The fuel for internal combustion engines employing electrical fuel ignition and a carburetor and/or fuel injection, comprises a boiling fraction of 30.degree. C. to 200.degree. C., especially 30.degree. C. to 180.degree. C., containing hydrocarbons selected from the group consisting essentially of paraffinic, olefinic, naphthenic and aromatic hydrocarbons and mixtures thereof, and which is free of manganese, lead and iron. According to the invention, the fuel contains methyl formate in an amount in the range of 1.0 percent by volume to 50.0 percent by volume, if desired 1.0 percent by volume to 30.0 percent by volume, and preferably 3.5 percent by volume to 10.0 percent by volume of the fuel.

Fuel for internal combustion engines and use of methyl formate as fuel

Disclosed is a pointing compound for use in making repairs particularly to road surfaces. In accordance with the invention, the pointing compound comprises a mixture of mildly air blown bitumen, at least 25% by weight of polyolefin material selected from polyethylene, polypropylene and copolymers thereof and 10 to 40% by weight of a high boiling aromatic mineral oil. The amorphous polyolefin material preferably has a molecular weight ranging from 25,000 to 30,000 and a viscosity at 170.degree. C. of 2,000 to 5,000 cp.
