This is just me: But I do not need a computer generated indicator to say: Change yer Oil. I just need to know miles, time, the most type of driving I have done, and pull out the ole dip stick and look, smell and feel, but that be old way GM checking, LOL...
DA BOIRD
ADDED: I also understand there R PPL who do not either care, know how to, or even take the time to check etc and need dat ole: Ding Ding: Change yer Oil reminder...
Changing the fluids: Like the Most Important thing U can do on yer ride religiously plus filters and run good gas/diesel.
