i have a chance to acquire stale rug from a small engine repair shop. how stale is too stale? the guy said some of the old gas is yellow or even green. i have been using kero and rug to blend with and this would reduce my costs. however, since i have had a problem with fuel pumps dying on me i am thinking of adding an in line vegetherm back near the tank in which case i probably shouldn't use any rug. so do i use more of the stale rug to thin more, or pass on the rug and use the vegetherm to improve flow?

thanks in advance

Are we talking about some kind of oil here, or a used toupee?

I've never seen green but have seen some stale rug that is fairly red, yellow should work great. I don't know what the problem might be other than possibly varnish, the older the gasoline is the more of the thinner volital chemicals will have evaporated away, these more volital chemicals are usually the ones used to up the octane rating, the less of these the better. I would think if the stale gas is thinner than veg it would be worth using but I can't say for sure. I would use it if I had it available but then I will pour about anything that is burnable into my blends.

I agree. Even with the new material, depending on the count versus the rating either before or after, it all depends on those variables.

By the way, what are we talking about?

WE are talking about using old stale, usually available free, Reguler Unleaded Gasoline (RUG) as a thinning agent in a straight veg fuel blend (not biodiesel), don't have a clue of what you are talking about.

billyjoe -- what is your vehicle and what pumps have died, some aftermarket electric pumps just are not up to handling thick fuel. Apparently the vegtherm works for straight veg just fine but can cause vapor lock if using RUG do to boiling the RUG out of the blend but this depends on many specific things in your specific setup. I blend up to 20% RUG ok but don't add any heat as of yet.

thanks for the info tim. i have a 2000 f-350, 4 wheel drive, 6 speed that i bought new. the original fuel pump went out a 68k and that was before i started blending. the second one went at 168k and that was just after i started blending and i am sure that was my learning curve. i started with dse's blend which is 85/10/5 wvo/kero/rug and i would run that without adding dino summer and winter. the next one went at 185k. the first 3 were ford factory pumps. i then went to carter pumps and they went at 201k and 209k. after the 3rd ford pump i started thinning my blend more but it hasn't seemed to help, even using 50 % blend and 50% dino. my blend now is 40 gallons wvo, 5 gallons kero, 5 gallons rug, 30 ounces of diesel kleen, 7 ounces of naptha. i also add 1 ounce of acetone to each 5 gallons of blend when i put it in the truck. and i run 50/50 blend/dino.
i did the hutch mod (changing the fuel pickup in the tank) which also added a large filter with a water drain between the tank and stock pump. i went back and read kugal's threads and bought the pump he uses but haven't put it on yet as i just changed out the other one. my next move was to put on the vegetherm as close to the tank as possible and then his pump between that and the new external filter and take off the stock pump.
the only other improvements are a super chip and a 4 inch turbo back exhaust which have been on since before 100k.
it gets driven every day for my landscape business and so there are 7 or 8 short hops in a day. once in a while it will go on a couple hundred mile trip.
i live in the sierra foothills in northern california. summers in the 90's, winters as low as teens and 20's, snow a couple of times a winter.
hope that wasn't too much info, but this pump problem has been a pain and i haven't been able to get any answers.
any help would be greatly appreciated.

thanks

i have a 2000 f-350 i bought new. original pump went at 68k before even using blend. put in another ford pump. it lasted until 163k which was a little bit after starting to blend with dse's formula. that one went at 186k, put in another ford pump. it went at 197k. did the hutch mod and put in new carter fuel pump. modified my blend to 40 gallons wvo, 5 gals kero, 5 gals. rug, 30 ounces diesel kleen, 7 ounces naptha and mixing blend with equal parts dino. that pump went out at 201k. new carter. next was at 209k.
i went back and read kugal's threads and bought the same type pump he has but haven't put it in yet as the carters are under warranty and so the last two haven't cost me anything except time to change out (which i am getting very good at). i am at a crossroads as to whether to get the free rug or just use kero and put the vegetherm on as close to the tank as possible.
i need to find someone who has done the hutch mod on a ford to discuss the clearance of the pickup in the tank. it is the only other place i can think of that might cause a restriction.

I've done the Hutch mod. Not sure what clearance you're talking about. I measured the distance to the bottom of the pick up on the stock configuration and then used the same measurement for the Hutch mod. I also upgraded the size of the fuel line from the tank to the fuel pump. I have a Dahl 100 filter pre-pump. At 145,000 miles I still have the original fuel pump, but I have a new one behind the seat for when it goes. I think it must be getting weak as my fuel pressure seldom reads above 50 PSI. It I stomp on the accelerator going up an incline the pressure will drop to the high 30s

I had 25L of stale 2 stroke which was a couple of years old. I just mixed it in with my biodiesel (about 10%) and I didnt notice a thing. I cant say what might happen with long term use, but i would have kept running it as long as I had it.
