I am running the Rubicon at the end of September and am concerned about the amount of gas I will need. I have a CJ-7 with a stock LT1-350 out of a 97Firebird, Ford 9" axles with 4.56 gears, 38.5 Super Swampers and a 15 gallon fuel cell. I am thinking about taking two of these

to give me an additional 8 gallons of gas. I know that there are a lot of you that have run the Rubicon that would have a better idea of how much gas I may need. Do you think this will get me through? I appreciate any input that will be helpful.

First of all it depends on how many days you plan to spend on the trail. We've run the Con many times from Wentworth Springs up Cadillac then out to Lake Tahoe. Normally we take three days to do so. With TJ's we've never had a problem getting low on fuel. Our wheelers with CJ's normally put five gallons in their tanks at Rubicon Springs and make it out with no problem.

This is the best advise I have for you. :smokin:

when I went through.. 302/4.56's.. used up 10-12 gallons.. I think you should be fine..

I've run it a few times in my 73' Commando with a 401. 35's, 4.56 gears, and TBI.

I would fill up in Pollock Pines, drive to the trail, (through Loon) run it over 2 days, drive into Tahoe and fill up again. 17-18 gallons each time, and that 401 is a pig.

I was thinking it would be enough but I know we are planning on three days and I would hate to run out. Thanks you your input it helps put me at ease.

i usually fill up my 10-12 gallon gas tank at georgetown and have never had a problem running the whole trail in couple days. I dont bring gas cans. (georgetown to loon to rubicon springs-tahoe-highway 80) Usually have couple of gallons extra of gas by the time i hit the gas station near start on 80. Its a CJ-7- MPI 4.2 L 258 on 35's if that makes a difference, same ford 9 inch axle.

From loon to the springs and back on 39's with a 4.0ltr was exactly 10 gallons.

From Airport Flats through Wentworth to the Springs and back about 10-12 gallons.

350 , 5:38s, 35s

from georgetown to the end of the rubicon at tahoe in a 4.0 was under 10 gallons

from loon to top of caddy i use just over a quarter of a tank. TJ with a 4.0 5.13s and 35s

depends on how slow / fast you go and how high you rev your engine the whole way.

I filled up in placerville, drove the rig all the way there, did the trail came out on the other side and got fuel at a station some place. Cannot remember now. but I was running with probably less than 5 gallons left. My rig at the time had a 45 gallon tank.

bronco, carbed 400, manual, doubler, 5.13's and 39.5's when I did it.

Always take extra fuel with you. Even if you dont burn all the fuel in your tank, it is always a good idea to have fuel with you in case you need it because of an emergency, or someone else needs it.

Don't you mean WAS a pig.:flipoff2:

The 401 is still alive (in someone elses Jeep now) so it's still a pig. It's the rest of the Commando thats gone.

Are you running the Rubicon with us this year?

Not to hi-jack this thread, but yes.

My 383 is a pig also I have 2 20 gal cells I drive from tahoe to Ice house all the way through and back home on about 30 gal.

I just ran this past wkend from loon to buck continued down to the springs for the Marlin BBQ and wheeled back out at night camped back at buck and wheeled back to loon the next morning and just made it to the slabs and I burned 15 gals with a 304 V-8 and added 5 gals to get back to the spillway, but I did an extreme amount of idling, helping others......... Im thinkn of converting to propane

I think I will be shutting it off if I am not moving. I feel good about making it with the gas I am taking though.

Just got home from running the Rubicon today. 1st time with my new Jeepster. 350 chevy TBI, th-400, Dana 20 with 3.15, 4.56's and 35" tires.

Filled up in Fresh Pond, drove up to the trail - through Loon, drove to the springs and back (over 3 days), back down Ice House to Fresh Pond to fill up.
