1. The 3000 miles oil change should be history.
You can change engine oil every 10000 miles under
normal driving condition. So this product is no
better then normal engine oil. Buy a car with
engine oil life monitor, you will know it.
2. It is not recommemted to put any additive into
engine oil, tranny fluid, etc., not to mention
this is not a name brand. If you don't believe me.
Go to any dealer, and tell them that you are going
to use this in your new car. I bet they will
tell your new car worranty would be gone.
my 2 cents.
