Looking for some creative idea
Hey everyone,
I've had my Volvo S60 2015 2.0L for a year now. Recently got some maintenance done: new spark plugs, first coil, 0W30 oil, and engine air filter—all OEM.
Since then, fuel consumption has shot up by about 40%, even when the car's parked. Went to a local Volvo dealership again for an oil change, checked everything with a diagnostic PC—no issues found. They also replaced the spark plugs with original ones, changed the engine oil, and mentioned something about an "oil cup" (not sure what that is).
Now it's burning through fuel like crazy—about 5 km per liter—which is really pricey where I am.
Any ideas what might be causing this? Thanks in advance!
