My mom wanted to know this and I didn't know so I figured I'd ask on here? Which vehicles can use the new E85 gas? Is it all vehicles or is it just some vehicles?

 

Only some vehicles with the 5.3 engine. I believe you will see "E85" on the RPO code list in the glove box if the vehicle is flex-fuel. Check to see if the gas cap is green...it's an E85 vehicle if it is.

 

o ok, well i doubt she can use it, she drives a 98 tahoe

 

i think most vehicles CAN use it but is not advisable

i think the only differnece between e85 and nonE85 engines is some fuel hoses because the ethanol in the fuel causes the standard hoses to decompose or break down

if used for long peroid of time it would break down fuel hoses

NOT ADVISABLE

 

so its just hte hoses. the actual engine is the same for both the L59 and LM7 5.3 liters?

 

NO!!!! do not run E85 in a non-E85 vehicle it will run like $HIT the computer has to learn the octane rating and adjust accordingly.... yes the hos are diffrent but the fuel system and settingsre way diffrent!!!

 

yeah im with grumpy... if you run E85 for long periods of time it will screw stuff up... my truck is a 5.3 flex fuel but i have not ran it in it. and about the gas cap mine is not greem

 

Don't worry, the engine won't stay together long enough to damage the hoses.
