Does anyone know the worst Cadillac on gas? How about the biggest Cadillac engines? Heaviest Caddy? My 79 Sedan Deville is killing mr right now with gas...
Stay out of Calif! Gas is $2.69, $2.79, $2.89 for reg 87 oct, mid 89 oct, & prem 91 oct. this AM and going up about 20¢ a day!! ... Re: [Vintage_Cadillac]...
The largest engines were the 70-76 500 cid. I think '73s across the board were the worst. Heaviest were the '75-76s. Dude, you're driving a Cadillac, not a...
Well, Cadillacs are definitely built for comfort and looks and not for economy. My daily driver is a '56 Eldorado w/2-4 barrels. I live in San Jose, CA....
I have a 74' Coupe, 1990 Lincoln Town Car, & 1993 Ford E-150 Cargo van and they all get about the same mpg. It's killing me, but not bad enough to want a...
Over here in teh United Kingdom it's the equivalent of about $9 an imperial gallon, a little larger than an American gall, but not that much....so running any...
I feel everyone's pain. I can't stand small cars, I feel like I am riding in a go-cart. Gas is high, but if you take into account inflation we are actually...
My 61 Fleetwood gets just about the same mileage -- 10 mpg at the best. Right now it's sitting in the shop getting the transmission worked on, so I'm driving...
Stuart, We just hired a guy from Canada, and they're paying $1.00 per liter, roughly $4.00 per gallon. He's happy to be paying only $2.50. Hawaii is also...
This octane comment got me wondering about my 1974 Coupe DeVille. It will sometimes stall when I give it gas after a stop and the engine "stutters" under more...
I don't want to start a political argument, but whatever the current price of gas is, one can't help feel like we're getting ripped off. Every corporation and...
I don't think leaded or unleaded is the issue. I have some early 1970s Camaro GM brochures and they mention that the engines are now being designed to run on...
*www.500cid.com MTS's #3 cam is an economy cam which supposedly will give you over 20 mpg. They claim the record is a 1976 Sedan DeVille with a 500 that gets ...
My 1975 Caddy Coupe de Ville gets 8 in the city, 11 on the highway...where I am stuck living in Salinas, CA of the USA, gas for just plain regular runs $2.80...
Jeremy, Back in the day of leaded gasoline.... I'm sure the Cadillacs all used premium gasoline (octane around 93) with lead. Lead doesn't affect octane, but...
Pete, Just my 2 cents here. All the Indy cars ran this year on 50% ethanol, and next year (or maybe it's the year after) they will all run on 100% ethanol....
Hi Joe, Interesting information--thanks for the report. I wonder how much more expensive the indy gas is compared to the stuff we're using now? Pete ... From:...
Actually Indy gas, while it is 10% ethanol, is 90% METHANOL (wood alcohol). My problem with the use of ethanol is that fossil fuels have to be burned to...
unfortunately the choice of adding or not adding alcohol/ethanol does not necessarily rest with the oil companies but a regulatory requirement for oxygenates...
Both tetraethyl lead and Ethanol have been used as oxygenates--to increase the octane--of gasoline. the choice to use lead back in the 1920's seems to have...
I agree with you that getting us off imported oil ASAP is a wonderful thing. Shale conversion is now economically feasible. ANWR needs to be drilled. And...
