OE gap is .035"; there ran mid 40's to nearly .050". Apparantly the engine was running fine.

2017 Toyota Tacoma 3.5 V6, 103,665 miles.
Out: dealer fill, work order said Castrol full synthetic 0w20 when I bought the truck 3 months ago.
in: Mobil 1 ESP 0W30. Also installed new metal filter housing, reused OE filter stand pipe and bypass valve.
I used a full bottle of Redline SL-1 in the fuel tank about 500 miles ago and that must have cleaned something out somewhere, because the oil was nasty, and there was dirt/carbon in the filter and filter housing as well.
I did notice the timing cover sweats a little bit from the area they are known to leak from, gonna keep an eye on that...

I’m still on the original spark plugs in my Civic, it’s going to hit 200,000 miles in the next few days
What’s the recommended service interval from Honda?
Today on the Explorer: 104,263 miles, 7,855 mile OCI.
Out: HPL PCMO 5w-30, Ecogard synthetic filter
In: mixture of old Mobil 1 10w-40 HM, 5w-30 HM, a pinch of Liquimoly Top Tec 0w-20, and another Ecogard synthetic filter.
I’ll be cutting the old filter open and post the pics if it’s interesting.

2015 Dodge Grand Caravan, purchased from my local county at 104k. Religious oil changes from the dealer most of the time and a local shop the past few years according to carfax. I did a few repairs and 500 miles later it’s time for a baseline oil change and took a Wix oil sample.
Out, unknown 5w30, Premium Guard filter.
In, Valvoline 0w20 synthetic, Champ XL filter.

It’s 100,000 miles. But with iridium plugs and gentle driving I see no reason why they can’t go way longer. I’m still getting incredibly good fuel economy and the engine idles smoothly so they are still doing their job.
Yes, they might be very hard to remove one day
But I’ve gone this far so I may as well keep going further

Takes me back to when Pennzoil YB was the Holy Grail for cleaning up sludge on BITOG. Before Auto-RX and GC were oil the bomb. Oh yeah, nobody on BITOG ever had sludge. Except back in the day when Auto-RX and Pennzoil YB were very popular here because so many people worried they had sludge.

Did you have a different account back then?

yes. I was away for a few years and forgot my UN and PW. Created a whole new account when the machine didn't find me by email address. Doesn't matter since I seldom posted and I'm sure none of that was worth anyone's time.
Any sparkles found in the oil or filter?
I didn't see anything notable. I posted some pics in the oil filters forum. I looked through maybe 1/3 of the pleats. I saw one small shaving but I think it may have come from the filter being cut open since I had to really squeeze the media out of it past the cut.
