Loud Whine after Oil change

Mitco39 · 08-08-2013, 09:50 AM

Has anyone had any issues with using Mobil oil filters? I am running a FI'd car that right before the oil change was running fine with no noise. Went for a oil change (5W-30 Mobil) which was the exact same oil that was in the car. The only difference was I had a FRAM filter on it. Swapped that out to a equivalent Mobil filter and now just after getting on the boost I will get a loud whine that will stay untill the car comes down under about 3500rpms, then stop.

It wont start whining unless I boost hard. For example I can take it up to redline slowly and have no noise at all. Kind of leads me to believe that something in that Mobil filter is causing a flow restriction in the car.

Just curious if anyone has heard or has had any think like this happen (on FI'd or non FI'd cars).

Also the oil pressure did not change significantly from oil change to oil change. Going to go out and throw a Fram back on there today and go from there.

Thanks

Mitch
