Has anyone ever run Amsoil in their cars?
Doing as much commuting as I have been, I saw their 25,000mi oil change interval with their Signature series, and I saw Mobil 1's 20,000mi or 1 year oil as well.
However, if you go on their website and put in your car, only Amsoil shows their Signature series for our cars. Mobil 1 doesn't suggest it.
Realistically, I pay about $45-$50 every 5,000mi (7 weeks) for a new oil and filter. At 10,000mi, the cost between Amsoil and Mobil 1 would break even for me with regular 5,000mi intervals and oil changes. At 15,000mi is when I start saving money.
I do 120mi/day 95% of it highway, and I typically don't warm the car up beyond a minute or two.
Not looking to start a good or bad oil thread, just looking to see if anyone has had an analysis done on our cars yet with Amsoil or Mobil 1 extended performance.
