Valvoline Restore & Protect experiment

[Foggy]

it is in no way a scam. it is 100 plus octane race gas at the local gas station for less than 93 piss water petrol.

the 6.2 engines love it, it also cleans the top of pistons. now gm didn't spend the money to install a physical sensor on these trucks and trys to do the math off the reg o2 sensors which is mostly a failure. but that's not e85's fault.


just because you don't own a car that can take full advantage of e85, I hate seeing people shit on it. anyone with boost and a flex fuel sensor it's a god send.now if we would. remove the tariff on it and just sell it at the price Brazil sells it to us we would be set.

Definitely need a real alcohol sensor to run E85 (which is usually e70)..
These virtual fuel sensors that just use the O2's are so bad... I always reset
them whenever I'm doing work as they are usually very wrong
I was thinking about getting a real alch sensor on mine so I could run E every
once in a while to clean things up a bit. But overall I'm not a huge fan of ethanol,
but the turbo guys love it due to it's octane rating

I don’t use it much during the colder months but May to September I try to run 2 or 3 tankfuls.
Some say it might be more beneficial to run them back to back so I may give 2 a try and see.

Of course the benefit is cumulative, as it'd likely be with, say, Valvoline restore & Protect.
Also, the benefit during the winter months would be less, as it's only E51 during the winter, not really E85.

I bet '25% lower MpG with E85' is an oversimplification.
I wonder what if ethanol's city MpG penalty is worse or better than ethanol's highway MpG penalty.

I used to be a field service guy and drove a service truck a lot, so I filled up my tank many times a week. Most had v-8 engines of all makes. I experimented with using E85. Usually... because the mileage with E85 was less, my rule of thumb was the E85 had to be at least 50 cents a gallon less to break even, dollar/mile. Most of the time I just used regular 10% because most stations didn't offer E85 at the time. Cant say I noticed any noticeable performance changes.
