A friend of mine has a new VW with the 2.8 V6 motor in it. It consumes about 1/2 quart per 1000 miles. His mechanic recommended that he use 10w-40 or 20w-50 to reduce the consumption. But, he also lives in a cold climate that gets down to about 10 degrees F. His delimma is this:
1. He wants to reduce consumption and is considering the heavy oil (10w-40 or 20w-50). But this oil may not flow well in the cold weather and cause some cold start wear.
2. He is concerned about cold starts and wants to go with a 5w-30 or 10w-30 but that means more consumption. He will just top off as needed.
What do the gurus advice he do? Option (1) or option (2)?
