After hearing many good things about AMSoil, I decided to give it a try.
I just flush and change to their 5W-30 oil & Filter (the 25,000 miles) type.
I have an 03 Infiniti G35.
My question is that, how long should I wait to change my oil, though they said that their oil & filters are good up to 25,000 miles or 1 year?
I drive around 80 miles daily. I'm thinking of changing it every 10K miles? Is it okay or should I change it earlier?
