the directions say to replace the oil filter b4 you add the flush,but my question is wont all the oil come out or does it stay in the oil pan?

 

The oil filter is located above the oil pan, so the only oil you will lose is what's in the filter itself. Make sure to change the filter again after the flush has been run through and before the fresh oil is added.

 

so i need to buy 3 filters for this?? can u give me a step by step please,im confused.

 

should jus need 2 buy 2 more. from wat ive heard, u switch the oil filter, ad the amsoil to the oil and run the car for 30 (sitting still at idle for 30 min) then drain oil, switch filter and refill. sry if i missin anything, but i think thats it!

 

Yep, that's it. Buy the cheapest filter you can find to run the flush through. It's only going to be on there for a 1/2 hour at most. Use the good filter before you add the fresh oil.
