to around 90 and start driving really easy under 2k. Warms the car up reeellly quick. And about the oil weight i noticed that i'm burning more oil than i used to during the summer, my dad says it's condensation but i don't think it's condensation when u see exhaust smoke cover your car and glide down the front windshield. It was an on and off thing during the summer, but it's getting more frequent lately.
