Post your latest oil or filter purchase

I won't be posting picture of all I bought. Preparing to do lots of services on my Audi A3 quattro and 2019 Escape. First all the Ford stuff at 54k miles. Full synthetic Castrol Edge 5w20, oil filter, rear diff using GM LS gear oil. Rien fluid for Haldex, Pennzoil LV for trans, Motorcraft 75w85 updated fluid for the PTU (instead of the owners manual fluid) and a Hengst air filter. The PTU fluid change was per a service update which makes the PTU last longer and reduces running temps. Few people are aware of that trouble area in most Escapes. So far I did the air filter and rear diff last night. The Audi is a 2008 due for Haldex service using VW fluid (compatible with Rien), Haldex filter, plug, drain, refill plugs, DCT fluid for trans, DSG filter, GM LS fluid also for the rear diff and new NGK plugs. Oddly I've found out due to my tune level I need to regap these plugs a little tighter to 030 0r 032 from the pregap of .036. Live and learn. In case you guys notice I'm using a limited slip 75w90 in two open differentials its because the LS additive is redundant but the fluid is better at cold temperatures. It was originally sold for Corvette usage. I am still looking to buy a fluid for the Audi front diff that needs a 75w90 gear oil thats just GL-4 rated no GL+/GL-4/GL-5 allowed. The additive packages can cause issues and few people realize that front diff has an electric lock up so I've been told an MT-90 is the standard to keep things working correctly there. Its narrowed my choices but having a low capacity, I won't break the bank.
BTW, I worked in dealerships for over 4 decades and did 13 makes. I research all compatibilities and have multiple drain and fill devices to prevent cross-contamination.

Almost forgot I have rear sway links for the Audi, a new thermostat, thermostat housing , seals, coolant neck, temp sensor, coolant tee and G-13 coolant that is in the plan before summer. I better get busy.
Found out I need to research farther on Haldex or Ford rear disconnect fluid 75w for the RDU on the Escape. AI may have been wrong.
 
Just purchased a 12 pack of Amsoil 10W-30 small engine oil for the generator. I finally broke it in for 8 hours. Unfortunately, I won't have the oil until later next week assuming no delay due to the storm. So, for now I'll probably use more of the Pennzoil 10W-30 conventional. I still have most of the 5qt jug left.
