I read, tcw3 must be used correctly in dosage toomuch kills your mileage, too little wont do anything at all.
Right, you want to add it to the gas. But the ratio is related to miles and only indirectly to gallons of fuel. So, the MMO folks suggest a quart per 1000 miles. For many smallish 4-cylinder engined vehicles, that might work out to about 1/3 quart (11 fluid ounces) per 12 gallon fuel fill-up, assuming your tank holds about 12 gallons and you can go 333 miles on a tank of gas. You will have to plug in your own numbers, which will probably be different.
As for tcw3, I have no idea. It is sometimes used as an upper cylinder lubricant, but you will have to search the forums and find out how others have used it. I would imagine the dosage rate is much less than when used in 2-cycle engines.
Typically MMO is added to gas at a rate of 4 ounces/10 gallons of gas. TCW3 is usually used at half that dose. Those are good starting points and many people tweak it from there, usually lowering the amount slightly.
OTOH MMO Inverse Oilers are usually set up to use 1 qt./1,000 miles.
