    With 256K would it matter? I bet it didint look as bad as you think.

    This is the MSDS for Walmarts oil.....its made by Warren Dist. They manufacture oil for private labels such as WalMart.

    Synthetic oils are great. Been using Mobil 1 in my 96 Tahoe 215K for over a year now. I'll never go back to conventional.

    No the oil life monitor "OLM" is just a computer that calculates multiple things like engine RPM and such. It has nothing to do with the actual oil in the engine. All I do on my vehicles is reset it as I do not go by when using AMSOIL. AMSOIL has been 25,000 mile drain intervals since 1973 when it was the first synthetic oil on the market. Our diesel oils are Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.

    One of the best benefits with AMSOIL is also the fuel milage increase you will get. Some of the best results I get back from my customers are in 4.8L, 5.3L and 6.0L Gm engines. Most of these engines get an average of 2 MPG increase from feedback I am getting.

    I've considered using Amsoil a few times now, but I usually do oil changes without a lot of planning ahead. So, ordering my oil off the internet wouldn't work so well for me since I can't get Amsoil locally. I am running Castrol synthetic in my Avalanche though because it is a lot lower mileage than my last truck and I can justify the cost. I have my spitfire running on Royal Purple, which is crazy expensive around here, but it will only need an oil change once a year (once I replace the oil pan gasket so it stops dumping it on my garage floor). I feel like the oil life monitor goes for a really long time on this truck though in comparison to my last one considering the amount of driving I have done since I got it.
