I have a 2019 tahoe and there is a sticker inside the duel door that says gas or e85 but I'm unsure if it can take it I need help.

 

Welcome to the forum. It means it's a FlexFuel vehicle and can use either. Be aware that E85 will give you worse mpg.

 

Indeed so! It's cheaper than gasoline for a reason.

 

Not trying to hijack the thread, but can someone explain what the various “E##” numbers actually mean, and what we can use in our Flex Fuel trucks? For example, does E85 mean the fuel is 85% ethanol, or 85% gas? I’ve seen variants on the these numbers and find it confusing.

I have never used E-gas and have always used just regular gas, but sometimes I find the E-fuels significantly cheaper traveling in other states and it might save some $$ on those longer trips. Wouldn’t use it all the time, but occasionally when $$ can be tight.

Thanks!

 

Welcome to Chevrolet Forum,fraziwil000!

 

E-85 is 85% Ethanol and 15 % gasoline. That way no one can get drunk on E-85. LOL!!

But all joking aside BIG CORN want to sell Ethanol made from corn, just like sugar/sucrose is now made from HFCS, not beet or cane sugar.

 

Thanks for clarifying. Now I get it. The “E” is the percentage of ethanol, not gasoline.
