Are these the same ads that say "a/c just needs a recharge" ?

But seriously, how long have you had this thing? Is it a 21 footer?

Common I'm not that naive. I've had the thing for 3 years and with all the work done on it it doens't get any better gas milage now that it did then.

I even have an aquaintance that gets an average of 18+ MPG with exsactly the same setup only a year newer and manual. Rear end ratio's are fixed for each application so there wouldn't be any signicant difference unless someone has messed with it.

The catalytic converter would be the only thing that might be significant but the torque and power off the line is impressive for a 4 banger so I don't think thats the problem.

I dunno--I'm stumped

 

Hey just found your post and I am in the same boat as you. I purchased a 1988 Toyota Odyssey 21 foot motorhome with 22RE automatic. People I bought it from said it got 14-17 MPG, however I get 11. I had a full tune-up at the dealership and the injectors cleaned, now my mileage is: 11.

This is frustrating because fuel economy was the principle reason I purchased this motorhome (in addition to reliability).

What I find strange is I get about 11 mpg no matter what the driving conditions are. I think I got it up to 12 or 13 on a long stretch of freeway that was almost all downhill, I hardly touched the gas.

Another thing I found strange was that even coming down the steep mountain slopes on the freeway I hardly ever had to even touch the brake. It seems odd that wind resistance alone would slow me down that much. This, along with the poor MPG, makes me wonder if my brakes could be hanging up. I would think though the dealership would have noticed this when they went through the vehicle.

That is my next step to check out the brakes, don't know if it could help you or not but do let me know if you find any solutions, as you said it just doesn't make sense...

 

I had the same responcs comming through the mountains to. Sometimes thw wind would even slow me down comming down a grade. I would stop ever so once in a while and feel the hubs to see if they were hot but they weren't. I had new brakes, lines and rear bearings put on to see if that would help but I still get the same MPG.

Unfortunately the class C RV's have a tendency to scoop the air with the cabover.

I hope someone comes on here and gives us some good advice. I can't imagine "everyone" lying about the great MPG that this 22R gets.

 

could some of the problem be water in the holding tank or waste tank or add ons inside your camper. i get great mileage till i put stuff on the back of my 1 ton. also the manual tranny is better on gas if you can drive a stick.

 

This may be a long shot, but has the timing set ever been changed? If so, the cam alignment pin hole can be off by a very small amount, but the difference changes the cam timing enough to affect power and mileage.

With a 350 V8 in my Toyota 1-ton and 4-speed automatic, I get close to 20 mpg.

Good to know, thanks for the info.

The weight of the vehicle is certainly a factor, in my case tanks were dry nothing extra as far as cargo or passengers. In my opinion 15mpg on the freeway isn't too much to ask from automatic 22re even if it is a bit overloaded, especially since that is what is reported by other owners of identical vehicle. I would like to have a stick but I'd like to get this one getting better mpg before I sell it, as I will be honest with the mpg and don't want to scare away buyers...

Not to my knowledge, thanks for the tip it's something new I can try...

My understanding is that it is very close, if not already overloaded... remember why all those 5lug rear axles failed on units over 18 foot.

Have ya'll asked this over at toyotamotorhomes.com ?

 

The bad rear ends were the ones used on the pre-'85 truck, I believe. The '85+ used the same housing as the 4x4 and were built to handle the load. I need to swap in a Toyota full-floater in my my dually, as it has the original 2wd+doubled rims and doing 4-tire burnouts into Drive probably isn't too good for the diff.

 

Synthetic oil is always best, even with old units, Slick 50 oil w/ teflon has really helped with mileage of the many toys i have owned. Lets face it, the box is huge and like driving a wind dam down the road so that is why i bought the pop chinooks and an later model- 88' , that had lower profile box in front. Less space for my small family but better mileage. I always wanted to find someone who found a way to shapened /flatten the front of the overhead sleeper for better wind resistance. gt boise
