MARINE TWO-CYCLE ENGINE OIL

Texas Refinery Corp. incorporates modern ashless dispersants in their MARINE TWO CYCLE ENGINE OIL to virtually eliminate problems due to oil ash in these marine two cycle gasoline engines. Texas Refinery Corp.'s MARINE TWO CYCLE ENGINE OIL passes all TC-W3 requirements.

Texas Refinery Corp. has developed a formula with high levels of ashless dispersants thus allowing the use of lean fuel: oil ratios. Texas Refinery Corp.'s MARINE TWO CYCLE ENGINE OIL provides excellent lubrication and outstanding control of deposits and wear at all recommended fuel/oil ratios provided the oil is properly mixed with the gasoline.

MARINE TWO-CYCLE ENGINE OIL

Test #1 used a 70 horsepower outboard motor. After a two hour break-in period the engine was shut down for 60 minutes and the cylinder head torqued. Test conditions were alternated between power and idle phases for seven hours. The power phase lasted 55 minutes at 5,000 rpm. The idle phase was five minutes at 1,000 rpm. The fuel/oil ratio was 50:1. At the end of each seven hours the engine was again shut down for 60 minutes of rest. The test continued in identical seven hour intervals until 98 hours of running time were completed. Including the break-in running time the total test was 100 hours. The purpose of the test was to evaluate piston ring sticking, piston land and skirt varnish, combustion chamber deposits, ring cylinder and piston scuffing, exhaust port blockage and lubrication related damage. Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL passed all these areas with flying colors.

MARINE TWO-CYCLE ENGINE OIL

Test #2 used a 40 horsepower outboard motor. After a two hour break-in period (one at 3,000 rpm and one at 4,000 rpm) using a 50:1 fuel/oil ratio, the fuel/oil ratio was changed to 100:1. The test was then conducted for 98 hours on a 55 minute/4,500 rpm open throttle followed by five minutes idle time at 1,000 rpm. A one-hour rest period was given after each seven hours of running time. The purpose of this test was to evaluate the detergency and general performance of the oil. Piston varnish, ring sticking and general engine deposits were the primary evaluation areas. Here again, Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL passed all criteria in this severe test.

MARINE TWO-CYCLE ENGINE OIL

Test #3 used a 15 horsepower outboard motor. At first a break-in was run at 50:1 fuel/oil ratio under variable throttle conditions. Then the test was conducted for 100 hours at 100:1 fuel/oil ratio. During the test the engine was run at 5,500 rpm for 55 minutes and then five minutes at 1,000 rpm. After each 10 hours of running time a one hour rest period was given. At the end of each one hour rest period the engine cranking compression was checked. A 20 psig compression drop indicates ring sticking or scuffing. The purpose of this test was to determine the oil's ability to prevent ring sticking, piston skirt and ring face scuffing, non-uniform wrist pin discoloration and wrist pin needle bearing gum deposits. As with the other tests, Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL passed all evaluation areas with flying colors.

MARINE TWO-CYCLE ENGINE OIL

Two additional tests were run on Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL to determine the oil's lubricity and the incidence of deposit - induced engine malfunctions. Specific areas included pre-ignition, spark plug fouling, exhaust blockage and decrease in torque caused by high spark plug temperatures. Here again, Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL passed these tests. The lubricity test called for a fuel/oil ratio of 150:1 which is very little oil mixed with the fuel. The other test procedures ran at a fuel/oil ratio of 20:1 because this much oil makes many two-cycle oils fail the pre-ignition, spark plug fouling and exhaust blockage test. Texas Refinery Corp.'s MARINE TWO-CYCLE ENGINE OIL's excellent refining steps for the base oil plus use of superior additives means MARINE TWO-CYCLE ENGINE OIL passes all TC-W3 requirements.

Mixes Easily

The Texas Refinery Corp. product has additives blended in to help eliminate poor mixing of gasoline and oil. If thorough mixing is not achieved, stratification can occur and there will be too much oil at the bottom and not enough at higher levels. Burning the rich mixture at the bottom of the tank can cause plug fouling and smoke problems. Burning the lean mixture can result in scuffing or failure from lack of lubrication. The problem is most critical at lean fuel/oil ratios and is greatly aggravated by cold weather. In cooler weather, simply increase your mixing time to achieve a thorough mix. MARINE TWO-CYCLE ENGINE OIL can be used for inline or premix systems.
