and extremely expensive when i can find it (app. $30 per gal. ) today i was at a trusted diesel injection service business buying some stanadyne, when they informed me that they strongly suggest schaeffer oil, specifically the super 7000 synthetic. they claim they have had tremendous success with this oil, and i can buy it here for about $60 for 5 gallons. my problem is that i've never even heard of this oil,
and am not overly excited about using a product in my pride and joy that i'm not familiar with. anyone out there familiar with this product or can give me any advice on it?
