THE ultimate in diesel engine protection. Amsoil Synthetic Diesel Oils' specially blended long-life formulation resists oxidation and thermal breakdown - retains viscosity and eliminates sludge and varnish formation. Outstanding lubricity provides unbeatable wear protection and maximum fuel efficiency. Twelve TBN formula fights corrosion. Contains special preformance additives for acid and soot control. Extended drain capability reduces downtime and motor oil expences. Designed to deliver 1,000,000 miles in over the road trucks befor engine overhaul. Exceeds stringent preformance specifications of all major American and European truck manufacturers. What Viscosity Should You Use? In most cases you can simply go with the manufacturers' recommended viscosity grade. However, there is an exception (isn't there always?). AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil has been designed specifically to be used for applications which require diesel oil specifications CG-4, CF-2 and CF.Its operating temperature range is quite broad, with a pour point of -60o F and a flash point of 489o F. In addition, the extremely high quality synthetic basestocks and long life additives which are used in our Series 3000 oils assure that they will maintain their high performance qualities over thousands of trouble-free miles. However, if you decide not to go with our Series 3000 oil, you can rest assured that you will still be pleased with the performance of our standard 15W-40 and other diesel motor oils. Learn the facts that the Truck manufacturers and the oil industry don't want you to know! The Truck manufacturers need to sell you vehicles, that's their business. Each Truck maker has product planned obsolescence built into their business plan. They won't tell you about or recommend AMSOIL synthetic oil because your Truck engine would last twice as long, that's not in their business interest! Also they make a tremendous profit on the 10 cent OEM oil that they sell (that's what it costs to manufacture). This OEM oil provides two functions, it keeps your Truck on their planned schedule for repairs and wearout and it adds a tremendously profitable add-on sale. So recommending AMSOIL synthetic oil that would make your Truck last longer and reduce their oil sales would be counter productive to their business plan.   INDEPENDENT LAB TESTS SHOW THAT AMSOIL'S SERIES 3000 5W-30 DIESEL OIL GIVES 82% BETTER ENGINE PROTECTION THAN OTHER COMPARABLE OILS! COMPARISON BETWEEN AMSOIL'S SERIES 3000 5W-30 DIESEL OIL AND OTHER OILS........ On road experience shows that conventional SAE XW-40 oils degrade within only 5,000 miles of operation! AMSOIL'S new Series 3000 5W-30 is designed for extended drain intervals and DO NOT lose viscosity like other oils. Series 3000 surpasses the API Energy Conserving Rating requirements and provides significant fuel savings, with significant oil savings in oil makeup for over-the -road service! Series 3000's extremely low volatility (7.8% Noack) demonstrates the oil's ability to withstand high temperature without losing viscosity. TRUCKERS WILL GET EXCITED ABOUT THIS OIL, IT'S 20 YEARS AHEAD OF OTHER OILS!!  Know the facts! AMSOIL will save you money. AMSOIL and a midwest fleet have been conducting a joint demonstration since Jan. 1996 comparing Series 3000 Synthetic 5w-30 Heavy Duty Diesel Oil to a popular 15W-40. Over the road testing is bearing out what we've known all along: Series 3000 is superior!! After a winter of record-breaking cold temps, a late spring and summer, the 1996 Kenworth trucks with Cummins N-14 engines participating in the AMSOIL Series 3000 fleet demonstration are approaching 80,000 miles or the one third mark in the 250,000 mile study and Series 3000 is looking good SERVICE LIFE AND PROTECTION. The five demo vehicles, which are running with Series 3000, a high quality after market full-flow oil filter and an AMSOIL By-Pass Filter, have received no oil or by-pass oil filter changes to date (9-96) Full-flow filters have been changed as necessary. Oil will be drained according to the findings of used oil analysis. All vehicles used in the demonstration kept the original manufacturer's oil until the first 20,000 mile oil change. At that time the AMSOIL Series 3000 was added. The five control vehicles, running with a top-quality national brand petroleum product and the same