**PRO-SPEC^®** **Single-Viscosity Motor Oil**
SUPERIOR BASE STOCK ONE OIL FOR GAS & DIESEL INCREASED ANTI-WEAR EXCEEDS THE CHALLENGE HIGH TBN PROTECTION PLUS	PRO-SPEC® SINGLE-VISCOSITY MOTOR OILS are designed for heavy duty service in diesel and gasoline engines in both on-highway and off-road equipment.

PRO-SPEC^® SINGLE-VISCOSITY MOTOR OIL is designed to handle heavy duty equipment both on and off-road. It also handles the requirements of both gasoline and diesel equipment. This group of straight weight motor oils is the ultimate protection needed to extend equipment life, reduce down-time, and make the equipment more cost effective.

Superior Base Stock

These oils are made from low sulphur, sweet paraffin base crude oils. The solvent extracted neutrals used to manufacture these high quality motor oils go through several refining steps to make them suitable for this application. The solvent extracted neutrals are of a minimum 95 viscosity index (VI). The neutral oils go through a solvent extraction process that removes heavy undesirable substances that might lead to sludge, gum, or varnish under heated conditions. The solvent extracted oils then go through a hydro-treating process that improves the oil's oxidation resistance and their response to the high quality additives used by Texas Refinery Corp. One more step, called dewaxing, is used to improve the oil's cold temperature capabilities as well as improve their film strengths when temperatures get higher.

One Oil For Gas and Diesel

Quite often, with most commercial brands of lubricants, there is a need to stock two, three, four, or even five different types of oil. PRO-SPEC^® SINGLE-VISCOSITY MOTOR OIL helps reduce inventory needs.

Offers superior protection for gasoline and diesel equipment. This means one oil with reduction in inventory costs and needs. It also means that you minimize the possibility of putting the wrong product in a piece of equipment. This is all made possible due to the excellent base stock and the superior additive package found this line of oil.

Increased Anti-Wear

PRO-SPEC^® SINGLE-VISCOSITY MOTOR OIL meets the latest gasoline (SJ) specification as well as the latest diesel (CF) specification for single viscosity oils. This means one oil can be used in a mixed fleet to handle almost all types of engines. Texas Refinery Corp. accomplishes this feat by using two different types of high quality zinc anti-wear protection. One of the zinc compounds is activated by low temperatures for the gasoline engines. The other zinc compound is activated by higher temperatures for protection of the diesel engines. The finest of zinc additives are used for anti-wear protection. A large percentage of anti-wear additive is placed in the PRO-SPEC^® SINGLE-VISCOSITY MOTOR OILS. In fact, 0.12% zinc is the minimum requirement for this oil.

Exceeds The Challenge

Meets and/or exceeds the latest gasoline engine oil specification SJ, as well as the latest diesel engine specifications for single viscosity oils CF. This oil is a tremendous improvement over the previous specifications. For example, the Buick engine sequence III E test shows PRO-SPEC^® MOTOR OIL provides from two to eight times as much protection as many commercial engine oils against oil ring deposits. In addition, PRO-SPEC^® SINGLE-VISCOSITY MOTOR OIL doubles the valve train wear protection over many engine oils and also provides a 60% improvement in sludge control over many engine oils.

High TBN Oil

Has a high total base number of 15 Plus. This high TBN level indicates how well this oil fights acids and their corrosive effects. Many commercial lubricants on the market have a TBN level from only 6 to 10.

There are many different ways to boost the total base number of an oil. Texas Refinery Corp.'s PRO-SPEC^® MOTOR OILS received most of their alkalinity from the detergent value of the oil. Of course this is the most expensive way to go and it is certainly the most effective as well. High detergency TBN additives are more effective at controlling the overall effects of in creased soot loading of the oil. The high total base number end result is longer life and extended drain intervals.

Provides Protection Plus

Detroit Diesel has indicated they are against products with a high ash content, but they allow a lot of exceptions. The higher ash content of Texas Refinery Corp. PRO-SPEC^® MOTOR OILS does not cause a problem in Detroit Diesel engines. As a matter of fact, PRO-SPEC^® MOTOR OILS have proven to be beneficial. Those benefits are as follows: (1) Increased engine cleanliness, (2) Reduced engine wear, (3) A substantial reduction in piston and piston ring deposits, (4) A substantial reduction in piston ring breakage, (5) A more complete neutralization of the corrosive acids produced during the combustion process.

Just pick the proper viscosity as recommended by Detroit Diesel for the operating conditions and you will be pleasantly surprised by the excellent service given.
