1. What kind of vehicle you have
2016 wrx, FA20DIT
2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well
5w30 API SN resource conserving or ILSAC GL-5
3. Where you live
New York
4. How you drive (easy? hard? fast? slow?)
Easy on daily commutes which are local roads, stop and go traffic (borderline short trip).
Hard on weekends. Never tracked or auto crossed, but would not mind the protection.
5. What your daily drive is like (short trips? long trips? city? highway?)
See above. Mostly local traffic. Spirited on the weekends.
6. Whether your car has any known problems
No problems per se, but FA20DIT’s are known for their propensity for heavy intake valve carbon deposits and pretty bad fuel dilution.
First oil report on PUP 5w30. Sheared with only 2k mi of light driving...
Dilemma here is:
Switch to non RC 5w30 like Mobil 1 esp?
Or move up to 5w40? If so which one? My biggest concerns are intake valve build up and higher oil temps.
FYI, Im modded, stage 2: engine tune for full exhaust, tgv/egr deletes, air oil separator installed, aftermarket intercooler. Pushing 300whp/325wtq.
