Re: my car is eating to much antifreze
Don't matter on the engine
If it disappearing and not leaking maybe your headgasket is blown
More details?
Is it leaking
Is the oil milky looking
Is there oil in the coolant
Overheat issue
Codes

Re: my car is eating to much antifreze
Probably has air pockets in the coolant system and its just leveling off using coolant from the reservoir.
And its not eating the coolant,more like sipping on it..how fast depends on your vtec usage....

Re: my car is eating to much antifreze
Why would it matter on vtec usage .
And a whole month of filling it up every two days I'm sure that there wouldn't be anymore air in the system
Put a cardboard under the front of the car,
Let it run for 15-20 min
Check the board as to we're the leak is comming from
Front or back of motor
Then inspect hoses and stuff
The coolant is going somewhere
The car isn't drinking it

Re: my car is eating to much antifreze
If it's not leaking under the car and not leaking IN the car (busted heater core which will usually cause a sweet smell), then it's going out the tailpipe and you have a head gasket issue. No way around it.
Ignore what VTEC usage boy said.

Re: my car is eating to much antifreze
When coolant warms up it expands. The expanding liquid has to go somewhere. Once it raises your cooling system pressure high enough to overcome the spring tension in your radiator cap it goes into the overflow.
The opposite happens when you shut the car off and things start to cool down.
Pressure goes down, so now the coolant system is trying to suck water back IN. This is why you have a tube that goes to the bottom of the overflow tank, and why it's important to have coolant in that tank at all times. If you let that tank run dry, the cooling system is going to suck in air, which isn't something you want to have in your cooling system.
This expanding/contracting also helps in working out small air bubbles. They'll just get burped out into the overflow tank, and get replaced with water when the engine cools.

Re: my car is eating to much antifreze
Actually you can have a very small imperfection between the cylinder and a coolant jacket( one or multiple) and you would burn/boil the coolant. Another symptom is the overflow rising, and the systems stays pressurized over night or for a few days...boiling introduces air and supersedes the coolant essentially...overflow rises then doesnt return is another symptom. It's possible if the vehicle is boosted to only introduce compression on high boost strokes or when doing full boost pulls. I have personally had cylinder head gasket failure in this manner and traditional testing will not fail...for example: a combustion tester on the radiator yielded nothing on multiple occasions...would bleed the system one day and three days later back to having air introduced in the system. Why? I pulled the head to find a small section of the viton gasket material pushed into ONE out of hmm I'd say 8-10 coolant jackets surrounding all four cylinders. Meaning 1 out of 40. 😂. But it was enough to occasionally make my s2k jump up one point on the coolant temp scale on the dash. Air pockets around the cylinder can crate very hot areas of both the head and block wreaking havoc on longevity of your build. Paranoia is sometimes your friend!
