  • Lube oil blend process and composition
    Patent number: 4213845
    Abstract: A lube oil blend process and composition are provided. In the process a raffinate lube oil stock having a superior sunlight stability is produced by contacting a gas oil with a suitable solvent under solvent-extracting conditions. The blend is produced by admixing raffinate and raw hydrocrackate lube oil stock. The blend contains, in parts by volume, for each 100 parts of the raffinate an amount of the hydrocrackate stock in the range from about 10 to 45 parts. The resulting blend exhibits a sunlight stability at least equivalent to that of the raffinate stock.
