we've been doing 'extended' drains of 5k miles (extended given her very severe service), and getting excellent results. Given that its started full cold 6x a day, never heats up except once in a while on the weekend, and is only used for short trips, the car runs and UOAs EXCELLENT!
This is a chrysler 2.0L 4cyl from a plymouth breeze, but it appears that M1 will be an excellent oil for most chrysler engines. Id highly suggest it. Give M1 EP a try if youre really thinking of stretching it out, though im sure regular SM M1 will do it just fine as well. EP may be a little better in the cleaning department though.
