BMW not the originator of the dealer notification deal, I have been getting monthly emails from GM (On-Star) since at least 04 when I bought an Escalade. It gives u the % of oil life, tire press, abs, stabiltrac, airbag status etc. We also get a email from the dealer when the oil remaining % says to change. U get this info on even the cheapest Sonic now for free for 5 years, We use it on the oil, had a change last year last 9600 miles before reaching 5% as we were on the road constantly due to family deal out of state, but most come due around 5000 or so when we drive only locally. I do not change oil in my cars anymore, dealer will change, use Mobil 1 and rotate the tires for $60.00 and feed me a doughnut and couple cups of Kreuig Coffee.
I change bike engine @ 5K and use Mobil 1, Primary @ 5K using Redline Primary Fluid and trans @ 10K using Redline Trans. I still do the bike myself but I wouldn't if the dealer was not so messy. They did free change @ 1000 when I bought it and it came back with dripping oil from frame rails, bottom of bike. I exploded and wife said no more, you do it yourself. Dealer was probably glad after scene in service check-out area.