make high quality full-flow oil filter as that in the test vehicles, have received four installations of new oil and filters. Oil drain intervals are set at 20,000 miles. Oil analysis shows the Series 3000 in all test vehicles is fit for ongoing service, with a large safety margin between its performance after 80,000 miles and study contamination limits. In fact, at a drain interval now four times that of the control oil, Series 3000 shows superior overall performance. Even though AMSOIL Series 3000 has gone four times the mileage and oil analysis shows that there is less wear metals in the oil (after 80,000 miles), soot and solid accumulation per mile is lower, there is no viscosity breakdown in the Series 3000! Fleet personnel have noticed that oil consumption is lower in the Series 3000 vehicles.  AMSOIL SAVES MONEY! "AMSOIL gives our equipment the best protection from wear while allowing it to start easier,run cooler and get the best possible fuel efficiency. "D.D. Brownwood, Texas"     409,000 MILE OIL DRAIN INTERVAL / MACK TRUCK TEAR DOWN Fifth Wheel and Open Gear Compound AMSOIL Fifth Wheel and Open Gear Compound is based on proprietary technology that does not use asphaltic materials, residual compounded oils or diluent solvents as part of the lubricant formulation. It provides excellent adhesion to surfaces, resistance to water washout and protection against rust, corrosion, and wear. Virtually eliminates common deficiencies of residual oils and asphaltic compounds such as narrow operating temperature range, flaking, poor adhesion, water washout and environmental concerns. It is an aerosol spray product, making application quick, easy, neat and economical. Product Code: GFW Performance Features: Excellent resistance to water washout Environmentally preferable to solvent-containing formulations Protects ferrous surfaces from rust Excellent adhesion to metal surfaces Forms a tacky, tenacious film Heavy load-carrying and extreme-pressure performance Stays pliable at cold temperatures and does not flake off Series 2000 Synthetic Gear Lubes AMSOIL Series 2000 Synthetic Gear Lubes are race-proven extreme pressure lubricant engineered to meet the severe high-load and high-temperature demands of contemporary race and commercial vehicle differentials and gear-lube equipped transmissions. They provide the superior friction, heat and load control demanded by race drivers, the superior fuel economy required by commercial vehicle operators and the superior performance sought by all motorists. Friction Reduction and Fuel Economy AMSOIL Series 2000 Synthetic Gear Lubes offer exceptionally low coefficients of friction for superior power transfer, heat control and fuel economy. High Load and Extreme Pressure Performance AMSOIL Series 2000 Synthetic Gear Lubes promote long life for gears, including those subject to high loads and severe service. The superior film strength of their synthetic basestocks ensures protection from wear for gears operating with full-film lubrication. Top-quality extreme pressure agents ensure protection from wear for gears operating without full-film lubrication. High Temperature Performance AMSOIL Series 2000 Synthetic Gear Lubes offer the thermal stability and durability, oxidation resistance and shear stability required for optimal protection in the hot environments in which race and commercial vehicle gears operate. Thermal stability and oxidation resistance keep gears and seals clean by inhibiting the heat-induced formation of sludge and deposits. Thermal durability protects gears from physical damage by preventing heat-induced failure of anti-wear chemistry. Shear stability helps prevent metal-to-metal contact and wear in high-temperature operations. Low Temperature Protection AMSOIL Series 2000 Synthetic Gear Lubes are ideally suited for low temperature applications (see graph). Their low temperature fluidity ensures excellent low temperature performance, protection and fuel economy. Seal Compatibility and Rust and Foam Inhibition AMSOIL Series 2000 Synthetic Gear Lubes form a barrier on gear surfaces that seals out water to inhibit rust and corrosion. Foam inhibitors ensure protection in conditions that favor lubricant foaming and consequent metal-to-metal contact and wear. AMSOIL Series 2000 Synthetic Gear Lubes have been shown to help seals perform better and last longer.
