1 million mile goal, no more

what oil have you been running? And what's you're driving conditions like?

edit: also seeing that odometer makes me feel like I have no miles on my 2000, lol. I'm only at 274K miles.

I ran Mobil 1 at first, then switched to AMS oil at 106k. Driving condition 80mile drive to work, 1.5-2hrs drive with traffic.

Sorry, I meant what oil weight do you run. So lots of freeway driving?

Why not just fix the head? I burned a valve at 471K and that’s what I’m going to do. Then when it gets to 500K and beyond it’ll have the original engine. I have a good engine I could swap in but I’m not going to.

I think for him makes a bit of sense because he has a spare motor. Even if he fixes his original motor might be nice to be able to take his time on it with having the spare motor in his car to get him around?

Was it extended performance? I'm just curious since I've dived pretty far into oil so I'm curious to see what people used. Like for instance if it was extended performance, 0w-20 has a slightly higher viscosity at 100C compared to 5w-20, which is kind of counter intuitive. So I've been looking at a lot of their listed stats vs just the group numbers that oil companies put on their labels.

I wonder if you were trying to deal with blow by with oil viscosity if you'd been happier with Amsoil 0w-30 since it's just a little more viscous over Mobil 1 0w-20 when at 100C.
