Will gas mileage increase

Yes, I drive a 2020 Toyota Corolla SE and I race the engine a lot. I use this every time I do an oil change. My mileage is at 32k atm, but some gasolines I use aren't always the best. When I don't use Lucas my rpm when going on freeway speeds they sit at around 1,800 but when I use Lucas they drop down to about 1,000 rpm and it saves a lot of gas. Then again I keep up to date with the maintenance and I've been using Lucas since I got the car and this is my daily.

Would keeping this in the car in hot Texas heat be an issue?

OF COARCE ITS A DANGEROUS ISSUE !! Storing any flamable liquid in a car is very dangerouse , especially a hot car !! you put yourself at risk of combustion from the heat & also combustion if you get in a accident !! buy a tiny bottle of lucas fuel additive , its about 5.5 oz.s !! fill that up and insulate it in trunk to keep it cool . then when you fill up ? you will have a bottle ready to put in your tank !! instead of hauling around a gallon of the stuff .

Whats difference between this and the fuel treatment 5 oz

Their is no difference other than the packaging

Will it help remove P0420 code?

2 bottles of Lucas oil, one gas refill apart, helped with my P0420 Code on Infiniti QX60 engine light. With the 2nd bottle, the light was gone. It worked like a charm. I will continue to keep the fuel tank clean moving forward. Tip : don't wait for the fuel tank to be completely empty before you refill.
