As you read this page, let’s imagine you and a group of the most highly trained, high- ly respected marine engineers in the world today are assembled under one roof. You have come together to pool your knowledge, your experience and your require- ments, and you are going to determine the specifications for the ideal Diesel Engine lu- bricant. Above all others, what requisite would you want? Undoubtedly, Minimum Carbon Residue, would you not? Alright, put that down. Next you would want Purity; and certain- ly you would want “‘Oiliness”’. You also want Body, Uniformity, Fluid- ity and Compression Seal. Now then, let’s check them over and see what we get:— Minimum Carbon Residue Purity “Oiliness”’ Body Uniformity Fluidity Compression Seal TEXACO URSA OIL For Diesel Engines has every one of these characteristics in a marked degree; and in one particular—its minimum carbon residue—it is absolutely supreme. And, the reason why TEXACO URSA OIL leaves no detrimental carbon residue is because it is non- blended, highly refined and because it is a distillate oil. Judged by these qualifications, wouldn’t your preference, the preference of the entire group, be unanimously in favor of TEXACO URSA Oil for Diesel Engine lubrication? We shall be only too glad to demonstrate the ex- ceptional lubricating ability of TEXACO URSA Oil to you, any time, any where. Such demonstration will prove to you why more and more marine engineers are using TEXACO URSA Oil for Diesel Engine lubrication—cleaner burning, surer bearing protection, easier starting, delivery of full power. Considering all these qualities the price is fair— and more than likely less than what you are paying now. ' THE TEXAS COMPANY TEMACO Texaco Petroleum Products iw Dept.
