Guest Juergen Posted June 14, 2010 Share Posted June 14, 2010 Hallo,I would be very pleased about some experiences about fuel consumption of a Master Six engine 1930 with 64 C Body.Is it ok, when it needs more than 20 liters for 100 Km, or do I have a bad adjustment of carb or something else (I drove 250 Km on german autobahn )Thank you for every answer and opinion.Regards from germanyJuergen Link to comment Share on other sites More sharing options...
jbbuick22 Posted June 14, 2010 Share Posted June 14, 2010 Juergen, 20ltr=5.2us gals, 100km = 62mls, Miles per gal = 12. Sounds about right for that car. JBBuick 22-6-55 Sport Touring Link to comment Share on other sites More sharing options...
John_Maine Posted June 14, 2010 Share Posted June 14, 2010 Just about what my '71 LeSabre gets. Not much progress in 41 years. Link to comment Share on other sites More sharing options...

tblack Posted June 15, 2010 Share Posted June 15, 2010 That sounds pretty good my 1916 D35 with all of 35 horse gets about the same. Link to comment Share on other sites More sharing options...
Guest 1937RHDNZ Posted June 16, 2010 Share Posted June 16, 2010 In imperial gallons thats close to 14mpg, my 37 buick, 248cubic inch, only gets about 12.5mpg. Mind you my 2010 Nissan Navara 4WD (Frontier) 4L, 244cu inch, V6 198kw or 261hp only gets 20L/100km around town, so I guess this is a common petrol consumption no matter what year the vehicle. I also believe that these older cars travel, on average, a lot faster than they were intended to, so that will push consumption up a lot as well.20L/100km for 1930 is pretty reasonable.

Guest Juergen Posted June 16, 2010 Share Posted June 16, 2010 Hallo,thanks for all the opinions. I feel better, when I know it is on average a normal consumption.In my car a carter BB-I carb is fitted instead of a marvel carb. Do you think it is a good solution or should I try to find an original one for normal driving ?Regards from germanyJuergen Link to comment Share on other sites More sharing options...
Mark Shaw Posted June 21, 2010 Share Posted June 21, 2010 Juergen, In my opinion, any updraft carb will not perform as well as a downdraft carb. The intake manifold is semmetrical so you can turn it up-side-down and install a downdraft carb to increase fuel mileage. Just don't change anything that cannot be put back to original....

Leif Holmberg Posted June 21, 2010 Share Posted June 21, 2010 On my Buick 1925 -25 I did as Mark is talking about,change from updraft to downdroft,but without any less fuel consumtions.2 liters for 10km is what my car want and exaktly the same with updraft as downdraft.

Guest Juergen Posted June 21, 2010 Share Posted June 21, 2010 Hallo,Mark, it´s a good idea to turn the intake manifold, when it is easy to do, I think it worth to try it. What kind of downdraft carb would you recommand to fit ? There are a lot of them on ebay.Thank you all for the replyJuergen Link to comment Share on other sites More sharing options...
