Oil life question

I was just going to come back and say the exact same thing...beat me to it

Thinks it’s worth it opposed to just changing it every 3k?

I would get it tested just to see what it says even as a baseline if you have never had one done

a test result would look like this, my sample had water contamination so they didn't check for fuel but was still fine

Really nervous to open my oil cap…

just pull it off and flip it over, should be clean as a whistle, but if you are only driving short distances I have seen them look gooey, all you can really do about that is just go drive it around, take a road trip now and then, Take the wife out to dinner out of town or something.....

So it isn’t necessarily a bad sign

no not unless you are loosing coolant then you have to decide how to proceed from there. the wifes 04 had a small internal leak and I used some bluedevil on it and it worked great. those kinds of snake oil things only work sometimes.
when I treated hers I made absolutely sure it wasn't leaking anywhere else and it even passed a pressure test and a combustion leak test so the leak was pretty small.

You did this yourself? If push came to shove I’d just take it to the shop. Got money I save just for this damn Tahoe haha.

ya you can rent the pressure tester from most auto part stores like auto zone it's free they just take a deposit and then when you return the tool they give you the deposit back, same with the combustion tester but generally you have to buy the fluid seperate a bottle of it was like $10 and would do several test.
the bluedevil is not exactly cheap it was around $50-60 for the required amount, you have to follow the directions otherwise you are just wasting your money
it gets poured in a COLD top radiator/hose, then you go drive it around for like 30 minutes and it's done. It activates with heat, so pouring it in a hot engine/coolant is not going to work. the general consensus on the bluedevil was to use the one you leave in, they also make one that you use and then drain the coolant and start over with fresh coolant. I left the permanent one in for about a month then flushed everything. That stopped the leak for good.
the bluedevil is only for head/block leaks, not for anything else unless they sell something marketed otherwise.
I did that versus spending a lot more time and money to tear it down and have the heads checked, engine had around 230k on it at the time
the caveats to that are that it "could" clog up stuff inside. when it activates it turns into a glassy looking material, I had spilled a little on the engine and aftwards i could see how it changed and became a solid, it was then stuck to the metal but I could chip it off with my fingernail. I guess that's how it seals a leak just puts a layer over it.

Interesting.

Would you say I could rule out the coolant thing than if I I’m not experiencing loss of coolant or overheating? Or could it still be a concern with the oil life and oil itself etc. I will check that cap asap
