Hey all. I drove home from a regular oil change and didn't notice anything unusual but next day saw oil level was a little high (at about the R in "OPERATING RANGE" on dipstick, see picture). Service invoice says 6qt went in. Took a short drive, pressure seemed higher than normal (about 50psi), slowly dropped to around 25psi steady as truck warmed up. Should I be worried, try to drain some out? THANK YOU!

You had this done at an oil change shop?? Why should you get your hands dirty and possible make a huge mess in you driveway. Take it back and make them fix it.

UPDATE: Took about 0.7qt out the top. Level now in range at top of crosshatch. No obvious issues. Oil pressure is about 50psi right after startup.

After warmup pressure is 20psi at idle.

and steady 40psi at highway cruise.

Is this normal? Honestly never paid this much attention to oil pressures before.
