Post your latest oil change

Just changed the oil yesterday on the 13 Sonata 2.4L. I used 5qts of M1 EP 5W20 and 1/2 ish qt of m1 EP 5W30. I let the engine drain for 2 hours while i detailed the interior, and the engine took 5.65QTS to fill it back to full mark on dip stick. Prefilled the premium k&n oil filter with more then 1/3 QT 5W30 EP, ran 1/2 qt new oil through engine..

It was a smooth oil change, had about 10K miles/6 months of highway driving on this run of M1 EP 5W20, Will not happen again esp being the 2.4L with direct injected, and timing chain AND being above what hyundai recommends of 7500 miles under normal conditions. The old oil was pretty dark, but did not smell of gas or anything abnormal. I aim for 6 months 6K miles.

Cheers!

What do you use the rislone for, cleaning, preventing sludge, how many ocis did you run it? I bought a concentrated/HM bottle to throw in my nieces 08 Corolla to help with cleaning.

Cleaning aspects and I only ran it one OCI. Have read good reviews on it, ran it for the whole OCI and think it would be a great idea for your Nieces Corolla.

Ps. The Baja is short tripped 85% of the time and hence changing with only 2215 miles on oil/filter.
 
2021 Subaru WRX 2.0 FA20DIT, 952 miles. Drained out factory fill and put in Pennzoil Platinum FS and Subaru Tokyo/Roki filter. I might cut open the old filter (952 mile LOL) and see if there's anything interesting in it.
