Hi Guys

Hi Guys.

I started Hypermiling a few weeks ago with my 81 rabbit diesel 1.6 na and had some decent results.

416.6 miles used 7.4 gallons or 56 mpgs. these arent hyw miles but the back roads in east texas. Average Speed maybe 40 mpgs, never going over 50 and more often than not onder 40. I started doing engine off coasting this tank. the car has a 5 speed in it and i try to get in it as fast as i can on semi level ground or stay in 4th and just touch the gas peddle for the hilly areas.

I saw where Project Sipster got 84 mpgs with some areo mods and swapping the engine. Im wondering if i do the areo mods but no engine swap how high this thing might get. im no speed demon and am never in a hurry so hopefully someday we will see.

My first mod i think will be a full belly pan. i have an cow feeder on the property that has enough galvinized sheet metal on it to cover the belly. I think this will help a bunch since the back end of the rabbit undderbelly can catch a LOT of wind the way its designed.

Looking forward to reading more and learning more from the sight.

Thanks for reading, Don

Welcome.

The gains from mode will vary, but they do add up. Smooth wheels and grill blocks are two others you can pretty easily manage that will net you some decent gains. Also, don't forget inflating your tires to the max side wall or even over inflating if you feel comfortable.

Thanks Jsatter,

The Tires on the car are 155 80 r 13s pumped up to 60 psi. the max sidewall rateing is 44 : )

I will get to work on the grill block. though im not sure how long that would be usable here in East texas were probably a month or 2 from the 100+ temp days again.

Thanks, Don

Hi Jedi,

looks like we have a few east texas hypermilers on the sight. A lot to learn and have fun with.

Thanks Don

I managed to get a low '70's mpg once on a trip eastbound in western Kansas w an
'82 Quantum wagon w the same motor as yours.
I regularly got 52-57mpg on roads trips at 50-55 mph. I never got below 46mpg commuting
(admittingly 3/4ths freeway), and still go 32mpg. towing a 200# + bolt together trailer w
a small motorcycle, and bicycle strapped on for a camping trip in the mountains.

Keep up the good work. Is yours a 4 speed, or a 5?

Hi Larry,

the Rabbit is a 5spd in it.

A friend helped me mount a fuel cut off switch in it a couple of days ago as i was getting worried about burning up the glow plugs useing the key for off engine coasting. Im thinking this will ease my mind and ill do engine off coasting more now. You hitting the low 70s once gives me hope that i might can do the same.

My last tank was 56.2 mpgs with at the most 60 miles of freeway.

I am disabled and havent worked in a long time so most of my trips are within 10 to 20 miles of my house. Doctors, store for food and try to go to my friends once a week just to get out of the house LOL

Hopefully this spring i can get to work on some aero mods to help the rabbit cut through the wind a little better.

Thanks for reading, Don
