Geez, All I was asking was if anyone used lower octane and if they had a problem. I'll use super, I won't destroy the car.
My point was that I used 89 and 87 in both of my BMW's without a problem or apparent loss of power. I just wanted know if anyone had the same experience with a Benz.
I'll drink the Kool Aid now.
Hey, Michael. I realize you probably posted not even thinking it was that tough a question. But as I tried to point out -- not just for you, but for others as this has probably been discussed 100 times, compensatory mechanisms will prevent immediate damage, but you can't tell about the long haul, or even how long the haul will be.
But just because some people may have used lower octane and not noticed a problem doesn't mean one is not developing. Sort of like the difference between blunt-force trauma and Alzheimer's; just because there isn't evidence of the first doesn't mean the latter will is not still brewing underneath only to surface later.
Of course, one of the great things about owning a car is getting to decide how to maintain it. And if you aren't going to own it beyond 80,000 miles, then you can pretty much do what you want to it, odds are no serious damage will manifest in that amount of time. However, from an "abusing the car" standpoint, it does affect it, it's just that the subsequent owner(s) will be stuck with the bill. So I guess the end question is whether you're asking as an auto enthusiast that appreciates engineering and design, or just as a consumer.
Take care and enjoy the ride,
