I know, 10 year old thread.
Putting this Kreen stuff made by in my modified BMW e30 325i. Kreen is a thin green-colored solvent that smells good. I've used Kano's Kroil for years and don't have any strong feelings about it.
Anyway, I was noticing a quart of oil use every couple of tank fill-ups in the BMW. But mainly want to thin my thicker summer oil for this unusually cold winter we're having. I put a pint in the tank, a pint in the oil. It's my relatively cheap but fun (very fun) daily driver. If it helps, I'll try in in my Carrera. All my vehicles suffer from repeated short trips.
