    Abstract

    An engine lubricant comprising an oil and additives and method of making and using the same. The engine lubricant is based on process of sequentially combining a specific amount isopropyl alcohol, fuel stabilizer, corn oil and motor oil to produce a lubricant that prevents phase separation. The engine lubricant may be combined with gasoline to produce a two-cycle engine fuel. Alternatively, the engine lubricant may be used to lubricate 4-cycle engines. Prevention of phase separation in the engine lubricant provides longer engine life and reduced engine wear in both two-cycle and four-cycle engines.

    Claims

    1. A sequential process to prepare an additive consisting of the following steps of: in step 1, adding 60.39 to 66.75 vol. % isopropyl alcohol and 30.19 to 33.37 vol. % fuel stabilizer to a vessel; and in step 2, adding 4.42 to 4.88 vol. % corn oil to the vessel to form the additive.

    Description

    DETAILED DESCRIPTION

    (1) The invention will now be described with reference to the following examples:

    EXAMPLES

    (2) The base oil of the lubricant (Lubricant A) of the present disclosure used in the following examples includes:

    (3) TABLE-US-00001 TABLE 1 Preferred Base Oil Brand Availability 10w-30 Pennzoil 10W-30 Pennzoil Co. Motor Oil
    The additives for Formulation A used in the following examples include:

    (4) TABLE-US-00002 TABLE 2 Preferred Additive Brand Availability Isopropyl Alcohol Mac's NAPA 7100 Chemicals Thermo-Aid Fuel Stabilizer Lucas Lucas Oil Co. Flex Fuel Corn Oil 100% Mazola Co. Pure Mazola Corn Oil

    (5) The components of Lubricant A, in the preferred embodiment, are blended by a sequential adding process where, in the first step, the Mac's 7100 Thermo-Aid is added to the Lucas Flex Fuel. In the second step, the 100% pure Mazola Corn Oil is added to the combined Mac's 7100 Thermo-Aid and Lucas Flex Fuel. In the third step, the combined Mac's 7100 Thermo-Aid, Lucas Flex Fuel and 100% Mazola Corn Oil is added to the Pennzoil 10W-30 Motor Oil. After this sequential process of combining the components, the mixture was blended by gentle shaking. 15 seconds of shaking is generally sufficient to blend the components of the lubricant prior to adding the lubricant to gasoline.

    (6) It is important to combine the components of the formula in accordance with the sequential process described herein. When the components are combined in the disclosed sequential order, the components form a homogenous mixture. If the steps of the method of the present disclosure are not followed the components do not homogenize. Corn oil is surprisingly effective in generating the necessary homogenization of components when compared to other oils. The homogenization is an unexpected result and is critical for effectiveness of the present disclosure.

    (7) After combining Lubricant A with gasoline, the mixture is generally allowed to rest for at least one hour prior to use. When combining the lubricant with gasoline, no shaking is required for blending. Once combined, the lubricant and the present disclosure, the component amounts in vol. % for a preferred embodiment are disclosed in the table below.

    (8) Lubricant A (Brand Specific Optimal Mixture)

    (9) Add in sequential order:

    (10) TABLE-US-00003 1. Mac's 7100 Thermo-Aid 2.46 ml (2.079 vol %) 2. Lucas Flex Fuel 1.23 ml (1.040 vol %) 3. 100% Pure Mazola Corn Oil 0.18 ml (0.152 vol %) 4. Pennzoil 10W-30 Motor Oil 114.42 ml (96.729 vol %)

    (11) After approximately 15 seconds of gentle shaking, add the above combined mixture to 3785 mL (1 gallon) of gasoline.

    (12) The amounts of oil and additives are disclosed in generic terms below:

    (13) Lubricant A (Generic Specific Preferred Mixture)

    (14) Add in sequential order:

    (15) TABLE-US-00004 1. Isopropyl Alcohol 2.46 ml (2.079 vol %) 2. Fuel Stabilizer 1.23 ml (1.040 vol %) 3. Corn Oil 0.18 ml (0.152 vol %) 4. Motor Oil 114.42 ml (96.729 vol %)
    Add the above combined mixture to 3785 mL (1 gallon) of gasoline.

