I changed my oil last week with 4 quarts of Castro edge 5w-40 and half a quart of Lucas oil heavy duty oil stabilizer. wondering if I'm taking steps in the right direction to make my TDI last a long time? Is this oil safe for a 2002 TDI jetta? Is Lucas oil heavy duty stabilizer a good idea to add to my jetta? How long of intervals can I run with this particular setup? Any information would be helpful I would greatly appreciate it. I live in north Dakota summers 90-100° winters 0°- -30° it gets very cold here. Please tell me your educated thoughts.
