I was gassing up the S today with non-ethanol and an old truck from the forties pulled up to the pump next to me. I asked the owner if he was filling up with non-ethanol and he said no that an old school mechanic had told him it is not necessary on the really old cars just on the newer stuff. Didn’t make sense to me I asked him if he puts non-ethanol in it before he stores it and he said he does but doesn’t use it during the driving season.
“The ethanol debate is endless. Especially when it comes to storage. It can cause accelerated rust in your tank OR it can help prevent rust from forming in your tank. So the answer is both. Ethanol is hydroscopic, which means it absorbs water. So technically, that means there will be a higher percentage of water molecules in your tank. But according to the latest tests, the ethanol in your tank won’t just reach out and grab moisture from the air even in a vented fuel tank. It is more likely to just absorb the moisture that forms inside your tank from condensation which results from temperature and humidity swings. So maybe the ethanol is really saving your tank from rusting by pulling off the exposed tank walls. But then the debate gets even more complicated. Should you store your car with a tank almost full so that very little metal inside the tank is exposed to air but there is a lot of ethanol pulling in the moisture? Or should you store I with as little gas as possible to avoid any water absorption that could cause drivability issues. My conclusion is do whatever works for you. Bottom line is some water will enter your fuel system. It is more important to keep your car stored in a proper environment and used regularly.”
As for myself, I have always stored all my cars with a full tank and never worried about ethanol.
"Nearly all of the gasoline sold in the United States contains 10 percent ethanol, which can safely be used in all of today's gasoline-burning cars and trucks." (From http://www.ucsusa.org/) The operative word is "today's." Ethanol is a cleaner burning fuel than gasoline. It is created from bio-mass, especially corn. Arguments rage about the true environmental impact of growing corn to create ethanol versus drawing crude oil from wells and then refining it. But for now, ethanol is here to stay. Modern cars are designed to use this newer fuel.
Some say our MGs are not. They claim ethanol enhanced gasoline can wreak havoc with our MG fuel systems. Here's what one respected MG tech said, "E10 causes our fuel systems to corrode; SU and Stromberg brass metering needles turn green when lying unused. Some have complained that earlier gasoline tank sealers have lifted off in sheets, clogging the fuel pickup at the bottom of the tank (therefore starving the engine for fuel). This E10 gasohol boils at a very low temperature. We hear from MG owners much more now about hot hard restarts. In some southern climates, running an MGC is all but impossible without great modification. And, MG mpg (miles per gallon) suffers a bit as alcohol doesn't carry the same energy per volume as gasoline."
I've never experienced any of those issues and I have never heard of any of my MG buddies having those issues but we all drive ours which may be the key.
I was just bouncing around the internet reading different threads about ethanol and like your thread said Dave opinions are all over the place as well as facts.
Maybe it's just me but what is wrong with the Lexus styling dept?
man that gill is so damn ugly.
at least the white nose isn't as bad... but the predator's nose is yuck.
Lexus has been doing that for years, others are following suit. I've read that a lot of it is for the Chinese market where the big grill is looked upon very favorably. Dunno if it's true or not, but the grill on the LX570 is what stopped me from getting one in 2019.
^^^ That's why I still have a pre-facelift GS. It's no beauty queen but the current spindle grill looks horrible on non-F-Sport models with its horizontal bars filling that huge maw. I MAYBE could live with the lattice grill on an F-Sport. But I would always have to approach the car from the rear.
