Post your latest oil change

2018 Mazda 6 2.5l
3,128 miles on factory fill
IN: QSFS 0W-20 and Mazda filter

Did you notice any fuel dilution in that Skyactiv engine or any oil usage? Is it a mostly sever usage?
The oil did have a slight smell of fuel, but was not above the fill line. This car is a family members and is heavily short-tripped. I am recommending that they change the oil every six months going forward.

Yes that's my plan after I get the first 5K miles on mine. Mine has just stayed on the full mark. I'm thinking I should get a UOA just to see where I'm at in the area of fuel dilution!
 
2021 Ford Fiesta ST
20,100km

Out: Fuchs 5W-20 dealer bulk oil, Ford filter
In: Liqui Moly Special Tec AA 5W-20 (WSS-M2C960-A1), Ford filter

Only just bought this car, so will be interesting to see how this oil holds up. I plan on six month, 7500km OCIs which is likely overkill but that’s just fine with me. Nice big ~6.1L sump which is nice for a little 1.5L three cylinder turbo
