I just bought an 2002 Infiniti I35 3.5LV6 with 18,000 miles. My buddy talked me into using Amsoil. I bought the air filter, he also sold me: engine flush, 6 quarts of 5w-30 100% synthetic oil, and 2 oil filters.
My question is this, does the synthetic Amsoil actually stay good for 25,000 miles like they claim. Common sense says it sounds like a bunch of BS to me, especially since I live in Arizona and it is dusty. I don't know if I am comfortable waiting 12,500 miles or 6 months before changing just the oil filter and then adding a little more fresh oil to get the oil level correct.
They claim their oil filter can filter better than the average filter and their oil lasts way longer. But how can that be when you are sucking in crap through the air that in return gets in your motor oil. I would think that logically the oil filter would just get clogged up faster if it filtered better. I am confused on all their claims and of course I am ignorant when it comes to motor oil. Please enlighen me if my thinking is off because I really don't know that much and most of the posts on this forum are way over my head anyway.
