Pls help

I’m worried my car is dying. Its been drinking gas more lately, when driving sometimes the car will get stuck in fourth gear so I would have to cut the car off and on to get it to shift properly and on top of that oil is showing in my coolant reservoir along with the car saying low oil or pull off on the next gas station. I’m low on ideas of it all but especially of why oil is in my coolant reservoir because I and my father had replaced the coolant housing not too long ago along with the gasket. if anyone can pls help

If your car's head gasket is busted then coolant is mixing with engine oil.

I'd take it to a mechanic to look and see what they say. If that's the case you better sell it to carmax while it's running.

The car us sick, but I doubt it is actually dying. If you want to try to fix it yourself, a compression check will show if it’s a blown head gasket. Once that is done, you can proceed from there. Head gasket replacement itself is about 6/10 difficulty. If you do not have at least some experience and a torque wrench, then this is probably a job for an independent shop.

It may not necessarily be a head gasket. Oil filter housing, transmission cooler on radiator, etc are other sources of passing water into oil. Take it to an experienced shop for diagnosis.

But don't wait if you keep driving it, it can result in catastrophic engine failure
