Re: [MBZ] Premium v. Regular was Re: Fuel prices
The Volvo geeks had a large data set, and decided premium bought about 10% MPG on the [279]40 series, which have the same deal as described. I don't know for sure that will be true with a Cadillac but it would seem reasonable. YMMV, and no I don't have a link. :( -TC -Original Message- From: Donald Snook dsn...@mtsqh.com Date: Tuesday, Dec 30, 2008 11:54 am Subject: [MBZ] Premium v.

Re: [MBZ] Premium v. Regular was Re: Fuel prices
I track my mileage on a PALM database. My HHR gets 10% going from 87
to 91 octane. Simple math even in my head when I fuel up, it hi-test
is less than 110% of regular, I use it.
YMMV

Re: [MBZ] Premium v. Regular
Here is all that I have to say on this subject... You drive a Mercedes-Benz. These cars are designed to run on gasoline that is much better than the goat's piss we can even get in the US. It costs what, $3-5 more per tank for premium? Much less expensive than the havoc the cheap fuel is placing on your injectors, ignition system, and even your rings at a minimum. The only MB I run on regular is the Unimog. It gets 12 mpg on a good day and has a 7.8:1 compression ratio. Your poor m103 with a 9 or 10 :1 CR, no wonder it is pinging! An no, there is not a knock sensor on that motor (at least the early ones). They will ping until they crack a ring and melt a piston. Look at the m100 (6.3) rebuild pictures on my website. That is what a lean mixture and advanced timing will do for you. Not much different than running crap fuel in a high compression motor. In the end one always pays... sooner (good fuel) or later ($$$ to your mechanic and parts dealer). If you can't afford to feed your MB good fuel, you should be driving a Toyota or Honda.

Mathieu www.oldworldauto.com Mathieu- My point to the original poster was that I didn't think the M103 had knock sensors so don't rely on a component that isn't there to save your bacon. My car did get 87, once. It was the only option at one point after hurricane this or that ~ 2 years ago. I know my motor started at ~ 9.2:1 and has probably had the head shaved so is a bit higher than that. That coupled with no knock sensor and a dislike for even 89 octane has taught me all I need to know. SHould take a look at your site but I've also seen pistons pockmarked from preignition- thankfully, not in my car. Tony Wirtel -- next part -- An HTML attachment was scrubbed...
