Last oil was Castrol Edge 5w 30 HM. Previous 2 were M1 EP HM 5 30Did the jug say "Triple Action" on it? What was the previous oil you used before this?

I usually put the pellets gm recommends.By the way, use Dexcool with Bar's Stop Leak when you refill the cooling system. Do NOT put the stop leak in the reservoir, but in the lower radiator hose only.
Just protecting. Saw old t stat....i looked worn. Changed 4 years ago. Will change again in another 4.The real question here is why is the thermostat being changed.
If you are experiencing overheat problems, it's likely NOT the thermostat.
Northstar engines were susceptible to head gasket failure, but RARELY did they fail in a way that would allow water into the oil. The common failure showed up as engine overheat due to exhaust gasses accumulating in the cooling system.
If you are having overheat issues, make sure there is full flow from the small rubber hose that comes from the top of the throttle body, and goes to the coolant reservoir. This was there to insure no air is in the cooling system.
If it is plugged, REMOVE the hollow bolt at the throttle body and clean it out. DO NOT use air to blow the stoppage back into the engine, it must be removed.
If you have full flow, and it spurts air periodically while the engine is running, you have a head gasket leak.
I take extremely good care of it......and i ask questions at the bobistheoilguy forums so my ignorance doesn't ruin my car.Mostly pre-2000 Northstars and those are mostly all dead by now. I'm surprised it's not leaking and burning oil fast enough to stay clean.
Sounds like the oil is loaded with contaminants too fine for the filter to trap. That can't be a good thing. Just because the particles are too small for the filter to trap, doesn't mean they won't cause wear. The oil life monitor is a gimmick used by the marketing department to sell you on it being a low maintenance car. It doesn't analyze the oil and measure the level of contaminants. It uses a program that takes into account many variables such as number of cold starts or idling time to estimate how worn out the oil is. It can't detect excessive blowby or gasoline dilution from sticking injectors. 3,000 mile OCIs were the gold standard up until 30 or 40 years ago, yet the engines are still basically the same. Only the ancillary components are updated.Mechanic says oil needs to be.changed because it's dark. OLM says 63% remaining life....oil was changed 2200 miles ago in January.
It's a design thing, not lack of care. My 00 Deville was sold with almost 190k, still drove and looked great. Oil burning an leaking for probably 150k of those miles. Even dealer fixes were temporary.I take extremely good care of it......and i ask questions at the bobistheoilguy forums so my ignorance doesn't ruin my car.
The only thing running rich is the mechanic's wallet by upselling an oil change.Has it been running excessively rich or anything?
Is this on the dipstick or when drained? My oil always looks golden colored on the dipstick, then when drain into drain pan it’s blackMy oil is still a nice light gold, still transparent when I'm down to 7% oil life....4100 miles in 3 months. Lots of starts and lots of idle time, but also lots of highway.
If it's getting dark by 63% it's probably either cleaning out deposits, or has blowby.
Mechanic isn't asking to change it, he knows I do my own oil changes (that and tire rotations is about all I do myself).....

On the dipstick and in my hands when I spill it. It's black in the pan because the pan is black and full of junk residue in the bottom.Is this on the dipstick or when drained? My oil always looks golden colored on the dipstick, then when drain into drain pan it’s black
You guys realize there is basically no profit in the oil change itself right?The only thing running rich is the mechanic's wallet by upselling an oil change.
Seems like an excellent reason. I mean, if when going to the bathroom you notice it's red.......well I better not go there.Color alone seems like an odd reason.
Ok, when I do my next change I will use a new clean aluminum foil pan and see if there is a differenceOn the dipstick and in my hands when I spill it. It's black in the pan because the pan is black and full of junk residue in the bottom.
He just changed the oil! What is wrong with you guys?!Seems like an excellent reason. I mean, if when going to the bathroom you notice it's red.......well I better not go there.![]()
Sorry.Seems like an excellent reason. I mean, if when going to the bathroom you notice it's red.......well I better not go there.![]()
Same thing.I usually put the pellets gm recommends.
