Almost 2 months ago I posted about losing 75% of my dipstick in a 200mile drive. Did some research and came up with a JiffyLube receipt of last oil change and it said they had put 5w-30 in my car. Realized this and got it changed and refilled with some 5w-40. Dipstick showed it was right at max when refilled and I've been driving no problem since... Until yesterday. 2,000 miles later and my oil light is on and dipstick is below minimum. Very inconstant loss of oil and I can't figure it out. Installed an oil catch can not too long ago and it's barely caught anything - leading me to believe it's not PCV related. Been burning oil for over a year with this car and none of the spark plugs are fouling.

Here's the link to last thread: https://www.crossfireforum.org/forum...ease-help.html
Would love any input on what could be happening. Desperate to figure out this problem and ensure my engine is nice and healthy.


Also those codes from last thread also led to my right cat failing, causing car to sound like a ricer and stink up the cabin.
