I have a 5 gallon tub of 600W oil. If you are an antique car collector, then this is for you. You already know the oil goes for over $10 a quart. I only used less than one gallon before I sold my cars. I will sell the other 4.5 gallons,or 22 quarts for only $50. That is only about $2.00 a quart. If you need this stuff or know someone that does, I just need to uload it to clean out my garage. Oh, yes, it is Mobil, I think they are pretty much the only company that supplies it anymore. I am in Aptos, just south of Santa Cruz, but I frequently travel to San Jose and Monterey. If you want it but do not want to travel, I could just bring it to you on a trip if you are not in a hurry.
