I have VW99 Passat 1.8L Turbo, automatic with 170K on it.
My car shop changed engine oil yesterday with 4 QTS of Mobile 5W40. Now, when I check my dipstick today, on level surface, the oil level is way too high on dipstick kink [the cross-hatched mark]. I run the engine, shut it off, and let it set for 3 min, but still the level is too high above the Mark. It wets the dipstick almost till the top of its Head.It was reading High when I first checked it, this morning, before starting my car.
It seems the oil is 'overfilled' or showing over filled; and the engine is about to throw it out from ‘filler cap’ where Dipstick goes in the engine. I saw him using 4 cans 1 QTS oil, which I bought, into my car.
They did change the ‘oil filter’ at the same time?
Now, my car looses power while driving. When I accelerated from a stop/light, car slows down or limps. The car suffered a sudden loss of power.It runs awful for about a mile but smoothed out after acceleration.It feels like the car is running out of gas for a few seconds, then all of a sudden it kicks in. The car still drives ok though - No error messages/warnings on dash,CEL, no smoke, no hissing. I actually don't see engine oil thrown out or leaking though.
I don’t know if the shop drained the ‘intercooler’ while changing the oil, also I know nothing about its importance to my power loss issue.
The net search manual/states "The engine oil, above the level, can be drawn into the crankcase ventilation system, and enter the atmosphere via the exhaust system". But it does says about damaging the engine/car.
Should I be worried about the damage to the engine? Can someone please help advising me what to do?
The shop is closed till Tuesday, and I have to drive the car during this weekend, but I am nervous. I don’t have much clue about oil change, more than the grades of oil.