    (16) The vol. % of the components of Lubricant A listed above, may be optimally adjusted between approximately +5% and 5% of the first three components (isopropyl alcohol, fuel stabilizer and corn oil) and making up the difference with motor oil. In some embodiments, the isopropyl alcohol may vary between 2%-3.5%. The fuel stabilizer may vary between 0.75% and 1.75%. The corn oil may vary between 0.1% and 0.25%. Motor oil may be added to the first three components in approximately a 95-97 vol. % and may optimally vary depending on the ratio of gasoline to Lubricant A in the final fuel mixture. Optimally, the formulation comprises a sequential, stepwise process involving: 1. adding 1.975 to 2.183 vol. % isopropyl alcohol to a vessel; 2. adding 0.988 to 1.092 vol. % fuel stabilizer to the vessel; 3. adding 0.144 to 0.160 vol. % corn oil to the vessel; 4. adding 96.565 to 96.893 vol. % 10W-30 motor oil to the vessel to form the lubricant.

    (17) With regard to the fuel stabilizer component, a number of fuel stabilizers will achieve similar results. There are numerous commercially available formulations for gasoline stabilization that are commercially available and known to one of ordinary skill in the art and will work in accordance with the present disclosure. With regard to the corn oil component, 100% Mazola corn oil is preferably used, although other corn oils may also be effective. With regard to the base oil, 10W-30, 5W-30, 5W-20, OW-30, OW-20 and/or other comparable motor oils as would be known to one of ordinary skill in the art may be used in the present disclosure. The formulation is generally combined at approximately between a 32:1 ratio of gasoline to lubricant (Lubricant A) of the present disclosure to a 50:1 ratio of gasoline to lubricant (Lubricant A) to form a lubricating fuel mixture.

    (18) The list of components used in testing of the present disclosure is included below:

    (19) Lubricant A is Applicant's formulation in a preferred range approximate.

    (20) Lubricant B is Troybilt Remington MTD P/N 147543.

    (21) Lubricant C is ECHO Premium two-cycle engine oil with fuel stabilizer.

    (22) Lubricant D is Valvoline two-cycle Marine Oil TC-W3.

    (23) Lubricant E is Craftsman 50:1 Mix High Performance two-cycle Fuel.

    Example 1

    (24) Two identical blowers (Bolens BL125 two-cycle 25 cc) were tested to evaluate continual performance time. Lubricant A is applicant's formulation. Lubricant B is competing synthetic two-cycle oil.

    (25) TABLE-US-00005 TABLE 3 Run Time Lubricant (hrs.) A 16.0+ B 12.5

    (26) Results:

    (27) Lubricant A ran the blower for 16.0 hours prior to terminating testing, and an additional 22 hours without changing the fuel mixture after the testing phase was complete. Lubricant B caused the engine to fail at 12.5 hours. Therefore, Lubricant A significantly outperformed a comparable lubricant in the run time test on a blower.

    Example 2

    (28) Two identical Bolens BL 125 two-cycle Blower 25 CC 180 MPH Air Speed/400 CFM Air Volume were purchased new from a Lowes Home Improvement Store. Lubricant A, of the present disclosure, was used in one of the blowers, while Lubricant B (Troybilt Remington MTD P/N 147543 two-cycle Oil) was used in the other blower. Both units were filled with the appropriate gas/oil mix and started. Both units were run for various hours at least 1 hour per day. A log of hours run was kept. Table 4 shows the data from Example 2.

    (29) TABLE-US-00006 TABLE 4 Engine Engine Total Run Run Run Condition Reparability Lubricant Time Temperature Performance After Run After Run A 42.5 (engine Warm to touch Ran well Little wear and Would likely still running at tear; cleaner run if termination of and free or reassembled test). buildup on the sparkplug B 32.0 (engine Hot to touch Stalling at days Significant Could not be stalled and 6, 7 and 8; wear; scarring re-assembled could not be could not of the cylinder; due to wear restarted) restart on day 9 heavy carbon of the interior buildup on the operating spark plug parts

    (30) Results:

    (31) The blower using Lubricant A was still running after a 42.5 hour test period. The engine of the blower using Lubricant B failed after 8 days (32.0 hours total) of use. Lubricant A allowed the new blower to run through day 9 until it was subsequently turned off, at a lower temperature, with better performance and much less wear and tear on the engine than Lubricant B.

    Example 3

    (32) A 1990 Echo Series Blower Model # PB-210E was used for a period of 26 years at approximately 3 hours per week during the months of April through November, 2106. After this period, the blower was dismantled and the inner components and carburetor of the unit were photographed to document the condition of the engine. There was remarkable lack of wear and tear on the components, the carburetor was clean, and the motor was in excellent condition overall. Lubricant A is a preferred embodiment of the disclosure. The condition of the engine, in terms of wear and tear, was rated with 1 being a new machine and 10 being a worn out machine. Table 5 shows the data from Example 3.

