What kind of MPG can I expect?

Recommended Posts

Hi Guys,

I just bought a 1986 20.5' Mini-Cruiser with automatic transmission and 4 cylinders.  How much mpg should I expect.  I've been driving it around town for a few days now.  I've gone 46 miles and I've lost a quarter of a tank.  I'm getting a little worried.  I've read that the needle will go down past E and I should carry some extra gas, great idea.  What Mpg are you guys getting?

Thanks!

11-14 MPG with a proper tuneup, at normal Toy house speeds.. 65-70 mph cruising will result in 8-11 MPG

These figures rise substantially when a for sale sign is installed.

If his gauge is about the same as mine he's already getting around 13 mpg driving around town. The only way your going to know highway mileage is to hit the road. Speed is the killer of mileage. I try to stay at just under 60 for the best mileage. Any faster and I can watch it drop

I've had two Minicruisers.  Not that I think the brand matters much.  My 1988 19 foot Minicruiser on a Toyota with a 2.4 EFI engine and auto-trans gets a best highway "average" of 14.2 MPG.  NOTE.  That is not a best "one time tank fill" like some people like to post. I never drive faster then 60 MPH.  My 1984 17 foot Minicruiser on a Datsun with a 2.4 carbed engine and 5 speed manual trans got a best average of 15.5 MPG.  By the way, do not let the lengths I posted throw you off.  My 1988 that was called a "19 footer" may be the same as 1986 that was called a "20.5 footer." Not sure how and when they measure for those ads.

I did a trip from Wisconsin through the Rockies 18 months ago.  We covered 4000 miles and averaged 13.6 mpg.  This included going from WI, MN, SD, WY, MT, ND, and back home so we traveled through a variety of topography.  Our best milage was 15 with a tailwind and the worst was 12.5 with me driving.  

 

My daughter drove one tank of gas and had her foot on the floor the whole time while I took a nap.  We got 9.5 on that tank.  She was not allowed to drive the RV after that.  She had to drive my wife's car pulling the pop-up that our kids were using.

I have a 1988 21 foot Toyota Dolphin, 22RE engine, A43D automatic transmission. I typically drive 55 MPH in third running at the top of the torque curve. I will use the overdrive in situations where i have favorable wind conditions but still no faster than 60 MPH. I average 13.3 to 13.7 MPG.

Finally an accurate description of mileage! So far in my travels around Ohio (Ohio is not flat farm country like many people believe. S. Ohio is the foothills of the Appalachian mountains) I've averaged 14.2 mpgs fully loaded! Learning to drive Grannie from other members I now downshift before the engine bogs down and use OD down hills and on flats. Guess I'm on par with others!

When I first picked up our rig we were averaging high teens - that was with just me and two kids (3 & 7 at the time) - no gear, no extra food, no full water tank etc.  Now with the whole family we have been avging mid teens.  That's 5 of us in the camper, lots of gear, 4 bikes + bike trailer, full water tank, and no shortage of food!!  We stick to 60/65 on hwys and keep to the speed limit on 2ndary rds.  I've been keeping track on Fuelly:

How can you get such better mileage than the rest of us especially driving that fast??

I assume that message was aimed at me.
I'm guessing that our 319 is a smaller rig, and prob weighs several hundred lbs less than most others.  It's only 20ft long, bumper to bumper.  I keep meaning to weigh it, one of these days we will stop at a weigh station --- does one just stop at the stations along the highway?  Are they public?

Mine is 20.5'. I'm sorry no offense to you but I just don't buy that kind of mileage especially having a rig as loaded as yours and driving over 60 mph. I've done Everything to try and improve my mileage by even 1 mpg! Never drive over 57mph. Downshift when necessary. OD on when going downhill and on flats. I've replaced all wiring and vacuum hoses. Plugs, distributor cap and rotor. K& N air filter.Complete tuneup with valve adjustment, all new brakes, fuel filter, etc. My rig  only has 37K miles on her. Oh well your rig must be magic LOL!

This is the 2nd time I've shared my mpg on this forum and someone has questioned my numbers.  I really don't think it's all that amazing what I am getting, folks are always advertising better than that in sale flyers - obviously some of those numbers are exaggerated, but generally these rigs are renowned for efficiency.  If I tried to hypermile I think I could stick to high teens all the time - but with a coach full of kids I usually try to get from pt A to B as quickly as possible!!  That's not to say I am gunning it nonstop, but I certainly would drive a bit easier if it were just my wife and I.  
Maybe your rig has a chevy 454 under the hood and you just don't know it yet :P

Of course when someone is selling on Craigslist the mpgs are dramatically increased. None get high teens unless its a little Chinook, maybe a shortie or driving down hill, possibly a stick shift. Do you have a 22RE Auto? People question because what your stating is unbelievable. I've got the same engine as yours! Have fun. No disrespect just don't believe it but maybe others will.

Looks exactly like my Granville Derek! Manufacturers gas mileage estimates usually aren't known to be very accurate LOL!

Looks like a independent magazine review - or you think it's a paid advertisement?  Either way, 19.5mpg seems magical to me even :sorcerer:

That was back in the day when gas was really gas. Mileage for all of us would have been better. No ethanol. Also Maine has done quite a bit to limit ethanol in fuel. Maybe cleaner gas explains some of his improved mileage.

Perhaps the shape of the Winnebagos offers a fuel economy benefit compared to others.

Do you know what the pickup truck mileage was shown at for that year, engine and transmission? I had a Toy pickup with automatic from around that era that might have got those numbers. I also remember lots of bitching about advertised mileage vs actual mpg. 

EDIT! Why ask Derek,  I have Google.       https://www.fueleconomy.gov/feg/bymodel/1986_Toyota_Truck.shtml

I had a SR5 truck with the 22R and a stick shift long bed and got around 20 mpg but that was without a 5000 lb on its back!

I doubt you drove it at a cruising speed of 55mph on level ground. :)

Wasn't the US national speed limit 55 back in the day? So all the mpg's being looked at were with a national speed of 55?
