How far do you let your gas gage get before you start looking for fuel ? Also Octane

3/4 , 1/2 , 1/4

At 1/2 I start planning.

By 1/4 I'll be at a station.

I'll tell you guys about a great App that I love - iExit . Its available for iPhones, I'm not sure about the other phones. Give it a try.

Octane should be as per owner's manual no matter what you drive.

Depends on where I am at and where I am going. But 1/2 tank I start looking at 1/4 tank I better be filling up. On my motor home the generator won't pull fuel if I am below 1/4 tank. Run what passes for regular gas these days, 87 octane. If I can find ethanol free gas I will. If we are going to be staying somewhere for more than a couple of days I prefer to hit the campground with a full tank just to be prepared. I had power go out at a campground I was staying at due to storms, took about 36 hours to get it fixed. Several rigs had to leave and go get fuel because of their generators.

I run till 30 km till empty shows on my trip computer. I always know where fuel is and have a full tank going into desolate or rural areas.

We use Gas Buddy

We have an MBS 2400WS and I know I can safely go 250 miles on a tank of diesel fuel, so I start looking for fuel at around 175 miles if I am highway driving or 4 bars on the fuel gauge if I am doing a lot of rural driving (Sprinter fuel gauge has shows 10 bars when full).

When planning a trip (I use google maps) we drive a maximum of 6 hours daily which means one fuel stop somewhere in route. Seeing as we are pulling a trailer behind the motor home, I will figure out which town to stop in. I will then use the Gas Buddy app/website (set on Diesel fuel only) and will locate either a Speedway, Marathon, Mobil, or PB station. Once I get their address, I will then use google maps on "earth mode" so I can see the station layout to insure I can get in and out without any problems.

I won't drive out of my way to find the cheapest fuel but I may drive out of my way so I don't have to squeeze in and out of a station designed for autos only.

If I'm in a part of the country where cities may be 100 miles or more apart, I will fill up my tank at each city regardless of what the fuel gauge says. I figure it is better to be safe than sorry. Its another reason I carry a 5 gallon can of diesel fuel in the trailer when on extended trips.

I just started working on a 16 day 2600 mile trip for next April. I already have the main route picked out with stops at State Parks that have sites that will fit our rig. Next step will be Fuel stops along the way. Then some POI's. After that we play it by ear.


P.S. We do an extended trip in the spring before my golf league starts and in the fall after it ends. During the summer months we may do several weekenders but they are usually within 3 hours of home.

If I am on a familiar route with lots of options, I will bring it way down. This last trip, I was down to about 1/8, and contemplated bringing it one more service area on the NYS Thruway, as the next one had cheaper fuel, but it was cutting it too close. Unfamiliar routes that seem to lack options, I will be looking at around 3/8 of a tank.

MUCH Braver than me.

I have been to way to many pre-planned fueling stops where the only diesel pump is blocked by a gas vehicle whose owner is inside having dinner; the pumps are out of service; the station is under construction; there is a line of trucks 8 deep waiting their turn; the station in the iExit Book (or app) has a car sized rain cover; the campground is more that 1/2 tank away from the closest truck stop; I could go on ...

I Pre-plan stops at 3/8 tank (calculated - which works out as just under a 1/2 indicated) and carry two 5 gallon cans of diesel in the bed of the truck.

I find myself needing to use that fuel often enough during the camping season for one reason or another to rotate it regularly.

I have a 72 gallon tank. I have a three hour bladder.

Usually somewhere around 1/2. I don't like to run it below 1/2 because below that, I can't run the generator. (lowering the generator intake down to about 1/4 is on my ToDo list.)
