i know where an endless supply of free 15w-40 engine oil is. question is can i burn it for fuel? should i heat it up before it goes into the motor? start on diesel, run on oil? mix it 50/50 and go. forget it and just change oil really often?

 

Just change oil really often.

 

worth it to heat your shop with it.

 

i heat my shop with used motor oil. lol, got plenty of that on hand. cant get rid of it all winter

 

Yes you can use it as fuel. Start at a lower mix about 20% move up slow with each tank and see how much your truck likes. I was burning 80% with no problems on 6.4 2008. I also had to do the SCT DP delete so as not to clog it. Now when outside air temps. are getting colder I have to mix 50%. I have been doing it for 20K miles.
Now as for lubercation add 2 stoke oil. I use 2 cups for 10gal and acidtone to help with the burn.

 

how much acitone per 10 gal? and if you get too much does it become a problem with cold temps. it never gets below freezing here so im probly okay

 

how much acitone per 10 gal? and if you get too much does it become a problem with cold temps. it never gets below freezing here so im probly okay and would there be any difference between using new motor oil and used motor oil. because i can get all the fresh motor oil i want.

 

It has beed said that 1 to 3 OZ for 10 gals is good but no more. If you put too much in your tank than your MPG will start to fall off. Also I forgot to say that filtering is important, I filter to 5 microns and you can get new oil that will help going though the filter faster. I mix mine up in a 30 gal drum than add the diesel, 2 stroke oil and acidtone. From there it gets pump to the truck.
