My car is starting to use a little bit of oil between changes and my owner's manual says I can use either 0w20, 5w20 or 5w30 (in extreme situations). Well I decided I'd try to "thicken" the oil up a bit and mix the 0w20 with the 5w30 to see if it would reduce some consumption. Any problems with doing that? I figured it would just turn into a heavier 20 weight oil. Both are Mobil 1 synthetic...same bottle, etc...so I assume it's the same additive package.
The way my car uses oil is kind of strange; it starts out fine, no usage for the first 3,500 miles - after 3,500 I might add a half a quart till 4,500, but once it reaches 5,000 miles?? It drinks it to 7,500. I end up adding maybe a quart and a half/2 quarts between 5000-7500. My thoughts were that the lighter weight is shearing? And maybe going a little thicker will help. Like I said, the first 3,500 I won't lose a drop. And the car has no visible oil leaks. I suppose I could just cut the OCI's down to 5,000 miles, but with people going 10,000 miles and up, I figure 7,500 is pretty reasonable on a synthetic.
