This summer I bought several quarts of Amsoil 10w40 Motorcycle specific oil for just over 4 bucks a quart. At that time, I figured that was by far my best option, since I wanted to stick with MC specific oils and it was about the same price as M1 for cars. So, then a month or two back, I wanted to change my DRZ oil, so I went to the local cycle shop to get a filter. They had Amsoil there, but it was over 7 bucks a quart. Since I only needed two quarts, I decided to just buck up and pay it. Then I went to the local marine store, to get waterproof grease for my swingarm bolt. They had the same oil for about 5 bucks a quart. Argh! So... now since I have decided to strictly use it, I talked to my buddy who is some type of Amsoil preferred customer, and had him price me out a case. He supposedly gets a better deal on it than your average Joe. It came out to be about 7.20 a quart. What the??? He says it must have really went up in price lately. [non MC specific was only about a buck cheaper] So, I guess my point is... how in the heck do they price this stuff? The pricing scale must totally depend on volume buying? How can it fluctuate from 4 bucks to over 7 bucks? I'm having my bro go check the place I bought it for 4 bucks... if its still that cheap I'm buying at least a case of it.
