then how do you guys do it?

I blend mine one of two ways. First when going directly into my main tank I blend in my Centrifuge barrel. After cleaning the WVO I pour in my blend and let the pump circulate it for a while, I then pump it into the tank. I also have an auxiliary tank. In that tank I will simply do as you have asked, pump in WVO then go to the gas station and add some RUG or diesel. In this situation I am driving off of this tank and usually drive for a couple days before using that fuel, by that time I assume it is pretty mixed up. I have though blended as you mention in my main tank when the tank still has a good amount of fuel in it. I use a heated filter so I only do this when the engine is warm just in case it is too thick at first (I assume the heated filter will thin it)

My blend mixing and fueling station

i like rusty's plan about putting it right in the tank of a warm engine with the protection of a heated filter.. also because i know he's using a 6.2 and thats the engine i would be using as well

and sorry john i just thought i'd put that out there and anyone that read it and felt like contributing a quick answer could. in all fairness i've looked thru a lot of the pages on different forums too and i feel like i've done a good deal of looking on my own, didnt see the harm in asking i certainly wasnt expecting to be spoonfed and i apologize if it came off that way

It's good you've done the research and drawn your own conclusions.

If you have a heated system, and the engine temperature is up to where the entire system is hot, I don't see how there could be any problems with blending in the vehicle tank providing you drive around enough before shutting it off to make sure it gets mixed up really well. In fact before a trip a few weeks ago I had the engine warmed up really well, backed up to my filling station and pumped straight WVO into my main tank. I had a few gallons of blend in there so it was probably 95% WVO. I then drove about 150 miles to my destination. When I got there I topped off the tank with diesel and drove about 15 more minutes to my mothers house before I shut it down for the night. I put about 7 gallons in a 25 gallon tank so my blend after that was back to 60-70% wvo, about where I normally run it. The next morning it started up fine, it also drove fine with the 95% WVO, couldn't tell any difference. I think the answer for most is not to mix in the tank, but in certain circumstances it will work.

If the VO added to the tank is the same temperature as the fuel in the tank, then driving will probably mix them OK. If the VO added is colder than the fuel in the tank, then it will sink to the bottom and get sucked into the system. Some IPs will be very unhappy with a slug of cold thick VO.

Didn't think about the temperature of the fuels,good point.I think that just is another reason not to blend in the tank unless you have a heated system up to temperature.

i drive an 81 240 and it works just fine here in fl. i just put the kro or dino in first, my fatherinlaw does the same in his 83 benz

Older simpler fuel systems in hot climates are of course much more tolerant of tank mixing. Try that with a new truck in Minnesota in the winter and it could be a very expensive lesson.

I am in Texas so not too cold here either. I am switching to a Mercedes and am excited about the tolerance of those engines to wvo! I will probably still blend in my centrifuge tank before pumping into the car though but nice to know it can be done in the tank for trips.

It depends on the details of the "heated system" and the type of IP. In some cases it will work and in others it will damage the IP.

Generalizations about using VO will always be wrong in some cases and expensive damage will occur because someone did what they read was OK on some internet forum.
