New Oil

Today was oil change day!

Added a bottle of Seafoam to the warmed up engine and ran it up to 2,500 slowly and drop to idle for about 10 minutes.

Drained the oil.

Got the same small amount of metallic sludge on the drainplug that's been there every change except the first three.  The first three had little trees of metal on the magnet from break-in.

Oil was dark brown as befits 8,390 miles of putt putting.

New Mobil 1 M1-113A filter.

5 qt. Mobil 1 5W-30 Extended Performance and 1 qt. Rislone Engine Treatment added.

I think I will change the oil and filter again 3,000 miles from now, just for spite.

  1. Dude, 8390 on an oil change? I know the oil life monitor might let it go that long but I wouldn't. My workdays went by putting pistons/rings,camshafts and lifters and oil pumps in gen 3 engines.Many schools of thought on oil change intervals but since I fully depreciate my vehicles they never go over 4k.Anyway Precious will love her new lifeblood.Al

    1. I'm increasing the frequency of the changes now just to keep things cleaner.

      I've been astonished at how much cleaner the oil is with the long intervals than the 3k changes with carbs and TBI were.

    2. The newer engines are tighter and burn more cleanly which certainly helps with extending oil life, but I think a lot of it is the oil these days is way better than what we had back in the day. Even the dino oils have better additives now and the formulation of the additives makes a huge difference.

  2. All those loosely controlled hydrocarbons ended up in the oil pan. As a side note lots of those engine repairs I did had heavy oil break down deposits in the pan.(deferred maintenance) Recently I changed the oil pan gasket on my 08 Wrangler.120k and a perfectly clean internal oil pan. I was surprised. I'll be curious what my trucks will look like when the time comes.Al
