Hi,
I was looking for some info. from amsoil.com when I found two types of 2017 Tahoe engines. What is the difference between them? And, how can I know which one is mine?

One engine can use E85 gas and the other can't.

You can tell by VIN. Here's one way to decode your VIN:

The above chart didn’t work for a couple people. It works for my engine/vin however.

I thought the horsepower was 355 in 2017?

the rating is dictated by the fuel selection...the flex motors have the higher rating when running the E85.

Easiest way to tell : If our gas cap is yellow you have a flex fuel vehicle.

nope...I do not have a gas cap at all...just a push through flap.
