i got some waste oil from a resturant..then filtered it straight away through a cotton t shirt folded over twice.. poured it straight in to the tank mixed at about 60wvo 40 derv with no other mods can i expect any problems the temp out side is 0 at night and 1 0r 2 degrees in the day

You can certainly expect problems. WVO needs to be filtered and de-watered before use. A t-shirt is not a filter, nor does it remove water. Blending must be done throughly before the fuel is introduced to the tank.

I strongly urge you to do a lot more reading and ask questions before you attempt the use of oil in your car again. Why did you decide to do this?

As 240 says you want to take a bit more care.

Your engine could be a good candidate for running oil. They come with Bosch (good 4 veg) or CAV (bad 4 veg) injection pumps

There are lots of people with the same engine doing similar at
