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.

Well here's the results of two oil changes with the Valvoline restore and protect. 193,224 miles, diving in to my neighbors 2012 L94, deleting AFM. I'm satisfied the Valvoline did some good. I'm sold on it Note the plugs we tapped into the oil towers.

And here's what the oil pan looked like when we dropped it. Keep in mind this engine only had two oil changes with the Valvoline..... You can clearly see it was even working on cleaning the pan in the area where a lot of oil flowed down from the front. The very bottom of the sump was very clean aluminum, no sludge. Never seen that even on an LS with 90,000 miles.

Do you think the loosened sludge could gum up other internal areas? Like oil passages, push rods oil pump, oil pump pick up screen etc? Also what was the oil change intervals? I change mine every 2500-3000 miles. I do that on all of my vehicles.

 

[rdezs]

Oil change interval was between 4 and 5000 miles for the life of the vehicle. The the pickup screen was clean, as was the screen under the oil pressure sending unit. Haven't pulled off the oil pump yet, but I want to look in the relief valve to see if there's anything there. But so far it seems to have pretty much dissolved any deposits, instead of just breaking them loose. Timing cover and oil pump, etc coming off tomorrow with pictures.

Doing this with my neighbor on his vehicle, he wants to learn so we have to coordinate our schedules. He did say he's been running 5W-30 full synthetic, multiple brands over the years. Running the standard AC Delco filters. He paid to have his transmission fluid and filter changed around 100,000 miles..... Omg, think we'll drop that pan and take a look when we're all done with the engine. He said the 6L80 has never missed a beat.

while I've seen that nice orangeish red in just about everything engine I've ever seen inside of with any good amount of miles/hours on it. I used to consider that a happy well maintained engine and was happy to see it vs any build up or black gunk. I considered them totally different things.

but I can't argue that it's nice to see it clean that up even if I don't really see it as something leading to an issue. not seeing much down side to running this oil over anything else right now.

I hhope they don't double the price or something.

Am I missing something here? Where's your 'before' picture?
