So this report might make a few people upset. Reason being is that this oil was in my car for around 3 years. This car is a weekend car if you can even call it that. I think in the last 2 years I've done 500 miles. It stays parked inside at my office and just doesn't get driven much. With that said I've made a conscious effort to drive it more recently. This M1 0w40 is the old formula by the way not the new FS stuff. Had a Purolator Pure One filter on it. Car is stock with the exception of a K&N drop in filter, Predator tune, and Mishimoto radiator ( I had two replacements fail at the crappy plastic endcaps and said no more) I wait for the car to get up to operating temperature before getting on it. I would say 90% of those miles are city and the other 10% highway. No track time but I do get on it frequently. I think it looks pretty good for how old the oil is. Only item that looks a little elevated is iron but I hear these LSx motors tend to shed some. Like to hear your thoughts on this. Oil that went in was Castrol 0w40 with a M1 filter.
