Originally posted by Donald: Amsoil is one of the cheapest oils (in cost, not quality) if you go through the math for the extended oil change at 25K miles. Amsoil also warranties the engine if its damaged by their oil/filter changing the oil at 25K.
quote:Thank you for getting this thread back on-topic. Amsoil is way behind Castrol and most other off-the-shelf synthetics in total gallons sold, even Wally's Super Tech brand. MLM may make a good profit for a few in the limited distribution chain, but you cant beat the mass market for building sales volume.
Originally posted by Dick in Falls Church: My guess is that AMSOIL is probably second in total gallonage of synthetics, well behind Mobil 1.

With my wife's new job and losing a member of her car pool, the dino is going to see more and more miles, and every other week the car will be getting a good warm up twice a day. I went looking at the UOA's and didn't see many 12mo/25K posts. Can I really do this? Where are the numbers?
Originally posted by Click: "widely regarded as myth" "very few folks run 25000 miles on a change" Both those statements are totally false. Not sure if you have talked to more than 10 people to come up with them or not. Amsoils customers and dealers have been using the ONCE a year (not twice in your statement, perhaps a typo?) changes, since 1973 in a proper running engine. There is NO question that the 25000 interval works or they wouldnt have been doing it for over 30 years right? snip....
quote:I disagree. I had a bad UOA due to the Power Foam use and had to change the oil early. I wrote Amsoil and requested replacement oil, filter and oil analysis. A few days later, a box with 6 qts oil, filter and the oil analysis kit arrived at my door. No cost. I think that you may have to have your "ducks in a row" to get help, but try to get anything ($) out of Mobil. (Remember what happened in Alaska a few years ago???) Cheers, Doug
Originally posted by Last_Z: As for Amsoil's warranty, you better hope you'll never need it. I suspect it would be easier to fly to Mars than getting a nickel from Amsoil.
Originally posted by buster: I agree and then you have to ask yourself, am I getting the extra performance for $4 difference in cost? Right now-NO! GC beats the **** out of S2k 0w-30 and costs 50% less.
