Hey all, looking to get some suggestions on what oil weight I should run in my 99 V70 GLT? it gets to about 100+ in the summers and about 30-40°F in the winters. I can’t really seem to decide between 10w30 or 5w40 since I’m not really sure which weight was being used before I bought the car. Brand isn’t an issue as I’m going to stick with liqui moly but some insight would be appreciated. This is my first turbocharged car so I just wanna make sure I’m giving it the right stuff it needs.

Also heres a pic of it with it’s new pegasus rims :D
