As many guys have mentioned... you are being over charged . I have a suggestion , Not in any way promoting Amsoil just using it as a example... You can get on there web and join for 20 bucks and be a "preferred customer" and purchase there high quality products at a great savings... I use there OW-40 in my apex for 8.90 per quart and have been using there oils in most everything I own. 25,000 miles on my apex! and its runs like the day I bought it....the 20 bucks is a small investment for a high quality product that if you read up on will save you money in the long run especially in your cars and trucks! and there IS other good choices, This oil thing can be widely opinionated so Iam just trying to help.
