How well does the VMM work in 4 days it has toled me my oil needs a changing it said it was good then went to soon and now it says now whats up with this i looked at the oil it fine any one others have this happen?
My VMM shows NOW after a very short time as well. My 89 SC was better about it but that was in 93. As time has passed, apparently the VMM just doesn't work properly. I clear mine about twice per oil change and I change mine about every 2500 miles. I wish I could tell you more about it. But it is very common for this to occur.
Most often it's not the VMM that doesn't work. Most likely the senders are faulty and that's causing the problem.... At least I had this same problem with my VMM.
