I know that you don't judge oil by its looks, but I just changed the oil on my 1995 Blazer with a 4.3L Vortec.
Old Oil:
3.3L of Esso XD3
1.0L of Mobil1 5w20
Maintanence Dose of AutoRX: Couple Oz or so.
Miles on oil: ~4000miles
Date Oil Changed: Early February
Reason Oil Changed: Leaking rad leaking small amounts of coolant into the oil cooler.
New Oil:
Engine Oil: Esso XD3 Synthetic 0w30
Oil Filter: Valvoline Maxlife
Changed the oil two days ago a couple weird things happened.
1.) I put in the 4.3Ls needed for the oil change and it seemed to have overfilled it? Weird.... The truck was on ramps like any other time and it seemed to have filled the drain pan just like it always does but the oil but it was 0.5L overfilled....
2.) Took it for a 50 mile drive just thinking that the oil needed to circulate and fill in the void in the oil system but it was still the same level.
3.) Seeing the filter is mounted behind the front bumper horizontally, I just loosened the oil filter to drain off a half of a liter and tightened it back up and ran the engine for 3 mintes to reprime the filter and the system again.
4.) Now I took the oil and poured it into a glass measuring cup and shined a bright light through it just for fun. NOT ONE RAY OF LIGHT COULD GO THROUGH IT. COMPLETELY OPAQUE AND DARKER THAN MIDNIGHT.
5.) Emptied and cleaner the measuring cup and poured fresh oil in for a reference and the light came straight through bright with no obstructions.
Now my question is, after 50 miles could have this excellent oil done that much cleaning and suspended that much solids to make it that opaque?
And even if 0.5L of old oil was still in the pan hence the overfill, should it have affected the clarity that much in this little of time?
Also noticed some bits of hair strands of metal on the drain plug for the first time, but that could have been the AutoRX doing its job.
Your comments are welcome and please be civil, I just want to gain information and I know clarity is not the end-all-be-all of engine oil.
