Recently did an oil change. About 3 weeks later, I noticed my oil pressure gauge reading low.. About .1 bar at idle, 1 bar while driving.

I thought I must have installed a bad oil filter..

I did an engine flush, switched to synthetic, new oil filter..

Now Im up to .75bar at idle, 2 bar driving.

Classic oil pressure sending unit symptoms.....

Changed it out yesterday with no change.. I am getting good oil pressure all the way to the top of my engine. I can physically see the oil squirting out of the oiler. More throttle = more oil..

I doubt I have a mechanical issue, but I dont know what to check next.

Any advice?
