Your saying the truck is reading along the same oil life left as the report is?
I was just looking to blindly change every 5k with Amsoil SS. But figured it might be premature. Unless I do the analysis, I rather err on the side of caution.
It seems that 1000 kms = 1% on the oil life gauge. TBN says I can go another 1000 kms to 11k kms.
I did the oil analysis just for proof and to make me feel better.
