Subject: Re: Does anyone use synthetic oils?

Here is my $.02: you can't even spell Mobil 1, much less figure out how much it costs. Mobil 1 is about $4.10 per US quart at Wal-Mart, the world's largest retailer. Several times a year, Wal-Mart sells Mobil 1 in 5-quart containers for $17.88 ($3.58 per quart). Per the Amsoil web site, their synthetics costs from $5.20 - $8.10 per quart (depending on quality and viscosity). > In my area Mobile 1 is about $0.10 cheaper than what Amsoil 7500 is.
