I Think Installing the Catch Can Broke Something!

[Lunentucker]

I swear my MPG has gone up 1.5 or 2 since I installed the thing.
I was running errands this morning and made several aggressive full throttle two lane passes.
When I got back in town I had the thought that I likely killed my good average I had going on this last fill up, so I toggled in and was very pleasantly surprised.
AFAIK, we're still on winter blend here too.

I would kill for 19mpg… barely breaking 17.5ish on my 50+ mile round trip on the highway at 70mph.

What brand of catch can did you get? Thinking of adding one to my JT.

we are still on winter blend here in VA? Damn VA needs to hurry up swap out.

I think someone said it's like that until late this month or early next.

My truck has never seen 15mpg. Ever! I am on 37" with 5.13 gears.

hello is there any reason one can not pour the oil back into the engine? or does it have an elevated level of gas vapor contamination?

Funny that you posted this today. My last fill-up on Friday has so far pushed my average from 17.8 to 19.2 after driving 170 miles. I thought at first that maybe the gas station accidently put 92 octane in the 87 tank.

I wouldn't.
I had to dilute this with solvent and wipe it out of the bottom of the can.

yowza! the oil in the first video looks virtually new compared to your video. thanks

That's what was left behind after I poured the oil from the first video out. That gunk wouldn't pour out.

The U.S. Environmental Protection Agency (EPA) defines April to June as the “transition season” for fuel production. Refineries lead this transition and switch over to summer-blend production in March and April.

Gasoline blends used in the summer months are different than the blends used in the winter. In the winter, fuels have a higher Reid vapor pressure, meaning they evaporate more easily and allow cars to start in colder weather. In the warm summer months, these evaporative attributes would lead to increased emissions and the formation of smog.

However, because of various state or regional requirements, 14 different fuel specifications are required for the summer months. Refineries must produce enough fuel for each area to ensure there are no supply shortages, and that can complicate the production and distribution of fuels.

Summer-blend fuel is also more expensive to make than winter-blend fuel. First, the production process takes longer and, second, the overall yield of gasoline per barrel of oil is lower. These complexities add as much as 15 cents per gallon to the cost to produce these higher-grade fuels.

May-June: Deadlines for Terminals and Retailers
The May 1 compliance deadline for terminals to fully purge their systems of winter-blend fuels is considered one of the biggest factors in seasonal price increases.

Interesting, I may have to investigate this further. On a recent trip, Colorado Springs to Grand Junction I saw 20.1 mpg driving US50 out and 17.6 mpg driving I70 back. The main difference is speed limit and elevation, but I ran 87 octane vs 85 which is considered regular here. '21 Mojave with 4.10 gears, 35" AT tires and an AEV spacer lift.
