MPG to the moon! '06 LX470

[NolaNomad]

Wow- never thought I'd see mpg this high. Presumably the result of new Fuel pump ,Evap charcoal can, Fuel filter and a bottle and a half of 44k + full tank of non ethanol 91 octane.. geeze I'm so broke right now..

But what about the extra gallons of 87 octane you could've bought with the price difference of 91 octane. Are their any savings there?.....if reducing fuel cost is your goal.

I was told to run clean 91 while doing the 44k fuel system cleaner

What was the MPG prior to the work done?

Was up and down been 12.2- 14 mpg

Make sure to change the oil after running the entire tank of 44K.

After I cycle a full tank of gas through first correct? I was told if the oil is fresh to just change filter?

non-ethanol fuel will definitely contribute to higher fuel economy, but given the price difference (around me) I'm not sure if the increased economy actually totals any real savings.

 

[excessive]

how did you get a new charcoal canister ?

 

[Petertn45]

Nice job. Were you having any particular problems or just doing preventative maintenance? How many miles do you have?

Started with a stall/no start issue- boiling fuel. I'm at 250k miles. So I just replaced as many components as I could myself. Including a few relays. What's yours looking like?

What's your MPG and milage

2006LX 164k miles, have ko2s
Mpg about 11-12. Need to fix a small exhaust leak but have replaced one aftermarket cat due to failure and all o2 sensors, coils

Onboard mileage computers (especially 20+ year old computers) are notoriously inaccurate - overstating the MPG.

Short of having a closed course and scales, the most accurate method is still the "Fill - Drive - Fill - Calculate" method.

What's your MPG and milage

right now, zero MPG... long answer short, I have no (accurate) idea, I can only go off relative changes as my odometer seems to be off by ~10%, but I was calculating 10-11mpg before the tree damage, at 95% in-town driving. The best I've ever calculated was a couple of summers ago in CO mountains on the highway with a calculated 17.8 mpg. current odo is like 232k, and last repairs (that would impact MPG) before the tree included new headers to replace the cracked manifolds, retorque spark plugs and replace all 8 coils (7 were cracked).

my only point on E0 is that the energy density is like +4% vs E10 blend (normal 10% ethanol), but near me the cost is around +25% vs regular 87. by itself, I'd be surprised to see a +25% bump in economy.

once I get mine back on the road legally I should have all my tune-up stuff done and I'd be interested to do a new baseline mpg and compare it to a tank of E0 and see how much difference there is. I know on old carbureted bikes it makes a huge difference.

Previous owner put on slightly larger tires, so I don't trust my odo, either.
I suppose I could drive up and down the interstate between mile markers with a gas station at one end.

I always run 91 octane that's what the manual says

I always just calculate off the trip meter, reset at refueling. Like I said, it's all relative. From full, I was lucky to hit 200 mi on the trip meter to low light, which usually seems to be 21-22 gal to full. Figuring I'm about 9-10% off, that still puts me right around 10 mpg... however, I'm a bit on the heavy side (had roof top tent on, front steel bumper with winch, rear steel bumper with 5th wheel swing out), and always keep ECT on and have a heavy foot, along with the mitigating factors I mentioned previously (cracked coils, cracked exhaust manifold that was getting worse)

Word. I'm getting lots of "feedback" from folks asking why I run91 if. Midgrade will give better mpg

Speed apps for your phone are pretty accurate. Get up to speed (the higher the more accurate your result will be) and set your cruise control. Divide the number in the app by the number on your speedo and you’ll have your exact correction ratio.

I did this on a cross country road trip and the screen was always within .5 or less within accuracy