    (33) TABLE-US-00007 TABLE 5 Engine Lubricant Condition A 2

    (34) Results:

    (35) The blower using Lubricant A left the machine in excellent condition even after a prolonged period of use where, according to a United States Environmental Protection Agency report, the median life for a commercial leaf blower is 2.3 years. (https://www3.epa.gov/otaq/models/nonrdmdl/p02014.pdf).

    Example 4

    (36) Lubricant A along with 3 leading brands of two-cycle engine oil lubricants (C-E) were mixed with gasoline and tested under extreme heat and cold conditions. Lubricant C is produced by a major manufacturer of law and garden equipment. Lubricant D is produced for use in outboard boat motors. Lubricant E is produced by a leading manufacturer of the new pre-mixed two-cycle engine oil and gasoline and is widely commercially available. For the heat test, the lubricants were heated from room temperature to 100 degrees Fahrenheit. For the cold test, the experiment was conducted over 7 days, where each test lubricant was cooled from room temperature to freezing temperatures (0 degrees Fahrenheit) then removed. The time for measurement of separation after extreme temperature exposure is between 30 secs and 1 minute. Results were measured on a scale of 1-10 where 1 prevented separation and 10 did not. Table 6 shows the data from Example 4.

    (37) TABLE-US-00008 TABLE 6 Heat Cold Lubricant Separation Separation A 1 1 C 6 8 D 6 8 E 6 8

    (38) Results:

    (39) Lubricant A prevented separation in both hot and cold conditions, whereas other comparable products did not.

    (40) JASO Tests

    (41) Two-cycle lubricants were prepared and their performance was tested. The performance of the lubricant was determined using the JASO standards currently used to test commercially available two-cycle lubricants. There are four levels of performance: JASO FA; FB; FC; and ISO EGD. JASO FA is the lowest standard and ISO EGD is the highest standard. The performance criteria that determine the quality of a two-cycle lubricant are set out in the JASO engine test sequences, details of which are available from the Japanese Automotive Standards Organization. A short summary on each test is given below. The tests determine the two-cycle lubricant's performance in comparison to a reference two-cycle lubricant of known quality, and they give the result as an index number.

    (42) For the purposes of the present disclosure, the parameters that are measured are the JASO Exhaust System Blocking Test (JASO M-343-92) and JASO Lubricity Test (JASO M-340-92).

    (43) The JASO Exhaust System Blocking Test (JASO M-343-92) determines the two-cycle lubricant's potential for the breakdown products on combustion to build up to such a degree that they affect engine performance, possibly causing failure, reducing top speed and increasing fuel consumption. This is referred to as the Blocking Index (BIX). The minimum index result for JASO FC standard is 90 and the minimum index result for JASO FB standard is 45.

    (44) The JASO Lubricity Test (JASO M-340-92) determines the load carrying capability of the two-cycle lubricant at elevated temperatures. The minimum index result for JASO FC standard is 95 and the minimum index result for JASO FB standard is 95.

    Example 5

    (45) JASO Exhaust System Blocking Test

    (46) The JASO Exhaust System Blocking Test (JASO M-343-92) test determines the two-cycle lubricant's potential for the breakdown products on combustion to build up to such a degree that they affect the engines performance, possibly causing failure, and more likely reducing top speed and increasing fuel consumption. This test results in a blocking index (BIX). The minimum index result for JASO FC standard is 90 and the minimum index result for JASO FB standard is 45.

    (47) For Lubricant A, of the present disclosure, the JASO exhaust block index=87. The result of the JASO Exhaust System Blocking Test for Formulation A demonstrates the ability of Formulation A to prevent phase separation and remain homogenous.

    Example 6

    (48) JASO Lubricity Test

    (49) The JASO Lubricity Test (JASO M-340-92) determines the load carrying capability of the two-cycle lubricant at elevated temperatures. The minimum lubricity index is 95 for all grades (FB, EGB, FC, EGC, FD, and EGD).

    (50) For the present disclosure the JASO lubricity index=98 and the JASO initial torque index=102. The result of the JASO Lubricity Test demonstrates that Formulation A ranks superior with respect to lubricity when compared to the benchmark oils.

    (51) This application discloses several numerical ranges.
