So do you have catch cans on your two vehicles? I've been meaning to buy one for the Acadia so I dont have to clean the milkshake gunk out every few weeks.

I have an Elite Catch can on my Camaro but have not gotten around to putting one on the Acadia. The last time I checked the Acadia I got about a teaspoon of oil out of the intake tube. That was with 30k miles on it from new and the first time I checked it. I was lazy up to that point. But my Camaro has a good 2oz of oil in it after 2k miles of driving on it.

Science behind this?

 

I know right.

 

-Burns cleaner

-Is 85% Alcohol and Gas

-15-20% more Consumption (thats why you get less mpg)

-Higher octane ratings allows our Flex Fuel trucks to run more timing. Equals an estimated 25hp/25trq

-Corrosion myth has been proven false on if used on new Flex Fuel vehicles.

 

http://en.wikipedia.org/wiki/E85

Alcohol will vary from 51%-83%. Octane will vary as well. Be advised you can't do a standard rm2 octane rating on alcohol. Some kind of

Alcohol will vary from 51%-83%. Octane will vary as well. Be advised you octane numbers for e85 are largely bogus. "There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual octane engine tests"

We'll it burns better than Dino in these trucks, it does burn more of it, but everyone knows that when they put it in the tank.

I'm not defending Dino vs corn juice or vice versa.

I just know i like running it, and I have seen it appears most like it when they try it in the 14-15 gm trucks.

You know, I might be going back to E85....Yeah I do like the fuel economy of 91, but the truck just seemed to respond so well with E85, not night and day difference, but it just "felt" like it did. Placebo? Possibly..

I really don't think it's the "placebo" effect. I was running E 85 since February. 91 was 40 cents cheaper so I got a tank of 91. Big difference to me. I had to change lanes and went to about half throttle to pass a slow moving car. I got around with room to spare but it definitely didn't respond like it did on E 85. Mileage went up 2 m.p.g. I guess I'll go back to E 85. It'll cost about $10 a week for the way I drive but the extra zip is worth it to me.

Definitely not a placebo effect. The truck has been dynoed to show a significant increase of about 20hp/20trq at the wheels, just by running e85. That is a very good upgrade coming from just using different fuel. You could run 91 and do intake/exhaust and not get those kind of numbers.

With a tune, E-85 vs 93; E-85 definitely runs and pulls better.

 

Canned tune + corn juice = well done tires

 

Yea, that was corny, but if it is available in your area and you are not a corn commie, give it a shot, at least a couple tanks, it's like crack, you'll be addicted.

Ethanol is garbage. Very bad for vehicles. Where I live we use pure gas no ethanol. 87 is all u need.

Not true. E85 is bad for non e85 vehicles. High milage e85 engines are cleaner of carbon buildup than the equivalent engine running gasoline. E85 cleans the system up. E85 is worse for the environment to produce than gas.

all I know is u can't go wrong with pure ethanol free gas. I don't care if my truck is flex fuel. If it's not good for my lawnmower I'm not putting it in a $50k truck. Just my opinion.

Lol you cant compare a carbureted lawnmower to a truck with ECM

Can you explain why ethanol is "garbage" and why it's bad for vehicles?

 

-E85 burns cleaner.

-Makes our trucks produce more horsepower and torque, about 20hp/20trq, at the wheels.

-Cheaper than gas

-Will not corrode fuel lines or tanks. This myth has been busted numerous of times.

Lol ok. We could go on and on about this. I'm not alone on this. I live in Oklahoma and I would say that the majority of people here do not want ethanol in there daily driver.

The only problem with e85 is that it eats up gaskets and fuel lines after a long time but with the e85 option we have upgraded fuel lines, gaskets, fuel pump. E85 is a ton cleaner for the engine

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
