True! I continue to be impressed with the GS 450h in all regards - fuel efficiency, performance, smoothness of the hybrid operation, reliability, handling, comforts, features and build quality.

I had a Lexus tech tell me he attended a Lexus hybrid training meeting where a talking point was made about the GS 450h receiving extra scrutiny in terms of build quality, to the extent that special focus even went into making sure interior sounds were eliminated with extra deadening materials. The GS 450h is definitely quite a special car.

 

My 2013 specifically says no E15

 

Oh damn.. Looks like u'll be trading in first before me then.

 

I'm in the market actually but not going to pay these insane prices. It's been 9+ wonderful years with the GS. I'm torn between a fun sporty car or a more utilitarian vehicle such as a truck or SUV. I don't drive much so gas prices don't concern me just yet.

 

My 2014 gas cap, so I think e15 is ok.

 

I think mine looks like that too. Wonder why 2013 says no E15. The engine is the same.

 

That's interesting. I think Lexus must have changed their minds after 2013. We're all using the same engines. My 2013 says Up to E10 only.

 

Shoot.. Y'all are making me doubt myself. Let me go to the garage and see.

 

Okay, just checked and mine says up to E15, same as jkeller's. My 2015 Prius is the same and probably the ES too.

Maybe cars from 2014+ can accept E15?

 

The GS has been using the same engine for like what? 15+ years now. I think someone at Toyota finally got around to testing E15.

 

Mine says no to E20-E85.

 

Sort of, but remember in 2016 it switched from the 2GR-FSE to the 2GR-FKS. Lots in common between the two motors, but significant differences too.

 

 

My 2007 GS350 with a 2GR-FSE engine has a gas cap that does not have any Ethanol restrictions on it. The 2007 Owner's Manual states under the Fuels Specification page that Lexus allows 10% ethanol blending.

My personal preference is to avoid gasoline with any ethanol added since ethanol attracts moisture, and any water in a fuel system can cause real problems. I would be opposed to increasing the allowable % to move to 15%. Iowa corn growers gonna love this change.

 

The QuikTime stations here in the Austin area offer no ethanol gas, but the octane is only 90 and it costs as much or a few cents more than 93 premium E10
