Well, with "Global Warming" it may continue to improve for some time, i.e., depending on how far north you are.
Amsoil 5W20 First try

Last summer there was crappy gas being sold in the US that had lower energy content. My car's gas mileage back then was much lower than when I returned to Canada after a road trip.
Wow, some great results....But....If this oil could achieve even a 1 mpg gain over conventional oils, wouldn't the Big 3 be climbing over each other to get these results?? Just wondering....quote:

I purchased a used 2001 Ford Windstar van last July (05) from the Ford dealer. I am the second owner, the first owner purchased new from this same dealer and did all of the regular maintenances at this dealer.
Regular oil changes with Motorcraft 5W20. This van is immaculate (112,000 mile when I purchased it). So for the last year I changed the oil 4 times using the same oil as previous owner.
But having used synthetics since 1989, I changed last week using Amsoil 5W20.
A few days later I went on a business trip that took me a little over 700 miles. When I checked the mpg I could hardly believe it.
The best I had done previously was 23.5 and once 24 mpg highway and usually between 18.5 and 21 town.
But now the worst I have done is 23 city. On the trip I kept getting 28 mpg with the A/C off and cruising 65 mph.
When I used the A/C I got 26 highway, and 24 between city and highway.
I am going to check this closely for the rest of this month (June), and if this keeps up, this van will be getting the Amsoil 5W20 from now on.
Good Day,

This sounds like a more likely scenario.
Well, many years back, Honda sent cars to the EPA for the mileage testing. Oops, they got caught-had Mobil 1 in the engines. Disqualification, since that was not the factory installed oil.
Fleets have shown mileage improvements of 3-5% for decades. Individuals have found anything from zip to over 10%. But then, we all know that is impossible, huh?
Gee, dyno tests show increased horsepower! Wow, that means I can get more zip, but I don't get any better fuel economy. Duh!
Yep, must be the gas, or the weather, or global warming (did you catch the report on core samples from the north pole region which showed evidence of tropical weather?), or a great tail wind-

**** - hasn't happened to them so must not be true!
3-5% is quite a bit more believable than 8-14%. And you're more than welcomed to base your knowledge base on anecdotal evidence.
here's another (anecdotal) 'i saw it!'...
5spd nissan 3.0l v6 4wd switched from whatever it came with fluids to all amsoil at purchase (~35k). saw immediate and consistant 7-10% economy improvement (~2mpg). granted, this was engine (0w-30), tranny, tranfer and two diffs (all 75w-90).
same story, auto mitsubishi 3.5l v6 4wd switched at ~10k.

Sure, for whatever reason, XOM's gas (mainly regular) doesn't give my car as much power as it normally has with other brands like Shell, Sunnoco and Lukoil. My car also runs better on 89 than 87 octane. You would be surprised at the quality variations between grades of gas and different gas stations. Around here, a company did a test of some of the local gas stations and you are not always buying what you should be getting!
My experience with Amsoil going back almost 30 years is that it's common to see a 2%-3% gain from the synthetic engine oil and an additional 1%-2% gain by changing over the transmission and differential to one of their synthetic lubes. So if you do the whole vehicle at the same time and keep careful records, a increase of 3%-5% is very reasonable.
The other factor here is that you can often substitute lower viscosity synthetics for the factory fill. For example, you can run the Series 2000, 0w-30 in place of a 10w-30 or 5w-40 and use the Series 3000, 5w-30 in place of a 15w-40, HDEO. You can also use the 75w-90\80w-90 synthetic gear lubes in place of an 85w-140 in many commercial diff. applications.

A friend of mine put Amsoil 5W20 in his Ford 5.4 pick-up and noticed a pretty good jump in mileage. Enough that he wants to try it in his wife's Ford Escort.
He was running Castrol 10W40 in the winter and 20W50 in the summer for some reason though.

10w40 and 20w50... to 5w20??? Well then no kidding he noticed a jump in mileage
No kidding
, and he claims that it feels like it runs better too.
is this the oil you chose: XLM - XL 5W-20 Synthetic Motor Oil
XLM - XL = ?
XLM - XL = ?
