What engine oil do you use in your gas E70?

[Entropy]

First off, oil threads, for some reason, can go sour quickly... so let's try to keep this one positive. Remember to keep in mind that (most) of us are not petroleum/chemical engineers and there is a lot we don't know.

Things to include in your post:

1. Which engine do you have and mileage
2. Typical climate your E70 operates in (temperatures, etc.)
3. Oil brand and specific type (a link to the oil webpage or PDF technical data sheet would be great as well)
4. Oil filter brand
5. Typical oil change interval
6. List any additives used
7. And a brief note about why you chose said oil/filter/additive would be great

Remember, this is for gas engines only. For you diesel folks, feel free to copy this post and create a diesel specific thread.

I think this thread could be a great reference thread for those who would like to start performing there own oil changes.
