In the spring I made a decision to change out all my cars oils to Amsoil, oil and filters, and just change them once a year. Well, I got cold feet with the car I take to the race track and changed it after 5 events (07 350Z and yes it has a dual pass oil cooler so temps are around 250F on track on a 100F day).
Now to the issue....I have my DD van which is a 2013 Chrysler T&C with 296,000 miles on it. It has the Amsoil SS 5w-20 in it. It burned a over a quart of it already in the 6000 miles I drove it so far. I threw in a quart of 10W-30 Amsoil SS to top it off as thats the last of the SS oil i had left. Figured that was better than topping off with a different brand. It always has had oil consumption but this is more than normal. I am probably going to put another 6-8k miles on it over the winter. Do their extended OCIs even apply to an engine with this high of miles? I am considering just dumping the stuff and changing the oil twice a year on everything with PUP since I get it from WalMart for under $25 a jug. Maybe I am not cut out for extended OCIs? Anyways, Is running a 10k+ OCI on a Pentastar with nearly 300K miles on it a good idea or is this dumb?
