Wow. 7000 miles on conventional oil is impressive.

Not all daredevils wear capes.Wow. 7000 miles on conventional oil is impressive.
Is there a correlation to molybdenum content as well tied to this data?4. Lead wear per mile shows a trend (albeit weak) of increasing wear per mile as the oil age grows.
When I bought my 2004 V8 4Runner brand new from the dealer I did lots of reading on BITOG on the 4.7 motor. From what I remember Chevron Supreme 5W30 was the go to oil back then and was the oil a lot of people were using for their 4.7 extended oil change intervals. It just goes to show how low wearing these motors are.Wow. 7000 miles on conventional oil is impressive.
Change it at a year regardless of mileage. Too cheap not to.With this whole work from home thing going on, I’m far from my planned 8k mile OCI and I’ve had the same oil in there for a year already. This is by far the longest I’ve gone without an oil change. Will I be the first test case for leaving in the same engine oil for over a year (maybe 2 at this rate)? I’m tempted to send a sample off to see how it’s holding up so far.

Could’ve been better2000 Land Cruiser
1. Stalled while completely submerged approx. 70,000 miles ago. Engine removed, cleaned, dried, & reassembled. No damage
2. Mobil 1 Extended Performance 5W/30 w/ M1-102 filter
3. I try for 5k intervals but sometimes it ends up being 7,500; you can see my first sample was actually 10k

Psh, you're fine. Go look at my 99's reports. Way higher and still ran great for years before I sold it.This one is kind of concerning....iron and copper is high. Bearing wear.
It's embarrassing but this oil change may have went 15k miles between changes instead of the 7k I told them it was. I realized that after I sent the sample off. I had somehow forgot to change my oil on the LX during all the other stuff I was doing on it. Hopefully I haven't shortened the engines life too much..I really wanna get to 300kView attachment 2711599
I had been doing a good amount of mixed city driving and some wheeling trips during those miles so maybe that added to it. I have been going back and forth about what mileage I changed it at last. I swear I had changed it twice since I bought it at 173k,....but I can't remember. I really have to get better at documenting it. Normally, I just use my trip meter, but I guess when I disconnected the battery if reset it? or maybe my wife did it I don't know.Psh, you're fine. Go look at my 99's reports.

You're approaching my 99 levels, but still well below. Shouldn't be too worried about that yet.Here is my latest
If this continues to play out, I'm guessing that the brake controller that was installed is an indicator of my truck's prior service history. I asked the PO about towing and got this back:
Yes, I did tow infrequently, maybe once every other year I towed a sailboat on a tandem axle trailer with electric brakes, total weight 6,000 lbs, 1,200 miles round trip over a week. Truck made that trip maybe six times. This was a pretty flat trip topography wise, we would go north through Indiana or Illinois depending upon the lake we were racing on. The point being no big hills or mountains, mostly flat. Outside of that occasional trip no towing of significance, in distance or weight.

Slight difference though is that I am at 174k miles. You were into the high 200k, right?You're approaching my 99 levels, but still well below. Shouldn't be too worried about that yet.
