I just got a 2011 cadillac cts4 with 202k miles def a lot of crud in the oil system but runs smooth should i do an oil system clean when i change the oil? is it worth it or will it lead to problems?
I would just do an oil+filter change, then another maybe 1000 miles down the road.
i did have a problem with the oil pressure sensor reading zero and the check engine light on but fixed that and the light went away that's when i noticed the crude when i fixed the sensor the ride became a tiny bit rougher still smooth though and it could just be paranoia because of the miles but i felt ie i lost a tiny bit of power too, thats why i was wondering if i should do the cleaner too since i was going to change the oil and filter anyway, what do you guys think still leave it alone?
Safer to gently clean it with a short-miles oil change or two than introduce chemical cleaners.
I would worry about doing that. I would leave good enough alone.
With that age and mileage, the oil cleaners might do more harm than good. It might ruin the rubber seals and you end up having more issues. Listen to @chucktobias.

I was thinking ab using the chemical 505 oil and gas cleaner in my car. But a cleaner engine can also be achieved w/ quicker oil changes. This obviously won’t help the gas system. Clean engine, happy wife
