My daughter's 2002 Chevy Blazer, 4.3 V6, uses a lot of oil. Doesn't smoke. Replaced PCV valve. It's a beater, so not looking to pour money into it. Going to switch to a thicker oil, 5W/40, to see if we can reduce consumption. 5W/40 blends are scarce and usually synthetic. I purchased Mobil1 for this go around.
What oil weights/ratios can I blend to come up with a roughly 5W/40 equivalent? Conventional oils are fine. Sump capacity with filter is 4.5 quarts.
