i thought as much about these products...either they didnt work at all or it would take more money for them to work because one would need to by in quantity which would surpass the money spend on the actual fuel....after reading an article on different acclaimed octane boost products, i'm convinced that it would be a waste of money to attemp to "upgrade" a lower octane fuel to the necessary level. $10-25 for a bottle that teats x gallon..maybe one will get two uses out of that..thats an addional $5 (minimum) per tank of fuel vs. an additional $3 per tank for the actual 93 octane fuel...

i've never heard pinging before...my fuel economy in the 190E is roughly 20mpg. I've still not gotten used to the fact that the tank is only 14.5 gallons. Seeing it sit near 1/2 tank and seeing near 125 miles since full got me worried. I'm so used to the w126's 23.3G tank.

Heres a question: on the fuel gauge there is markings for Full, 3/4, 1/2,1/4 and R...when the needle is on 3/4 does it mean there is 3.2 gallons or 3.6? Does the fuel gauge read the full 14.5G or does it read the 12.9 (everything but the reserve)?

gmercoleza,
how many years have you been going with that cycle..it gets pretty cold up here in the winter.

Ferdman,
the manual says a min. of 91 octane. Around here its 87,89,93. I havent seen any 91 in a long time and if I have its most likely going to be more expensive than the 93. I buy my fuel at a competitive truck stop area so fuel is always cheaper than the stations around town. when RUG was 2.85 at the corner station it was 2.65 at the truck stop.

lee polowczuk,
i thought about running a bottle of Techron through but was unsure if it would be worth it...I think its about $12/bottle for 20gallon and $9 for 12...

whats this BG44k do?

Thanks everyone,

Kris
