Bad bottle design & too viscus
If you drive a semi or have some other type of vehicle that has a wide-mouthed fuel access then you won't have a problem pouring this but if you drive a regular vehicle, you're screwed. The bottle is a flat-nose which wouldn't normally be that big of a deal but the fluid is very thick so trying to transfer to a container to pour it into my Jeep is a slow & potentially messy problem. While pouring it, I can't even tell if any is coming out due to how thick it is & it too, if I'm not careful, makes a mess as I'm taking the bottle out. Just like the fuel optimizer, I don't seen any gains like what's listed on the bottle compared to before so won't be buying this again either
